Z/034/60/000/07/004/029 E073/E535 On the Problem of Intercrystallite Corrosion of Austenitic, Cr-N! Steels Containing 24% Cr and 19% Ni grain boundaries may drop below the passivation level in the surface layer as a result of rejection of chromium carbides, which provides a basis for inter- crystallite corrosion of this steel. This disproves the theory of intercrystallite corrosion being due to internal stresses, not only for the here investigated steel but also for the steel lCrl8NigTi(Nb), for which it was proved earlier (Refs 1 and 2) that artificially generated segregates at the grain boundaries are chromium carbides Cr C and not titanium or niobium OK carbides. J. PhiliHr~ and H. Bizouard (Ref 15) have established directly by means of X-ray spectral analysis a drop in the chromium content of austenite during rejection of chromium carbides in stainless steels. They used a micro-analyser with an electron probe (Refl6) which permits making an accurate quantitative analysis Card 4/5 and a local identification of the structural lattice Z/034/60/000/07/oo4/o29 E073/E535 On the Problem of Intercrystallite Corrosion of Austenitic, Cr-Ni Steels Containing 24% Cr and 19% Ni within a volume of 1 cubic micron. Such local analysis proved unequivocally the fact that the grain boundaries of stainless steel are impoverished in chromium in the neighbourhood of rejected carbides.

In the experiments two titanium stabilized steels with Cr content of about 18% and Ni content of about 9.5% with Ti:C ratios of about lOtl and-4:1, and one non- stabilized steel with a lower carbon content were chosen. The chemical compositions of the three steels are given in Table 1. All the steels were subjected to the same heat treatment, consisting of heating for one hour at 1250 OC followed by quenching in water and tempering for durations of 5 minutes to 72 hours at temperatures between 550 and 850 OC. The results of the work have shown that the rejection of chromium carbide takes place at first in the form of two-dimensional dendrites which grow to certain Card 1/2 1'1~ Structure and Distribution of Austenitic Steels 81877 S/129/60/000/08/004/009 F-073/E135 Secondary Phases in Stainless critical dimensions and then become transformed into more stable and crystallographically more perfect shapes. The rejection of thermodynamically more stable titanium carbide takes place at high temperatures due to the low diffusion speed of the titanium. The character of the titanium carbides differs from that of chromium carbides and the TiC rejections in the structure of titanium- stabilized steels consist of very highly dispersed particles of steel which can only be detected by means of electron microscope techniques, Fig 10 shows a photo of the dispersed rejections from one of the steels (X 12 000). An electron diffraction pattern of- the same rejections is reproduced in Fig 11. There are 11 figures, 2 tables and 8 references: 4 German, 3 Czech and 1 Soviet.

Kehsin-Kuo (Ref. 6) are discussed in some detail and it is stated that detailed Soviet results confirm the results obtained by the team of the authors of this paper. The main difference between the results consists of the fact that Kehsin-Kuo has not detected in any of the investigated cases the intermetallic phase Fe 2W. The fact that Laves phases were detected in Czech steels and were not detected in the steels investigat.ed-by Kehsin-Kuo Card 1/4 85191 Z/034/60/000/011/004/009 E073/E335 On the Problem of Precipitation of Laves Phases in Modified 12% Chromium Steels 6 is explained by Cadek (Ref. 9), primarily by -the presence of V, pointing out the low value of the atomary ratios W:C and Mo:C in Czech steels. According to him, the condition for precipitation of Laves phases in Mo steels is that the Mo:C ratio should be above 5. The authors of this paper do not agree with the view of 6adek; they haveproved the presence of the Laves phase Fe 2W in a Czech vanadium-free steel OD - Table 1). They believe that even in Co-containing steels which have a homogeneous structure in the heat-treated state, the presence of V is not a necessary condition for the precipitation of the Laves phase but Co probably has a catalytic effect on separating out Fe 2W in the case of a W:C ratio which is less than the critical value. For verifying these views, the authors have carried out experiments with two melts, one a 12% Cr-Mo steel and the other a 12% Cr-CD-W steel with the following chemical compositions: Steel M - C 0.20%, Si 0.47%, mn o.48%, P o.oA%, s o.o3o%,,, Cr 11.9%, Ni 0.42%, Mo 1.84%; Card 2A 85191 Z/034/60/000/011/004/009 E073/E335 On the Problem of Precipitation of Laves Phases in Modified 12110 Chromium Steels Steel C C 0.28%, Si 0.250 , mn o.16901, P o.ol-og.1, S 0.o29%, 50 Cr 11.56oo, Ni 0.179'0, W 3.42%, Co 5.50%. The steels were smelted in a 40 lcg induction furnace, cast into '-ingots which were then annealed and forged into ilk x 14 mm rods and heat-treated byoquenching from 1 050 OC in oil, followed by -tempering from 770 C (Steel M) and 670 OC (Steel C) with cooling in air. After this heat treatment a number of specimens were subsequently annealed at 650, 700 and 800 oC for durations of 100, 500 and 1 500 hours. Investigations were carried out by optical and electron microscope studies and analysis of the precipitates. Microstructural and X-ray analysis of the specintens led to the following conclusions. 1) Even in the absence of V precipitation of the Laves phase Fe2W can occur in 12% Cr-Mo steels with a low atomary MotC ratio, in which the microstructure in the heat-treated state is heterogeneous. This supports the view of the authors that in such cases concentration differences between the ferritic and Card 5/4 85191 Z/034/60/000/011/004/009 E073/E335 On the Problem of Precipitation of Laves Phases in Modified 120,10 Chromium Steels austenItic (sorbttlc) phases have a decisive importance. 2) In the case of 121,11*' Cr-W steels, which have a high Co content and a homogeneous structure in the heat-treated state, precipitation of the Laves phase Fe2W may occur in the case of low atomary W:C ratios, even in the absence of V; this cafirms the view of the authors that in such a case the separation of the intermetallide Fe W may be due to the catalytic effect of Co.

