Review) PERIODICAL: Tr.Vost.-Sib. fil. AN SSSR, 1957, vyp 6, 5 - 29 ABSTRACT: The effects of heat treatment of steel on its tendency to cold-brittleness were Investigated. On the basis of literature data the conclusion is drawn that there is a connection between the tendency of steel to cold brittleness, the properties depending on the alloy structure and the changes of its phases on the one hand, and the test conditions on the other. The following steels were studied: rimmed steel St.3; St. 4 and St. 5, deoxidized by ferrosilicon; and steels marked by SA and SK. It is stated that tempering at temperatures, exceeding somewhat the upper critical point, is a heat treatment which increases the tendency of low-carbort steels to cold brittle- ness. Hardening with high tempering is considered to be a better method of Card 1/2 heat treatment, as it reduces the tendency of steel to cold brittleness and SOV/137- 59- 1-1433 Translation from: Referativnyy zhurnal , Metallurgiya; lr45q, Nr 1 188 (USSR!

The composition of the steel was: 0.120/6 C; 0.77% Mn; 0.9% Si3 0.022% S; 0.024% P; 0.84% Cr; O.5C-,o/ Ni. The influence of the heat treatment on the low temperature stability was evaluated on the basis of the chan,,,e of the critical temDerature of transformation of the steel into the brittle state durin6 impact bendinb of notched specimens, As -the critical teuperature, the upper boundary of the brittleness temperature range was chosen. In cases when the decreased in the impact stren6th ,.lias continuous the critical temperature was considered arbitrarily that temperature for which the impact strength was 40% below the respective value at room temperature.

The properties of the steel after various types of heat treatment are entered in the Table, p 54. It can ~e seen that hardening from -the optimum temperature of 920 C, followed by high tef,~tperature tempering,brought about almost no change in the low temperature stability compared to the as delivered state. 0 However, over- heating during hardeaintr by only 40 C brouEht about an increase ia the critical brittleness temperature from -90 to -50 C. In Fi~;,l the changes are graphed of the impact strength at various test temperatures for the as delivered state and after defori-nation ageing, Deformation ageing brought about a considerable reduction of the impact strength at the investigated temperatures but the coefficient of sensitivity to ageinG was 0.3,which justifies the assumption that this steel has a low sensitivity to deformation ageing.

It is recommended that this type of heat treatment should be tried in industry for certain components in cases in which a better heat treatment (hardening followed by high temperature terapering) cannot be effected for tochnoloiSical reasons or where such a treatment would be difficult to carry out. In the case of heat treatment,and particularly of welding of the steel SKhL-4, i~ is necessary to bear in mind that over-heating to 1100 C followed by cooling in air (see Fi6.2) is capable of increasing appreciably the tendency of steel to brittle fracture.

Metallev i Metallo-~*edeniye, 1959, Vol 7, Nr 1, ,pp 133-136 (USSR) ABSTRACT: A comparative stud7 Of static and dynamic bending of a number of steels has been carried out and full deformation diagrams have been constructed. A pendulum. impact testing machine of the type PSVO-1000, provided with an oscillo- graphic instrument, was used for the recording of deformation during impact testing. This impact testing machine has a maxixwxa energy of 10 kg-in. The oscillograph has a double-bean zathode tube permitting accurate re- cording of the deformation process during impact bena testing or during extension, within the co-ordinates force - path (deformation) and force - time. :6~ Fig. 1 a typical full oscillogram for an impact bend obtained for the steel St.3 is shown. The deformation diagram a6fjtc oo-cupies the middle portion of the oscillogram. Card 1/3 Below it there is a vertical line P, representing the SOV/126-7-1-19/28 Investigation of Dynamic Bonding of Steels by Deformation Diagrams force scale. The length of this line is proportional to a force of 500 kg acting on the pendulum knife. Above is situated a sine-like curve of the time scale with a period of 10-3 see. The deformation curve scale can be seen in the lower portion of the oscillogram. Its period corresponds to a shift of the pendulum knife by 2 mm. A straight line, representing the traces of the ray on its return to the initial position, is superimposed on this curve after applying the deformation scale. The essential results of tests with specimens of steel 30KhKA in various conditions, obtained by heat treatment and contact butt welding, are shown in Table 1. In Table 2 a comparison of the mechanical characteristics of a few steels, found from deformation diagrams for static and dynamic bending, is given. In Figs. 2-4 diagrams for static and dynamic bending for three types of steel, for which three character- istic different shapes of static and impact deformation curves are observed, are represented on the same scale. The authors conclude that the work of fracture during dynamic bending may be either greater or less than the work of Card 2/3 fracture during static bending~ The maximum stress SOV/126-7-1-19/26 Investigation of Dynamic Bending of Steels by Deformation Diagrams withstood by the specimen in testing is always greater during impa-ct application of the load than during its static application. The onset of yield is particularly sensitive to increase in deformation rate. No definite connection between -'.,he plasticity of the steel and the nature of the relationship between the mechanical properties during static and dynamic bending of notched specimens was observed. There are 4 figures, 2 tables and 1 Soviet reference.

