ABSTRACT: A new alloy ("Amg6T") of good weldability and a compar-
atively high strength, containing 6.5% magnesium, upto
0.7% manganese and up to 0.3% titanium, was recently de-
veloped. Fist tests to weld this alloy over a layer of
"MATI-l" and "MATI-5" fluxes (composition given in table
1), carried out with the participation of Yu. S. Dolgov,
Senior Teacher and A.G. Makhortova, Assistant, Engineer,
revealed abundant gas liberation caused by magnesium eva-
poration. fielding "Allg6V-alloy :)lates of ( - 9 mm thick-
nesa of a MATI-10 flux layer gives weld joints of a strength
similar to that of the base metal. As magnesium losses re-
duce ths strength of the sesm metal, measures must be taken
to increase magnesium content in the seam metal. In welding

TITLE- A Method of Determining Hydrogen Content in Seam Metal and the
Equipment Used
PERIODICAL: Svarocnnoye proizvodstvo, 1960, No. 10, PP. 13-16
TEXT: At the department "Technology of the Welding Practice" of KATI a
method was developed an an equipment devised for determining the hydrogen
content in Al welds. Two 7 mm thick pure aluminum plates with an initial H
content of 0.08 cm3/100 g, were welded on a copper backing in argon atmosphere
with consumable electrodes of 1.3 = diameter and 0.62 o;3/100 H content,
Specimens were turned from the central portion of the weld joint and stored in
tetrachloride carbon. The determination of H was made by the method of vacuum
extraction on an installation developed with the assistance of A. P. Gudchenko,
using a palladium capillary instead of an oxidizer. The method is based or, the
heating of the specimen to a temperature at which a sufficiently effective H
liberation takes place. Heating is performed in a vacuum and the amount of gas
liberated is determined from changes :in the pressure at a given volume of the

system. The installation (Fig. 1, 2) includes both an extracting and analyzing
system. The extracting system consists of a preheating furnace with a quartz
tube, a charge device, diffusion pumps and mercury seals. The analyzlrg sy~teln
includes a compression manometer for the measurement of the gas pressure, A
gas-collecting balloon and a palladium capillary placed in a heater, Evazua-13-n
is performed by a forevacuum oil pump and two mercury vapor diffusion Pumps.
The installation ensures high hermeticity and accuracy of measurement of the
changes in the volume. The total H content In the metal is found by sunning up
the hydrogen in the pores and in the solution. The H content In the solution is
determined by vacuum extraction; H in the pores is found by the weight method.
Special experiments were made to set up optimum eSnditions of H analysis a* an
initial H content in the ingot as hIgh as 0.69 cm /100 g, which are; prelimirar-)r
evacuation time; 2.5 hours; time of extraction from the specimen: I hour,
time of H diffusion through the capillary: 10 min. The method and eWuipmen-.
may be used to determine hydrogen In the seam when welding various metalls, to
study kinetics of H and metal interaction during welding process; to determine
the effect of H on the proper-ties of the seam metal and to reveal varlous da-fe2ts
arising in the weld joints. There are 4 tables, 7 figures, and 2 Soviet refer-_nreE.

higher hydrogen concentration in the metal itz content in the solution remains
practically constant attaining 1.5 - 1.7 cm31100 g. All the hydrogen above this
limit is separated out in the form of pores. The authors based their concepts on
the assumption that the liquid metal suffers an I-atm pressure from the surround-
ing atmosphere. This is applicable for pure aluminum. When welding aluminum
alloys, a portion of the liquid enclosed between the crystals, which were already
formed, is not subjected to external pressure. In this case bubble formation can
be expected at an internal pressure below I atm, and, consequently, at a lower
hydrogen concentration in the pool. The possibility Is investigated of eliminat-
ing hydrogen bubbles floating up in the pool. It can be assumed that degassing-
of the metal as a result of the floating up of bubbles is only possible at a
hydrogen concentration in the pool exceeding 0.69 em3/100 g. The conclusion is
drawn that the elimination of bubbles depends on the initial hydrogen concentraticn
in the pool. Under conditions of metal cooling, as in welding, the elimination of
bubbles from the pool is only possible when welding gasified metal and Is hardly
.probable in the case of a metal with a relatively low content of dissolved hydro-
gen. To check these conclusions the authors determined the hydrogen content of
beads welded on aluminum plates with a different hydrogen content, using 1.3 mm

