1.The high wearing resistance of the samples after hydrocooling and air cooling was partially attributed to martensite transformation and work-hardening.
2.It was reported that the detwinning stress in martensite of Ti-Ni alloys increases with increasing annealing temperature, but the reason for such a strange behavior has remained unclear.
3.It holds that main causes promoting crack on martensite stainless steel are gross martensite and crystal boundary carburet and secondary phase distributed along crystal boundary.
