1. The interface of austenite and martensite is somewhat straight.

2. The lath like carbide free ferrite and retained austenite has been observed by transmission electron microscope.

3. Serious mischcrystal and extremely coarse austenite grains lead to the production of this kind abnormal structure.

4. The decomposition and transformation of the retained austenite in bainite differ from that in martensite.

5. Austenite grain size of plain carbon steel and alloy steel were examined by oxidization and grain boundary etching method.

6. A new type of austenite hot working die steel added copper is presented in this paper.

7. The austenite recrystallization in every pass has been studied theoretically by computer modeling and experimentally on the bar mill at Tanggang. The calculated results agree with the measured values.

8. The influence of anomalous scattering on retained austenite determination in steel by X-ray diffraction method was investigated.

9. Abstract: The relationship between fatigue limit and prior austenite grain size has been studied by means of rotating bending fatigue tests for microalloyed case carburizing steels.

10. The change in austenite grain size of a steel with low sensitivity to weld crack was investigated via high-temperature quenching test.

11. With Al content increasing, Uniphase austenite area decreases or disappears, the liquefaction temperature becomes low, and hot-workability worsens.

12. The stability of the retained austenite is increased with decreasing finishing rolling temperature and increasing finishing rolling reduction rate, causing satisfactory TRIP effect.

13. The effect of prior microstructure, intercritical annealing and austempering was analyzed on the formation of retained austenite in the cold rolled TRIP-aided steels.

14. The microstructure of weld joint consists of austenitic matrix, columnar crystal in the form of V shape close to the fusion line and fine equiaxed austenite in the centre.

15. The hardness of the experimental steel decreases with the increase of average austenite grain size, which approximately keeps a linear relationship.

16. The results show that the microstructure of the alloys system is the compound of the acicular martensite and partial residual austenite. From the matrix, the composite carbides were precipitated.

17. Via vacuum induction furnace and metallographical analysis, the effects of RE on the grain size of the austenite and distance of the pearlite laminae of high-carbon steel for heavy rail were studied.

18. Measures should be taken to prevent the vertical snake tube from steam binding, iron oxide depositing, and austenite corrosion when superheater is cleaned.

19. There occours needle - type or M - type martensite precipitation within retained austenite.

20. In cast iron the relative quantity and the distribution of the eutectic austenite plays a more important role on the mechanical properties than the primary austenite dendrite does.

21. These phenomena probably are the reasons why the strength as well as toughness of maraging steel is not influenced markedly by the prior austenite grain size.

22. The paper discussed the fact that the content of sulphur and chlorine in the penetrant will accelerates the crack producing and expending in Austenite weld joint of Chrome-Nickel steel.

23. With the increasing of casting temperature, the dendrites grew fast, which could spheroidize and fine partial austenite with worse circularity and bigger size.

24. Deforming parameters can have remarkable effect and the austeniting temperature can determine the original austenite grain size, consequently influence the process of DIFT.

25. The carbonide in the recarburized layer is mainly M23C6. The martensitic zone is composed of dislocation martensite, twinning martensite, residual austenite and a little carbonide.

26. The material quality is ASTM A 743 M ( ZG 00 Cr 13 Ni 4 Mo ) the austenite stainless steel.

26. Sentencedict.com try its best to collect and create good sentences.

27. This paper advanced a study method that can observe plastic deformation behavior of surface layer of die cavity by showing austenite grain, size, crack morphology and propagation mode.

28. In the former case, the solute segregation in dendritical austenite more severe, and there were lumps of distortion inclusion.

29. The variation of volume fractions for static and dynamic recrystallization, and austenite grain size during rolling process are obtained by model calculation.

30. The martensitic and undissolved carbide contents continuously increase as the laser scanning speed increases while the residual austenite decreases.
