TEXT: The steels 5 and 30 3A (3OKhNZA were subjected to the fatigue
test in plain bending at the Hy-( -) mach-in--e77.52 mm diameter of the specimens)
and at machines specially designed for this test (12.5, 20, 30 diameter of the
specimens). The statical tensile strength limits of the chcsen materials were:
for the steel 45 equal to 65 kg/mm2, and for the steel 11OKhNZA equal to 114 kg/

regions of the specimens were chosen. Preliminary overstresaing the spocimens
with symmetric bending oyclen was performed before the fatigue testo. '111 C.

TITLE: Effect of annealing and combined treatment on the mechanical properties of the
alloy KhN77TYuR
-SOURCE: Metallovedenlye i termicheskaya obrabotka metallov no. 1, 1904, 14-19
TOPIC TAGS: annealing, electroplating, alloy mechanical property, turbine blade,
KhN7-7TYuR alloy, alloy hardness
ABSTRACT: In order to explain the cracking of turbine blades during their use, the
authors studied the effects of annealing in air, N113, N, and Ar on the alloy XbN77TYuR
and the effects of heat treatment and electroplating on the mechanical properties of parts
manufactured from this alloy. The finished parts, with or without clectropolishing, were
annealed in air at 750 C for 8 hours, or in dissociated NH , N, or argon at 850 C for 2
hours. Parts treated in a neutral atmosphere were annea?ed and aged at 700 C for 7 hours.
The mechanical properties of the parts were evaluated by determining their microhard-
ness, wear resistance, delayed failure, ductility, and impact toughness. It was found that
the microhardness was decreased to some extent in all tested media and conditions. The
miorohardness was more markedly decreased on annealing at 860 C for 2 hours than by

annealing at 750 C for 8 hours. The mechanical properties of the tested alloys were in~
creased by annealing and electropolishing, the best results being obtained by annealing in
an argon atmosphere. A positive effect of electropolishing on the delayed failure and wear
resistance was also demonstrated. It is concluded that annealing of blades made of alloy
KhN77TYuR may be carried out in air at 750 C for 8 hours. Optimal mechanical properties
are obtained, however, by anneaUng in an argon atmosphere after electropolishing. Orig.

TITLEs The Scale Pffed in Overloading Alloyed Steel
PERIODICAL-. Nauchn. zap. Odessk, politekhn. in-t 1959, Vol 16, pp 252-265
TEXT. The authors investigated the effect of preliminary cyclic load on
metal creep depending on the absolute dimensions of the specimen, The,)n-
vestigatlon was carried out on preliminary normalized 30XH3A (30KhN3A)Nalloyed
steel specimens of 7,52; 12.5; 20 and 27 mm in diameter, The results were com-
pared to those obtained previously from 145 steel tests. It was established that
the absolute dimensions represented a factor which affected strongly the fatigue
limit of the ma'Leria-1 and i-,s overload strength. It is shown that the overload
resistance of steel grows with increased absolute dimensions: the cyc-l1c
durability, under similar relative overload, increases with a larger diameter of
the specimens. It is assumed that the regularities determined may in principle
also be applied to other structural steel grades,

The data are not sufficient for final recommendations, but it is evident that
small-diameter specimens of high-qualitY 30IM3A e~lloy steel had highest sensitiv-
Ity to overload, ard the sensitivity decreased with increasing specimen diameter.
This observation ft.Ily'mbLtohes data obtained by S. Villips and R. Haywood (Ref - 51

19571. The m-factor range corresponded to the range indicated by Res6etov. The
effect of the stress concentrator was clear - it made the m-factor value practical-
ly equal for two diffierent steel grades, and m varied in a narrower range. It is
evident that the averaged values employed presently for calculations are not ade-
quate for today accuracy requiTements. There is I figures and 5 references: 5 So-

AWTRACT: 7ic paAr is devoted to a general discussion of the problems involved in
development of electroluminescant display screens (matrix screens) and electro-
luminescent converters of visible and x-ray images. In conjunction with the screens
it is indicated that current rasearch is aimed at increasing the peak brightness of
electroluminescent phosphors (important because the average viewing brightness Is a
function of thi maximum brightness multiplied by the excitation time of a screen
element and divided by the interval: between successive activations) and development of
means for realization of infonnation storage on or for the screen. Approaches to
embancement of brightness are improvement of the composition of phosphors and electro- r
forming, which Involves application of an no or dc potential to the electroluminescent