Vodsed"alek and L. Mek, stroilrenstvl' 9 (1959) No.6, P-439), where it was stated that, due to its excellent anti-creep and relaxation properties, it is suitable for extensive use for machine parts operating at 650 to 6750C and up to'- 7000C for less mechanically stressed components. The development of this steel has reached a stage when it can be used for blades of steam turbines. Due to its exceptionally high resistance to relaxation, it is one of the best steels for bolts. In later work (Ref,2: L.6:L'Zvek: Candidate dissertation, SV6MT,Prague and Ref-3: J, Voborvil: Candidate dissertation, SV6MT, Prague) Card 1/10 24647 Influence of structural changes ... z/o34/61/000/009/001/002 E073/E535 attention was paid to structural changes which occur in this material during heat treatment and in operation. The composition of the steel is 35% Ni, 15% Cr and 3% W; hardenability is achieved by adding about 1.5% Ti and also Al. Equilibrium diagrams for this type of steel are not available. The structural conditions in this steel can be judged only on the basis of simplified ternary diagrams Ni-Cr-Ti, Ni-Cr-Al, Ni-Ti-Al and pseudo-ternary diagrams Ni-Cr-Ti-Al plotted by Taylor and Floyd for Nimonic type alloys. The steel under consideration differs from these alloys inasmuch as a part of the chromium and a larger part of the nickel is substituted by iron with a small quantity of W. It could be anticipated that for the steel AKRN the structural relations are slm�lar to those pertaining to Ni-Cr-Ti-Al Nimonic type alloys. This means that, in addition to the y-solid solution matrix, the phase y' with the basic composition Ni Al with a face-centered cubic lattice may be present, the paraaeter of which differs only slightly from that of the y-solid solution. This phase is capable of dissolving titanium and about 3/5ths of the Al atoms can be substituted by Ti atoms. This substitution increases the Card 2/ 10 24647 Influence of structural changes ... Z/034/61/000/009/001/002 E073/E535 difference between the lattice parameters of the y' and the y phases, which has a favourable influence on the resistance to creep of the alloy after hardening. It was found that the longest time to fracture is obtained for specimens subjected to solution annealing at 1150% for two hours. After rapid cooling from this temperature, a saturated y-solid solution is obtained which contains TiC carbides that did not dissolve during the annealing. The steel has a low hardness,strength and yield point. and a high elongation, ccrAraction and impact strength. The second stage of heat treatment is precipitation annealing, during which considerable changes occur in the hardness.depending on the temperature and duration of this annealing. Fig.1 shows the hardening curves of a heat containing 2.15% Ti (hardness H VS. annealing time, hours); the solution annealing was effectel at 11500C for two hours, followed by quenching in vater. The maximum hardness for this heat was 320 H Fig.2 shows the hardening curves of alloys with various Ktaniumi contents after a precipitation hardening time of 10 hours (hardness H.

