Dynamic recrystallization during hot rolling
Web1 day ago · In Ni–Cr 800H Alloy, continuous Cr 23 C 6 at GBs could also restrain the occurrence of dynamic recrystallization during hot–rolling in the temperature range of 850–950 °C [18]. There is no M 23 C 6 at GBs in the raw material in Fig. 1. Therefore, the M 23 C 6 precipitates observed in WebThe dynamic, static and metadynamic recrystallization behavior of austenitic stainless steel during hot rolling was analyzed. In this approach, each of those recrystallization behaviors is described by appropriate kinetics equations. The critical strain for dynamic recrystallization was determined so that a distinction could be made between static and …
