Abstract

The hot deformation behavior of 0.1C-18Cr-1Al-1Si ferritic heat resistant stainless steel has been investigated in the temperature range of 9001100°C and the strain rate range of 0.011 s¹¹ employing compressive tests. The obtained results have shown that the volume fraction and average size of the AlN phases and (Cr,Fe)₂₃C₆ carbides decrease with increasing strain rate. The deformation activation energy is calculated as 332.306 kJ·mol¹¹. Based on the analysis of processing map and microstructure, the optimum processing domain for hot deformation is confirmed as the temperature range of 10451100°C and strain rate range of 0.061s¹¹