It was found ttat the position of the maximum yield point (i.e. the yield point higher than predicted by theory) depends on the rate of straining in the tensile tests: at rates of 20 and 60 m/min it occurs-at a temperature of about -120OC; as the speed decreases by two orders (0.22 nmVmin) the maximum is 1 displaced 20*C in the direction of low temperatures.

In this connection, the authors investigated specimens of two metals with face-centered lattice: Ni and stainless auetenitic steel lKhl8N9Tsaturated with hydrogen (to the extent of 0.005%) at high temperatures (400-500'C) and pressure of 600 a;m.

For comparison, hydrogen-free specimens were aiinilarly tested. It is established that hydrogen enhances the straining stres- ses of these metals during every stage of deformation throughout the temperature range investigated (-200 to +909C). In the presence of hydrogen the course of the curves of the temperature dependence of deforming stresses beccMies greatly complicatel At certain temperatUres the curves display anomalies -- maxima of yield points (-100 and -20*C for N-3 gickel i.e. in the temperature range where the ffimbrittling effect of hydrogen i's the greatest) (Fig. 1). These findings are explained from the stand- f point of the dislocation theory of plastic deformation, i* es attributed to the ef-- fect of the strong elastic interaction between the diffusing R atoms and the slipping dislocations newly generated in the process of the slow deformation of the metal: the introduction of hydrogen reduces the packing-defect energy of Niand hence increases the spacing between dislocations, thus complicating the slip-a-f-dislocations,-because of the increase in the activation energy of the process. This is indicated by the increase in stress corresponding to the transition from elastic to plastic deformatto A similar pattern is observed for hydrogen-treated specimens of austenitic steel MUM. As in Ni, the anomaly effect in the steel becomes intensified with increas- ing,degree of deformation -- the maxim of the curves are the more distinct the greaft the deformation of the metal is. In fact, for steel this pattern is even more pro- nounced than for Ni; this is probably due to the special features of the crystal lat- tice structure of stainless steel, associated with the presence of atoms of alloy ale ments4 Orig. art. h": 2 figures, 3 formulas.

Findings: for the steel containing the minimal amount of manganese (0.1Z) the variation in maximum breaking stress with temperature is anomalous: at from -80 to -60*C the maximum breaking stresses are lower than at the other temperatures. By contrast, the steel containing 1.2Z Mn displays a monotonic increase in stresses with decrease in temperature.

Certain broad causal classes are distinguished, which account for the majority of material and equipment failures In the extreme nort4ern enviromnent.

These alloys were produced in an induction furnacee The critical points of the alloys were determined dilatometricalJv, while the determination of phase composition was done by carbide analvois. The specimens from each batch were dissolved anodi- cally at a current density of 0.02 - 0.03 a/cm2 in a period of 4 - 6 hours. The carbide deposit produced was subjected to analysis for iron and manganese. Iron was determined with trilon and manganese by persulfate -silver method.

The results show that the irregularities are due to small dislocation changes in the structure of the grains which take place during deformation and which the dislocation theory does not take into account.

