Abstract: (5754 Views)
The effects of carbon content on the dynamic and static softening mechanisms of Ti microalloy steels were investigated both in ferrite and austenite regions.
The results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. This is due to the Ti(CN) and TiC precipitates and also the free carbon content. In the ferrite region, the main obstacles for dynamic recrystallization are interstitial elements such as C and N. The interrupted compression tests also showed that increasing temperature leads to the increasing rate of static recovery and recrystallization in both ferrite and austenite regions.