TITLE: Nucleation and development of pores in welding AMr6 (Amg6) alloy
PrRIODICAL: 5varochnoye proizvodstvo, no. 12, 1962, 1 - 5
TEXT: Information is given on results of Investigating pore formation in
welding beads onto AMg6 alloy plates with a wire of the same material and of
pure aluminum. It was found that pores are formed in welding the A1Mg6 alloy, as
a result of a developed interaction between the liquid metal and the moisture,
contained in the particles of the oxide film; these particles are present in
the welding pool when the base and filler metal have melted. At a greater thick-
ness of the oxide film, the effect of moisture may be inhibited until completed
crystaliization stages. Then, besides pores of regular shape, which have par-
tially floated up to the surface, cavities of irregular, branched shape are
formed as a result of displacement of eutectic by liberated hydrogen. ailging
of the metal In weld adjacent zones and the appearance of cracks in the joints,

which have been previously produced by multi-pass welding, are connected with
diffusioii of hydrogen dissolved into microcavities and with the Increasing pres-
sure inside same. The basic measure to prevent pore formation in welding the
AMg6 alloy is a reduction of the oxide film thickness on the surface of the wire
and the parts to be welded. For Vils purpose It is recommended to conduct the
welding process with a wire, plated with pure aluminum or having a polished sur-
facq. There are 8 figures and 3 tables.

1ABSTRACT: The unsatisfactory weldability of SAP-parts noted in
fusion welding is caused chiefly by the p'ressnce of oxidelfilms en-
veloping each metal particle. The weldability can be greatly im-
:proved by vacuum annealing of SAP billets at 650--i-680C prior to
rolling. Weldable SAP sheets are obtained in this way. Thar have
higher ductility and almost the same tensile and yield strength as
those of conventionally processed SAP sheets, Weldable SAP sheets

ABSTRACT: Strain hardening of the alloy AL9 (6-8% Si and O,C-..O,'+%
Mg) during heat treatment Is due to the chemJ--al
compound M92Si. At 5950C tt.9 soLubility of th.? Mg-~'Sl
compound is 1.85% wh.1-1st at 200C Jts solubility in the
aluminium solution is practically nil, Cast AL9 alloy
components are usually quenched from 5350C in water, and
artificially aged at 1700C for 5 hours. In order tc
establish the possibility of reducing the heating time
during ageing, special Investigations were carziel cute
Specimens were rut from components of AL9 alloy materi-I
cast into the ground. The specimens were quenched f-rom
5350C in water at 60-800C. The ageing temperatures were
175, 185, 200 and 2150C and the ageing durat ons were 30:
609 90, 12-0 and 180 m1n respectively. The obtained

mechanical characteristics as a function of tLe agelng
time and ageing temperature (Fig 1 shows the dependence
of the mechanical properties on the ageing temperature
and ageing duration). Analysis of the experimental data
revealed that ageing at 2000C for 120 min y1elds the best
mechanical properties. Dilatometric investigations of
the alloy were effected by means of a differential
dilatometer. The comparison standard was made of
annealed, commercially pare aluminium. The results of
the dilatometric tests on specimens heated to 170, 180
and 190 OC during the Isothermal ageing (Fig 2) indicate
that with increasing temperature the speed of internal
transformations increases sharply. The dilation graph
obtained during heating to 2200C with subsequent
isothermal holding at that temperature indicates that
important Internal changes take place 1n the alloy during
the first hour. It was established that ageing at
temperatures above 2200C Is Inadmissible since it does
not permit obtaining the necessary strength, Corrosion
Card 2/3 tests of the alloy carried out in a 3% solution of NaCl
for a period of 53 hours have shown that specimens which

batches of components made of the alloy AL9, after ageing
at 1900C for 1.20 min revealed that the entire batch of
2000 components was satisfactory from the point of view o1
hardness. A reduction of the ageing time from 300 to
120 min will result in a considerable increase in

ABSTRACT: The task of determining the density of electron states in the
case of an emission spectrum consists in the solution of an
integral equation. The existing methods developed by
Vaynshteyn, van Cittert, and others are very faulty. Here a new
method, which is free from these faults, is described. The curve
diagram is decomposed into a number of horizontal rectangles,
and each rectangle is a difference of two steps of which one
has a ledge on the right and the other on the left branch of the
curve. The method offers the advantage that no computation is
necessar-j for the determination of the step parameters as is the
case with other methods. The disadvantages of this method are:

It is limited by the case of the distortion of dispersion,
and, with an increase of the ratio between the extension and
the half-width of the line to be corrected, the accuracy of the
method decreases. There are I table, 5 illustrations, and
6 references, 4 of which are Slavic.

