Leningrad Kirov Works
PERIODICAL: Znergomashinostroyeniye, 196o, No-7, PP-31-34
TEXT: Steam turbine blades manufactured in the Leningrad
Kirov
Works are grouped into three classes according to difficulty
of
manufacture. The first group includes those easiest to make;
they are those of constant section and are usually
cold-rolled.
The second class includes wholly or partially milled blades,
with thickened-root and constant blad1e profile in the
working
section. The manufacture of these blades calls for a great
deal of machining and special fixtures, cutters and gauges.
The third group, the most difficult to manufacture, includes
fu.Ily-machined blades with complicated roots, such as
skew-milled:
and screw blades, whose profiles vary over the working
length.
Manufacture of these blades requires a great deal of
machining~,
agaim with special and complicated accessories. From the
standpoint of Improving manufacturing procedure the third
class
of blades is the most Interesting, an it requires the most
labour.

The working part of these blades to formed by profiles of
curvo-
linear surfaces of variable cross-section over the entire
length
of the blade and there is no plane of symmetry. The cross-
aections of the working parts of the blades are at an angle to
the radial surfaces of the root. The blade contour is such
that they must be machined with reference to certain
predetermined
reference surfaces and lines. The most accurate reference surf
ce-/
would be the plane of the axial direction of the steam inlet
edg:'
and the Inner profile of the working part of the blade.
However,
from the manufacturing point of view, it is preferable to make
the reference surfaces not the inner profile of the working
part
of the blade but the plane of the root fromthe side of the
external proft-le. When this method in used the tolerances
between operations becomes very close-aind it is necessary to
introduce an additional reference basis, such as the skew faces
of the working parts of the blades. Blade mantifacture is made
more difficult and expensive because of the manufacturing

tolerances between operations with reference to the first edge
of the face relative to theFroot. Instability of the reference
base when milling the first skew edge made it necessary to
refrain
from machining two components simultaneously and to machine
each
part separately. Difficulties arose because the reference base
wandbred during machining. This is particularly important in
making screw blades. The introduction of an additional
manufacturing reference point in the form of a dowel overcame
the difficulties and made it possible to use-a constant
reference point when milling skew edges of the internal and
part
of the external surface of the working part of the blade. The
method of milling that in &4opted now that the manufacturing
reference point Is available is described. It was also possible
to simplify the design of the milling fittings. A further
important point is to reduce the amount of labour required in
manufacturing blades. Analysis of existing methods of machining
blades shows that individual machining did not meet the

requirements. This is particularly tr-ue of milling work.
Objections can be raised to multiple machining of parts to
finished dimensions where it in necessary to maintain strict
tolerances and good finish. Such objections, however, cannot be
raised to preliminary rough milling and there are many such
operations in the manufacture of blading. They include the
mi-IlIng of the inlet edges of skew and screw blades. for which
up to 16 blades may be machined at once on a horizontal milling.
machine and 8 on a vertical willing machine. A silmilar situation
arises when milling the roots of skew and screw blades.
Considerations that arise in multiple machining of parts are
discussed and it is argued that simultaneous milling of two
similar right and left handed blades in better than milling
either
separately. Improved methods of machining skew blades gave a
mean improvement in labour productivity of 36%, whilst the mean
labour-content of the blades was reduced by 24%, the
corresponding
ftgursa for screw blades being 48 and 32% respectively. There

ABSTRACT: Making use of a procedure developed in an earlier paper
(DAN BSSR v. 9,
10, 1965). the authors calculate the emission produced by a
generator-amplifier Vs-
tem with allowance for their mutual influence (i.e., the feedback
between the
generator and the amplifier)o for different parameters of the
active medium and of
the resonator. The properties of such a system are compared with
those of a system
in which*the quantum generator and the quantum amplifier are
considered separately,
so as to determine the region of parameters in which.the feedback
must be taken into
account. The calculation is based'on energy relations with
allowance for the depend-
ence of the gain of the active medium on the radiation density. A
computer (Minsk-1)
was used for the calculations. The results are presented in the
form of plots of
the emission flux against the relative reflection coefficients and
of the emitted
energy on the relative reflection coefficient. The investigation
shows that the
mutual influence of the generator and the amplifier in such a
compound system must

be taken into account if the amplifier length is shorter tbam
or equal to the length
of the driver generator, or when the amplifying section is long
but the reflection I
coefficients are close to the threshold values.. This report

