摘要：
The hot deformation behavior of 0.1C-18Cr-1Al-1Si ferritic heat resistant stainless steel has been investigated in the temperature range of 900-1100 degrees C and the strain rate range of 0.01-1 s(1)1 employing compressive tests. The obtained results have shown that the volume fraction and average size of the AlN phases and (Cr,Fe)(23)C-6 carbides decrease with increasing strain rate. The deformation activation energy is calculated as 332.306 kJ.mol(-1). Based on the analysis of processing map and microstructure, the optimum processing domain for hot deformation is confirmed as the temperature range of 1045-1100 degrees C and strain rate range of 0.06-1 s(-1).
