Abstract High temperature solution treatment of ECAPed samples of austenitic stainless steel ingot was studied experimentally , and both microstructure and properties of ECAP + solution samples were compared with that of forging + solid solution samples, the results show that full recrystallized microstructure of samples ECAPed at room and elevated temperature was obtained after solid solution at 1150 ℃.The increase of ECAP pass number has no effect on grain size, however homogeneity can be improved.After ECAP + solution treatment, both microstructure and properties of cast austenitic stainless steel samples are as same as that of forging + solution ones, showing that ECAP is a suitable method to replace blooming.