that

that

ABSTRACT: The Faraday- Sucks mith method (the elastic bring method)
was
used to investigate the paramagnetic susceptibility (PS) of fer-
romagnetic alloys (Ni-Cu, Ni-Al, Ni-Si, Ni-Sn, Ni-Cr, Ni-Mn)
) in a
at temperatures above the Curie point (1200 > T >, 0
vacuum of appx. 10-3mm Hg. k
The samples investigated, pre-
pared in the form of balls of 2 mm diameter, were subjected
to annealing for 8 hours before measurement. The measure-
ments were made in a nor-uniform magnetic field produced by
means of shaped conical electromagnetic pole shoes. It is shown
that for the Ni-Al and Ni-Si alloys the negative PS is inversely
proportional to the temperature over a broad interval of temp-
Card 1/2 eratures, the magnitude of the interval being dependent
upon
137-58-1-1550
Paramagnetic Susceptibility of (cont.)
the non-ferrot-nagnetic element contents. The PS of Ni alloys in
the high
temperature range may be represented in the form of the
expression
;~ = Xk +X T where )(k is the PS that is independent of the
temperature, and
Xt is the PS varying in accordance with the Curie-Weiss law.
in the case of Ni-Cu alloys, /Yk undergoes virtually linear
diminution as the
Cu content rises, while in the case of other alloys, Xk
increases with the
proportion of the non-ferromagnetic component and is highly
dependent upon
the valence of the latter. The magnetic moments and the
Curie-Weiss con-
stant diminish as the non-ferromagnetic element increases.
Obviously, a
portion of the s-electrons of the non-ferromagnetic element
participates in
the paramagnetism described by the Curie-Weiss law, while
another part is
involved in a paramagnetism analogous to that of Pauli. The
results obtained
are in good agreement with the literature data and the theory of
s-d exchange
interaction.

ABSTRACT:
As an
introductory remark it is maintained here that
this field of
research has not been fully explored.
From a theoretical point
of view it is generally
assumed, that the paramagnetic
susceptibility of ferro-
magnetic metals in the range of
temperatures above the
ferromagnetic Curie-point T to Of is
caused by the Inner
electrons. Whereas the role of the outer
electrone is
not touched at all. TJnder certain circumstances,
how-
ever, the consideration of the effect of a-electrons
might
be of great Importance in the range of temperatures
above the
Curie-potnt, because here the peculiarities

consideration. This problem was investigated in this
paper. Taperim*ntal research was executed on pure
nickel and Its alloys with non-ferromagnetic
components: NI-Cu, NI-Znt Ni-Al, Ni-Si, Ri-Mo and
Ni-Cr in the temperature range from the Curiepoint
up to 12000C. The method by 7araday-Sucksmith was
employed for the measurement of the paramagnetic
auseeptibilltyt the investigations being conducted
in vacuum up to 12000C. The conclusions drawn here are
such, that the paramagnetic susceptibility of ferro-
magnetic alloys does not follow the law by Curie-
Weiss, at high temperatures, but the generall law

near the Curie point, and that with an increase of
the concentration of the non-ferromagnetic components
in the nickel alloy the values of the coefficients

alloy decrease. Bear the Curie point the parameter
varies with a linear relation and drops to zero at the

ABSTRACT:
Whereas for ferromagnetic metals
and alloys the paramagnetic
susceptibility 7(obeys the
Curie-Weiss (Kyuri-Veyss) law at
-high temperatures
(T*9Curie)t this is not the case with the
temperature
dependence of X in ferrites. The first theoretical
investigation of these regularities was carried out by Neel
(Refl); the results he obtained are describecl in short. They
agree well with experimental results* In the case of alloys a
considerable degree of dependence of C_ and19-values on
composition (C - Curie-Weiss constant, 9 - Curie point) was
found. Already in a previous paper the authors carried out an
experimental investigation of the temperature dependence of'X

ABSTRACT: The paramagnetic susceptibility was measured by an
apparatus based on the Faraday-Sucksmith method. The
susceptibility was measured in a -,r-acuum inthe temperature
interval between 300 and about 1 400 0K. The high
temperatures.were obta3-ned with the aid of a furnace made
of a quartz tube and heated by platinum wire. The tempera-
ture of the furnace was measured by a platinum-platinum
rhodium thermocouple. 20-40 mg specimens were investigated
in fields between 900 and 20 000 Oe. The specimens were
mixed ATi-Cd ferrites~5descrlbed by the formula
Fe 20 U - z)NIO-zCdO, where z was varied between 0 and 1.
The lerrites were obtained from the oxides Fe2o 3! Nio
and CdO, which were mixed and compressed under a pressure
of 3 t/cm 2. and then heated at 1 250 OC for three hours.

Figure I plots the reciprocal of the molar susceptibility
as a function of temperature for the specimens indicated.
As the CdO concentration increases, the dependence of
1/x on T gradually becomes linear. According to the
Neel theory the reciprocal of the susceptibility as a
function of temperature is given by Eq (1). Using
experimental values for the constants in this expression,
one can calculate the theoretical dependence of the
reciprocal susceptibility on temperature, Figure 2 gives
this dependence. The dotted curves are theoretical
and the continuous curves are experimental. The
two curves coincide in a wide temperature interval. The
area of agreement increases with increasing cadmium-oxide
conc entration. The curves do not agree near the ferro-
magnetic Curie point. Measurements were also carried out

author and Volkov (Ref.1) that 'Xk strongly depends on the
concentration of the non-ferromaXnetic component in the alloy.
It increases with this concentration, and the rate of increase is
greater for greater valencies of the non-ferromagnetic component.
In the present paper, the author reports a study of iron-nickel
alloys which has not so far been carried out from the above point
of view. Alloys containing 89.6, 80.3, 77.69 75.1, 69.o,
58-81 48.5 and 38.8 at.% Ni were Investigated. The
paramagnetic susceptibility was measured using an apparatus