Z/034/61/000/009/001/002 E073/E535 shows the strenglh and yield point of a heat with 2.15% Ti (a kt'apt ,kg/mm vs. annealing time, hours; solution annealing same as In previous figures). It can be seen that as a result of the preciFitation hardening the hardness increases 2from 62 to 108 kg/mm and the yield point from 25 to 70 kg/mm . The maxima roughly correspond to the maxima of the hardness curves. The elongation and contraction decrease in accordance with increasing strength. Over-ageing, which occurs after 100 hours at 7000C, is characterized by the yield point not decreasing further and the contraction increasing . The position is similar for ageing at 800'C. The impact strength decreases at all temperatures from the very beginning of the precipitation annealing and its initial decrease will be the higher the higher the annealing temperature. This decrease shows that there are local reactions at the grain boundaries. Detailed information is given on the structural changes after precipitation hardening. The individual phases were investigated by X-ray analysis using monochromatic CrKa radiation. Analysis of the finest phases were made urith electron diffraction methods on particles caught on the extraction replicas. Card 4/ 10 24(jO Influence of structural changes ... Z/034/61/000/(109/001/002 E073/E535 In some cases electron diffraction analysis of fine pairticles was carried out directly at the surface of the metallographic specimens. These investigations revealed several processes in the structure, namely, precipitation of chromium carbides at the grain boundaries, precipitation of fibrous titanium carbide, precipitation of intermetallic compounds. Interesting recrystall- ization phenomena were observed if ageing at 8000C extended over a long period. A K-structure was detected by means of' differential thermal analysis. During the first period of the precipitation hardening, when the hardness, strength and yield point increase, no change can be detected in the structure even by electron microscopes with a resolution power of about 100 A. The main hardening effect is attributed to the precipitation of the y'-phase - Ni 3(Al,Ti). It was found difficult to determine the importanc e of Ti(C,N) precipitate in the hardening process but no particular role is attributed to it. The hardening process continues during operation and the maximum hardness is achieved sooner or later, depending on the temperature and the titanium content. In addition to the hardness, the strength and Card 5/10 24b47 Influence of structural changes Z/034/61/000/009/001/002 E073/E535 yield point also increase. At an operating temperature of 6500C the steel under investigation maintains a maximum hardness, strength and yield point without any appreciable change in the elongation and contraction for over 10000 hrs Fig.14 shows the properties of this steel as a function of the annealing time at 650*C.

There is a slight drop in the impact strength. indicating structural changes at this temperature (65000v i.e. primarily continuing precipitation at the grain boundaries. At higher temperatures over-ageing occurs which results in reduced resistance to strain; at 7000C a drop in hardness occurred after 100 hours. Over-heating, following by precipitation hardening without solution annealing, reduces the service life its compared to material which has not been over-heated. The results lead to the following conclusionsa Card 6/io 24647 Influence of structural changes ... Z/034/61/000/009/001/002 E073/E535 Structural and mechanical tests indicate that hardening of this steel is primarily due to precipitation of the y'-phase, the composition of which is Ni (Ti.Al). The second intermetallic phase I of the compositign Ni Ti appears in the structure during the advanced stage of ove~-ageing and its occurrence does not manifest itself on the curves expressing resistance to deformation. In the early stages of precipitation, particles of fibrous carbide appear, for instance, the carbonitride Ti(C,N) which precipitates primarily in titanium enriched zones. At the grain boundaries local precipitation of the chromium carbide Cr7C3 will occur. Tests with over-heated specimens again confirmed the fact that high hardness of hardenable alloys does not guarantee a high resistance to creep. Over-heated specimens, which were again hardened without solution annealing, reached a hardness equal to those of specimens which had been over-heated but their creep strength was low, since,as a result o1'' this process.the solid solution matrix was impoverished of its hardening component. Due to its high structural stability, this steel is suitable for components intended to operate at about 6500C. Acknowledgments are expressed to Engineer P.

Heats containing more than 5% of ferrites showed surface defects; high content of ferrites, appears to be the major cause of reduced. itorkability, even if it is not the only one. The effect of the dissolving of TiC carbides upon the precipitation of Cr carbides in coherent layers along the grain boundaries of ferrites resulting in defeets that app W, during rolling is described.

Conclusions: 1. 7-1,Tot u diagnosed infarctions are more frequent in the age above 70 years. Usually slight, atypical,or no complaints are recorded. 2. The majority of nond-Jagnosed infarctions are due to atherosclerotic obliteration of the coronary artery without thrombosis. 3.

Prague, Casopis Lekaru Ceskych, Vol 105, No 42, 21 Oct 66, pp 1155 - 1156 Abstract: The increased transaminase level is not specific for a defiRlite disease- 40 patients suffering from emphysema with chronic bronchitis were examined. Increased levels of GOT and GPT were found only in decompensated patients, and less frequently than is indicated in literature. The normalization of the values takes usually 3-4 days. The finding of increai3ed GOT and GPT levels may be used for a differentiation of a i5imultaneous car- diac infarot. The actual causes of the increa;3ed values of GOT and GPT could not be determined unequivocally. 1 Table, 3 Western, 3 Czech referenees. 1/1 CZECHOSLOVAKIA POPUTHAR9 L.; ROSIVAL, F.; JEZEK Z ; IfEBELKA, M.; Veterinary Faculty, Chair of Infectious Dist-a-sel-9'..