TEXT: The adjustment of the new spectrometer is comparatively slm~.Ie Una
takes only a few hours. The crystals can be taken out of the ap:Daratus
without disturbing the adjustment. The distance betTeen the rotatinE axes of
the crystals is 100 mm. The focus of the X-ray tube is 300 mm dista4t from
the rotating axis of the first cryst~_l. The distance of the rotating axis CC
the second crystal from the window of the Geiger counter is 100 am. The
second crystal can be rotated by :t 1.50 from the middle position reading
accuracy 0.010). The spectrometer is not adjusted by means of the crystals
but by glass plates. After adjustment, the crystals are inserted to deter-
mine the CuKo( 1 - line and the angle between crystal surface and lattice
planes. Eight horizontal plates were built into the collimator to reduce

the vertical scattering of the beam to a minimum and yet to obtain hi--n
radiation intensities. A beryllium plate inserted between tfte coll1mator
and the first crystal is to eliminate the focus drift and the effect of
feeding-voltage fluctuations. It was difficult to choose the suitable
crystals since extreme optical uniformity is required, and the angle between
crystal surface and lattice planes shall be as small as possible . TtS
maximum was 105". Plates parallel to (10fO-) and (11fO) were cut from
various quartz crystals and investigated after etching. The -)urity of t~,e
two crystals is determined by the width of the reflection curves. The
quality of the plates is estimated from the shadows produced by deviations
of the refractive indices. A final examination carried out by -.Cans of a
polarization system indicates optical inequality of the elates by
spots. There are 6 figures and 6 referencest 1 Soviet and 5 non-Soviet.

ABSTRACT: The W doublets of the elements of atomic number from 24 (Cr) through 30
(Zn) were recorded with the high resolution two-crystal spectrometer of the Rostov
State University. The instrument and the experimental procedure are discussed else-
where (M.A.Blokhin. A.B.Gillvarg, loYa.Kikiforov, V.P.Sachenko, Izv.AN SSSR,Ser.fire
26,397,1962). The resolving power was approximately 38 000, the dispersion was 0.01
X per second of arc, and the angle could be measured to �0.5". The Cr and. Ki spec-
tra were obtained with Cu anodes on which Cr or Ki had been electroplated. The oth-
er spectra were obtained with Cu anodes into which powders of the corresponding me-
tals had been pressed. The double reflection curves with parallel crystals were
quite narrow (0.15 to 0.21 eV). The widths of the =1 lines were corrected for In-

strumental broadening by simply subtracting the width of the corresponding parallel
crystal double reflection curve. One spectrum (Cu) was corrected by a more rigorous
method (V.P.Sachenko and I.Ya.Nikiforov,Optika I spektro.13,447,1962) with practical-
ly identical results; the corrections are therefore believed to be adequate. Of the
published measurements of the =1 widths of the iron group metals. the present mea-
surements, those of G.Brogren (Arkiv.fyz.23,219,1963), and those of A.Meisel and W.
Nefedow (Z.phys.Chem.(DDR),219,397,1962) were obtained under the r-st advantageous
conditions with regard to instrumental broadening. Although there is considerable
agreement among the three groups of data, there is also some disagreement among the&
The =1 asymmetry indices were calculated, and they are compared with data of other
workers and with the magnetic moments. Although the correlation between 101 asymme-
try and magnetic moment is strong, it is not perfect. Notable deviants are Cr and
Cu, both of which are much too asymmetric for their small (or vanishing) magnetic
moments. The copper spectrum was corrected for the width of the K level, an4 It is
concluded from the shape of the corrected curve that the asymmetry of the CU spec-