Abstract The influence of the ionization of air on the dispersion phase
of a natural aerocol-lold was studied. Ultraviolet and x-rays
and(--particles served as sources of ionization. The irraiia-
tion of air was carried out in chambers, the volume of whicu
was from 0.8 to 2 cut.m. The concentration of particles was
determined ultramicroscopically in a flow. At the concentra-
tion of up to 105 or 107 pairs of ions per -ub-cm in ordinary
air with the relative humidity up to 100%, the concentration
of ultrandcroscopic particles increased 3 to 4 times, and the
number of' nuclei of -,-ondensation increased over 10 times. The
concentre.tion of particles rises together with the Irradiation
duration and the ionization degree; the riize of p&rtic-'es in-
creases together with the zoncentration rise.

Ultraviolet rays, Y rays, ani beta-particlev were used as a source
for the lonization of atmosrheric air. About 1,NO tests were perforred
showing the influence of ionization of air on the concentration of ultra-
microscopic particles in moist air, the influence of duration of ioniza-
tion (irradiation) of air on the concentration of ultramicroscopic par-
ticles, the influence of ionization of air on the maxin=n radius of ul-
tramicroscopic particles, the influence of the degree of ionization of
air by X rays on the concentration of ultramicroscopic particles, and the
influence of ionization on the concentration of condensation nuclei.
The results prove that an increase in the ionization of the dis-
persing medium increases the concentration of the particles of the dis-
persed phase of aericolloids. At concentrations ranging from lob to 107
ion pairs per ci~bic centimeter in ncrmal air with a relative humidity
not exceeding 100% the concentration of ultramicroscopic particles is in-
creased threefold to fourfold and the number of condensation nuclei Is
more than ten times greater.

according to Soviet standards) at different temporature.,3, 15-3:) minutes
being necessary for the temporature adjustment of the sample according to
Epshteyn (Ref. 1), and at room temperature under the action of various
solvents. According to measurements made by the 11olzforschungsinstitut
Bratislava (Wood Research Institute Brati,-,,-lava) on wood specimens,
measured shear !jtrengt,"l slightly drop after
aging of specimens. The bending strength was studied with metal adhesives
by the "bend test" at room temperature: the specimen was fixed on two
supports (38 mm apart), loaded over the Joint by a wedge (radius 6 mm),

obtained by Soviet standards. A table gives the teat reaulto for 19
adhesives: tensile and shear strength (kg/cm2): at room temperature:
140-315, at 630C and 930C, respectively: 11.3-408, at -750C and -560C,
respectively: 108-381; tensile and shear strength after the action of
sodium chloride solution (30 times 24 hours): 170-2~)6, of drinking water
(30 times 24 hours): 145-393, of h draulic liquid (',' timea 24 hours):
125-363, of jet fuel (7 times 24 h~: 122-346, of ethanol with benzine

125-312, of chromosulfuric acid (700c, 10 min): 102-'~19. DiaKrams show
the effect of temperature on the '' tensile and shear ntrength: it rises
slowly from -800C to a maximum at about 800C, ther, it, drops until the
strength has attained zero at about 2400C. There are 1~ f.

JILRIODICAL- Strojlfrenstv~, v.11 no 11 1961, 848-856
TEXT- A number of Czechoslovak adhesives based on epoxy-
resins, were tested and compared with foreign products with respect
to strength properties in shear by tension loading Methods of
testing and preparation of specimens and test joints are described
,~,ince testn included also frost and heat resistance of the
adhesives, the testing machine was provided with appropriate
heating and cooling arrangements. Aluminium allay sheet (accordinz
to the Czechoslovak Standard Specification 42 4253,66) was employtd
for the test- Specimens and methods of testing conformed to
Czechoslovak Standard Specifications 66 8510, said to be identital
with ASTMD1002-49T, Results of the following tests are summarized
in tab e9 and graphs, i e 1) Tabulation of shear strength tests
(k9/cm ) of nine Czechoslovak adhesives, carried out at room
temperature, at 83 # 2'C and at -75 to -80'c Curing conditions
