Abstract
In this research, the hot working behavior of 13.5Cr6Al0.3C high aluminum mild steel was investigated. This steel with 3% Al by weight has a higher SFE than other stainless steels, for this reason, the test of the hot pressure behavior of this steel and its microstructural changes, including recovery and recrystallization mechanisms, were investigated. According to the prediction of JMatPro software, this steel is ferritic at all temperatures and carbide deposits are formed in it. Accordingly, the hot pressure test was performed at temperatures of 850, 900, 950 and 1000 C at strain rates of 1, 0.1, 0.01 and 0.001-s. After calculating the fundamental relations of hyperbolic sine, the activation energy of silane stress for this steel was calculated as 379.84 kJ/mol. Also, the Zener-Holman equation was calculated and based on the process map of this steel, a temperature of 950°C and a strain rate of 0.1-s were reported to have the lowest activation energy.