X-ray structure analysis
ABSTRACT: The 105 bands of Fe, Ki and Cu, and the 101 lines of Fe and Cu were re-'
corded with the two-crystal spectrometer (resolution 38 000) of Rostov State Univer-
sity (N.A.Blokhin, A,;B.Gillvarg, I.Ya.Nikiforov and V.P.Sachenko,Izv.AN SSSR,Ser.
:fiz.26,397,1962). Quartz crystals cut parallel to the (1120) planes were employed.i
The Fe and Cu spectra were obtained with anodes of the respective metals. The Nt
spectrum was obtained with a Cu anode on which UL had been electroplated. The x-ray
tube was operated at 35 W and 20 m4. An accuracy of 2% is claimed for the ordinates
of the published spectral intensity curves. The shapos of the Cu and Fe 101 lines

were recorded because of their technical importance for precision x-ray structure
analysis. They are presented graphically but are not discussed. It is not possible
to obtain reliable widths Of the K35 bands without correcting for the width of the
K level and removing the to"' satellite. This analysis was not performed. The widtbo
at half maximum increased with increasing atomic number, corresponding to the in-
creasing density of free electrons between the Is and 3p shells. the principal
peak of the Cu band was found to be double. The two peaks are ascribed to the 105
and 102 lines, although the assignment is regarded as arbitrary because of the
strong hybridization of the conduction band. The Cu 10111 satellite was clearly re-
solved into two satellites, which are designated by 10 off and to 1 1;. Weak structure
(2
was found on the long wavelength side of the Ni and Fe bands. This could be due
to a long wavelength satellite, or to zonal structure of the electron states in the
lattice. The fe 105 peak was broad and nearly flat. Previous calculations of the
Fe 10s band shape (I.Ya.Kikiforov,and M.A.Blokbin, Izv.AN SSSR,Ser.fiz.27,314.1963)
are compared with the present measurements, and considerably better agreement is
found than was previously obtained with the measurements of J.A.Bearden and C.H.
Shaw (Phys.aov.48,18,1936). The calculations do not reproduce the structure on the
long wavelength side. The paper cloaca with a short essay on the role of x-ray
spectroscopy in the development of solid state physics. Although it is not possible

to obtain electron densities by simply dividing x-ray band intensities by transitiM
probabilities as envioaged 30 years ago by H.Jones, N.F.Uott and H.W.B.Skinner (F4y&
Rev.45,379,1934). one can nevertheless employ different approximate m3thods for
dealing with the many body problem to calculate x-ray band shapes, and by comparing
the calculated shapes with experimental data one can select the most promising
mathematical methods for further development in connection with solids of particu-
lar types. Orig.art.has: 3 formulam and 3 figures.

ABSTRACT: In continuation of previous theoretical and experimental inveStigAtiong
of transition metals of the palladium group (I.G.Shveytser, V.P.Sachenko and I.Ya.
Kikiforov, Izv.AN SSSR,Ser.fiz.27,319,1963) the 1432 emission and LI11 absorption
spectra of Me and Kb are compared, and their differences are interpreted in terms
of the energy level distributions in the metals as calculated in the orthogonal
plane wave approximation. The Me spectra and energy level distribution are taken
from the earlier paper. The Nb emission spectrum was taken from work of M.I.Korsun-
.sk:Ly and Ya.Ye.Gankin (Izv.AN SSSR,Ser.tiz.25,1028,1961) and the Nb L111 absorption
ippectrum was wasured for the occasion. The spectra of the two netals are rather

ACCESSION XRt AP4038764
aimilar, but the following differences are noted: the 1432 emission band of Mo is
both wider and more symmotric than that of Nb, and the first LIXI absorption line
of Kb is wider than that of No and its maximum is located farther fron the absorp-
tion edge. Since no self-consistent wave functions are available for Nb, and since
orthogonalized $later functions proved to be insufficiently accurate, the atomic
parameters of Xb required for the orthogonal plans wave calculation, namely the
Fourier components of the atomic potential, the orthogonality coefficients, and the
energy eigenvalues, were obtained by extrapolation from those of Mo. The extrapola-
tion of the energy eigenvalues was performed with the aid of Moseley's law, that of
the orthogonality coefficients by means of Hartres's scale transformation of the
wave functions, and the Fourier components of the potential were extrapolated by
first calculating their dependence on the atomic number with the Fermi-Thomas model.
Thirteen orthogonal plane wave functions were employed in the calculation of the
energy levels; the method of calculation is described in more detail in the earlier
paper. Considerable differences were found between the level distributions In go
and Nb. In particular, the maximum density of d levels occurs near or below the Fer-
mi surface in Mo and considerably above it in Kb. The LI11 spectra of the two metals
are discussed in some detail in relation to the level distributions, and all %!~_A
differences noted above are successfully Interpreted - in one case (the width of the

tions of the energy structure of a solid can sometimes make it possible to inter-
pret x-ray spectra senIquantitatively. Orig.art.has: 3 formulas and 3 figures.
