Hot deformation of 15-5 PH stainless steel
چکیده انگلیسی

The hot deformation behavior of 15-5 PH stainless steel has been studied using hot compression tests over the temperature range of 900–1150 °C and strain rates varying between 0.001 and 0.5 s−1. The results showed that dynamic recrystallization is the main softening mechanism when the alloy deformed at imposed temperature and strain rate region. Strain rate sensitivity of the material was evaluated in all the deformation conditions and the obtained values were used to calculate the apparent activation energy. Based on the flow stress data obtained as a function of temperature and strain rate, power dissipation map and instability map for hot working have been developed.
