iABSTRACT: Measurements of internal friction were made in an WF MIS relaxation

ivery carefully prepared and treated, and (after measurements) they were chemically '
*1analyzed and the lattice constants and structures were determined. By means of thei
internal-friction measurements and determination of elastic aftereffects, the
authors observed the relaxation affect in homogeneous solid replacement solutions

the solid-solution lattice deformation. This theorem is based on
the theory of LeClaire and Lommer concerning the Zener relaxation
effect as a result of the change in the degree of the short-range
order. The results are compared with the experimental values and
temperature and concentration dependences of the degree of relaxa-
tion in these systems are plotted. It is concluded that a theory
of LeClaire and ;-s more consistent in all respects than the
Zener concept of reorientation of pairs of dissolved atoms. The
relaxation effect proposed by LeClaire and Lommer is refiiie,'. I)y
introducing not only the change in the energy of interactio~i of the
atoms during the relaxation but also the energy of the elaFti7 de-
formation of the lattice. The formula derived for the deg.e(- of
relaxation takes into account the changes in the energy of i,kterac-
tion of the atoms and the energy of the elastic deformati)n. The
contributions from both types of energy are evaluated separi,tely.
The temperature dependence and the concentration dependence of the
degree of relaxation were investigated by measuring the internal

TITLE: The Nature of the Maximum of Internal Friction in
Steel After Thermal Treatment
PERIODICAL: Fizika metallov i metallovedeniye, 1960. Vol. 10.
No. 2, pp 285 - 290
TEXT: Experiments were carried out on three steels - WA, U9A
and U12A - the compositions of which are given in Table 1.
Measurements of internal friction were taken on ajelaxator at
a frequency of I cps. Results for two steels are given in
Fig. 1, where the internal friction is plotted against tempera-
ture. The curves contain the usual maxima at 200 0C. The curves
with the higher peaks are for the steel with the greater amount
of carbon. The absolute values of the peaks are given in
Table 2. Working in the cold leads to a decrease in the value
of the peak corresponding to the decrease in the retained quantity
of austenite. Fig. 2 shows the internal friction - temperature
curves for U9A steel after quenching from Bub-critical temperatures
(720 OC and 670 OC). A low maximum is obtained at 200 0C, much
less than that0after quenching from the austenitic condition.
Thus, the 200 C peak can be explained by two phenomena taking

place simultaneously: diffusion of carbon atoms in the retained
austenitA and migration of carbon atoms to the dislocation regions
forming on account of the martensitic transformation and thermal
stresses. Further experiments were carried out on armco iron
containing 0.0190/~ carbon after 255'0' and 759' deformation, Fig. 3
shows the curves obtained. Deformation of 25% leads to two peaks
at 40 and 200 0C. 751". deformation gives one peak at 2000C. The
disappearance of the first peak can be explained by migration of
carbon atoms in the alpha-iron to more energetic positions - in
dislocations. The peak at 200 0C is much lower than for quenched
steels because of the smaller amount of austenite

specimens were tempered at 350 - 6',0 (with 500 intervals) with 2 hours
soaking. Half of these specimens w;re rapid-cooled (in water), half of them
slowly (in the furnace). Other specimens were tempered at 6500, oooled
rapidly (producing a tough state), then part of them was embrittled by hold-
ing at 5000 for 12 hours. Rods cf annealed steel 6 mm in diameter were
drawn with intermittent annealin6s (6500, 1 hr) in a vacuum furrace to 0.8
mm diameter, and this wire annealed in a vacuum at 8500C for 2 hrs. The
0.6 mm diameter and 1.15 mm long specimens were heated at Ac3+500 (5 min)
inside austenite steel pipes, and cooled in oil. This quenching method pro-
tected the specimens from decarbonizing. The internal friction and the
shear modulus were measured simultaneously in a fNI-MV-'_(RKF-MIS) vacuum

ABSTRACT: An internal friction study was made of the effects of C, OW and N;~ additions
in molybdenum. The temperature dependence of internal friction ~as 'measurdVI-11 a vacu-
izzi, on samples of 1 iiim width and 0.35 mm thickness. Oscillation frequencies rangea from
0.5 to 2.1. cps. Quenched samples exhibited a wide internal friction peak, spread over
the range 60-4000C, the height of which increased linearly as a function of quenching
temperature due to the higher solubilities of the interstitial atoms. The concentra-
tion ratio C/C max for C, N2 and 02 corresponded with the internal friction ratio Q 1/
/(~' . The peak itself consisted of three components--I, II, 111--a high central por-

tion (II) and two neighboring plateaus (1, 111). The related activation energies as
determined by the Wert-Harx method were 26, 32, and 39 Kcal/mol for 1, 11 and III ne -
spectively. Component M was associated with carbon since it vanished after quenching
from 10000C, and the concentration of carbon in solid solution is negligible below
12000C. The central component II may have been caused by oxygen since oxygen is the
most soluble interstitial in molybdenum; also Q-1/ I correlated best with 02/02
'Qx
max
Canponent I was probably caused by nitrogen. The activation energy for nitrogen di-ffu-
sion in molybdenum was previously determined by Hartley and Wilson to be 25.1 t 2.7
Kcal/mol. The peaks and the low temperature background decreased in magnitude after
tempering at 6000C for 30 min, or in quenched sTples after annealing in hy~drogen at
16000C. Deformation of vacuum annealed samples pushed the high temperature side toward
the left, either as a rwsult of the breakaway of dislocations from Cottrell atmospheres,
or because of localizee differences in deformation conditions. Orig. art. has: 6

ABSTRACT: Hydrogenatioii-.Iesulphurlsation over oxide catalysts at
10 70 atms pressure of hydro-en, and temperatures cf
360 4200C Is the most effpctive method for purifying
petroleum products. The authors investi-ated the de-
sulphurisation and lehydro-enation activity of aluminium-
cobalt-molybdenum catal7st and defined its optimum
chemical composition. Diesel fuel from Romashkinsk
Petroleum was used in these tests. The composition of
the diesel fuel Is tabulated. Samples of the catalysts
were prepared accordin_- to a pro-less similar to that
used in industry. ',Yet aluminium oxide was suspended

the catalyst contained 1.9,~p CoO and 18.14 L!c03 which
corresponds to a molar ratio CoO:MoOjoeq~aj to 1:5.

Conference on Zoolites, hold In Leningrad 16 throup 19 March 1961
at the Leningrad Technological Institute Imeni Lensovet, and is
purportedly the first monograph on thin subject. The reports are
grouped Into 3 subject areast 1) theoretical problwas of adsorp-
tion on various typos or z*Dlitos and nothoda for their Inveotl-
gatlon, 2) the production of secolltes, " 3) application of
zoolltes. No personalities are montioned. References follow In-