TITLE: Hydrogen Embrittlement of Alloys of Iron With Chromium as a Function of the Temperature and the Testing Speed PERIODICAL: Flzlka metallov i metallovedeniye, io,61, vol. 12, No. 2, pp. 176 - 182 TEXT: The aim of the work was to elucidate the causes of the non-monotonous dependence of the plasticity of hydrogen- saturated metal on the test temperature. According to published views. the degree of hydrogen embrittlement depends to a considerable extent on the speed of hydrogen diffusion. Therefore, in addition to varying the temperature, the diffusion speed was influenced by using steels with differing chromium contents (0-5 and 5%). Chromium was chosen as an alloying addition in view of the fact that it reduces the diff- us�on speed of hydrogen in iron. Forged rods. 3- mm in diameter and 15 mmlong were chosen for the mechanie'al tests. These were Card 1/4 26552 Hydrogen Embrittlement .... S/126/61/012/002/001/019 E073/E335 ' annealed under conditions ensuring approximately equal grain size in both alloys. The plasticity was estimated from the contraction in tensile -tests at temperatures between +20 and -196 OC and deformation speeds between 20L~ and 0.045 mm/min. The specimens were saturated with hydrogen elec- trolytically in a molar solution of sulphuric acidi.adding sodium arsenate (3 mg arsenic per litre of solution). The hydrogen content determined by heating in vacuum at 600 0C was about 2 m1.1100 g. Doi%rn to -120 0C tests were carried out in propanol, cooled with solid carbon dioxide or liquid nitrogen. The tests were carried out in liquid nitrogen at -196 OC. A temperature minimum of the plasticity was detected which was most pronounced at low strain rates. The minimum is in the temperature range -60 to -100 0C and with decreasing rates of deformation it shifts towards the lower boundary of this temperature range. Cold brittleness was det'ected at -196 OC; the plasticity dropped sharply both for hydrogen-satil-rated I Card 2/4 -*6552 S/126/61/012/002/001/019 Hydrogen embrittlement .... E073/E335 as well as hydrogen-free specimens. Alloys with 5% chromium showed a cold-brittleness threshold at a higher temperature than alloys with 0.5% Cr. The minimum plasticity shifts towards lower temperatures with de--reasing speeds of deformation. Chromium had no influence on the hydrogen embrittlement at high rates of deformation4 a-w low rates of deformation embrittlement was more pronounced in the alloy with 5% chromium than in the alloy containing 0.5110 Cr, This difference was the more pronounced the lower the test 5peed. The presence of a minimum on the curves of contraction versus tesT temperature can be explained by the o,-currence of additional barriers impeding movement of dislocatij~ins, These additional barriers are dis- locations made immobile b-i 4~louds of hydrogen atoms. Dis- appearance of the barriers may be the consequence of displacement of dislocations that have been 5iopped earlier, together with hydrogen clouds surrounding them, There are 5 figures, I table and 20 references-, 9 Soviet and 11 non-Soviet, rhe four la-tes-, English--language references quoted are'.

The brittleness was taken as the ratio of the difference between the reduction in cross sectional area of a test piece in the original and hydrogenated states to the original value. The following methods of hydrogenation were used i 1) for 110 hourt; in gas at 500"C and 300 atm pressure (brittleness 28 to 60%, 30A to 35 ml hydrogen/ 100 g),, 2) for 14 hours (giving limiting hydrogen content) Card 1/3 20211 s/i26/61/011/002/007/025 Hydrogen Embrittleittent Ell.l/E452 electrolytically (brittleness 0 to 2%. 18.5 to 20 rnl hydrogen/ 100 g); 3) for 14 hours electrolyt:t.cally, followed by copper plating and annealing at 450 to 500)C to cause hydrogen diffusion (10 to 1276, 9.3 to .1.0 ml/100 9); 4) 300 to 350 hours electrolytically (18 to 20%, 15 to !6.3 milloo g)j 5) 800 hours electrolytically (50 to 54%, 29.7 to 30 m1/100 9)~ Decreases in plasticity are particularly marked at low deformation speeds. The tensile strength 15 hardly affected, Treatment 1 gave the highest brittleness; 2 had little effect, the hydrogen being confined to the surface, Treatment 3 allowed diffusion of hydrogen into the depth of the specimen but much hydrogen was lost in spite of the copper coating,. With longer hydrogenation with periodical replacement of electrolyte (treatment 3) better hydrogen penetration was obtained and it was noticed that the resulting specimens became more sensitive to hydrogen embrittle- ment at a given deformation speed Ihe higher their hydrogen content. To chec'k this an even longer period, 800 hours, was used~ Further tensile tests at 0,175 mm/min deformation speed were made at 20, 50, 70 and 100*C on specimens hydrogenated for Card 2/3 Hydrogen EmbrIttlement 20211 S/126/61/011/002/007/025 E111/E452 200 hours, specimens for the two Iiighest temperatures being copper plated (0.05 mill thick layer) to reduce hydrogen loss: the relative decrease in cross-sectional area falls almost linearly from about 71% at 200C to about 66 at 1000C.