on the Faraday -Sucksmith method. All the measurements were .
carried out in an argon atmosphere. FIg.1 shows the reciprocal of
the paramagnetic susceptibility as a function of temperature In

detect a small departure from linearity. In the-st two cases the
curve bends towards the temperature axis. In the first of these
two alloys this departure begins at about 10000C and in the second
at about 11000C. In other words, the linear parts of the plot of
reciprocal susceptibility versus temperature become longer for
lower concentrations of nickel, and below 77% Ni all the plots
are linear in the above temperature interval, i.e. these alloys
obey the Curie- Weiss law. The dotted lines in Fig.1 represent a

susceptibility Xk decreases with iron concentration and in
practically zero at a nickel concentration of about 75%. Beyond
this value 'Xk remains unaltered. The results obtained by the
present author suggest that Xk depends not only on the
paramagnetism of the conduction electrons and the a- d exchange
interaction, but also on the diamagnetic properties of the metal.
It follows that in studying ferromagnetic metals and alloys in the
paramagnetic region, both paramagnetic and diamagnetic properties
of these materials should.be taken into account. There are

TEXTs In order to check the correctness of Neel's hyperbolic law of
the
temperature dependence of the paramagnetic susceptibility for high
temperature, the authors studied copper-cadmium ferrites containing
cadmium ferrite of normal spinel structure. The ferrites were prepared
from Fe 20V CuO, and CdO powders which were mixed with ethyl alcohol
for
44 hr. Subsequently, the mixture was driedg siftvd, and mixed with
poly-
vinyl alcohol. Samples were pressed at 3 tons/GMZ, annealed at 10500C
for 3 hr, and slowly cooled to room temperature., The cylindrical
samples
(1-5 mm high) were examined between 300 and 1400 K, using the Faraday-
Sucksmith method (Ref- 4: Sucksmith W. Proc. Roy. Soc., AjJO, 5519
1939).

ferrites between their
respective ferromagnetic Curie points and 1400 0K- It is
seen that with
rising CdO content in the ferrite, the curves are
gradually straightened.
On the basis of experimental data, the authors determined
the constants
in Neel's law. Fig. 2 shows a comparison of the
theoretical curves, as
calculated with these constants and Neel's law, and the
experimental
ones. Finally, the authors studied the dependence of the
constants

1, 137, 1948) on
the percentual content of cadmium ferrite (CdO-Fe 20 3)
iu the composite
ferrite. They found that all the constants decrease with
increasing con-
tent of cadmium oxide. The results show that the
paramagnetic suscepti-
bility of the ferrites under discussion follows Neel's
law in the range
of high temperatuxes. LAbstracter's note: In the original

TEXT: The investigation of nickel-cadmium ferrites near the
ferromagnetic
Curie point was based on an experimental arrangement described
previously
(V. I. Chechernikov, I'Vesbu Mosk. un-ta"j ser. matem., mekbansp

fiz., khimiit no. 1, 1957). The ferrites were obtained from Fe 0 Nio

and CdO powder by pressing and sintering. In the transition range above
the ferromagnetic Curie point the magnetic susceptibility varies slowly
with the temperature in the beginning and decreases rapidly with
increas-
ing temperature afterwards. In the transition range the magnetic
susceptibility depends on the magnetic field strength. Only at high
temperatures does it depend on the temperature alone and obeys the Neel
law. The magnetization curve in the transition range can be described

TEXT: The authors report a study of ordered Fe-Al and Fe-MO
alloys, whose magnetic properties in the paramagnetic region
have not as yet been investigated. The paramagnetic susceptib-
ility was measured in the range 750 - 1 200 0C with the aid of
the Sucksmith balance; the particular alloys examined were. as
follows: 4.06; 5.98; 12.70; 19-57; 21.60; 24.70 and 28-3 at-'D

alloys was a linear function of the concentration up to
22 at.O,'D Al. Thereafter, even a small change in the~concentration
of Al gave rise to a more rapid reduction in the paramagnetic

Fe-Mo a 1 1 0 Y 5 t h e law relation between the recipro .1,
c
of the susceptibility and the absolute-temperature is again
linear for 6.1 and 5.6 at.% Mo but at 0.95 at.05, Mo and 2.119 at
Mo there is a discontinuity at 930 0C. This is ascribed to an
a y transition. Below this point the Curie-Weiss law is
found to hold. The paramagnetic Curie point of Fe-Mo alloys
decreases with concentration of Mo less rapidly than in the
case of Fc-Al alloys. The general conclusion is that the above
alloys follow the linear Curie-Weiss law at high temperatures
and the susceptibility due to conduction electrons is zero.
The magnetic properties of ordered alloys in the paramagnetic
region are very dependent on.the degree of order.~.Thus-, for
example, the paramngnetic Curie point of an alloy with 24,.7 at 50'

for the ordered state. There is also an appreciable change
in the Curie-Weiss constant and the mean number of Bohr
magnetons per atom of the alloy.
