Abstract:
In this research the effect of initial microstructure on hot deformation behavior in terms of Ferrite-to-Austenite ratios is studied. Two types of stainless steels C۱ and C۲ were homogenizing heat-treated and deformed under hot compression examinations at temperatures ۹۰۰ºC and ۱۱۰۰ºC at strain rate of ۰.۱s-۱. The results showed that the flow stress levels of specimens are strongly related to deformation parameters and initial microstructures of steels. Moreover, during cooling from ۱۳۵۰ºC to the deformation temperature, flow stress level increased for both samples because of increment in austenite content.
