The effects of hot or cold deformation and thermal history on sigma phase precipitation in a 25Cr-7Ni-3Mo and a 23Cr-6Ni steels with ferrite/austenite ( alpha / gamma ) duplex structure have been studied. Precipitation is enhanced by hot work or thermal strain as well as cold work. The enhancing effect of cold work is predominant. Precipitation is retarded by heating at the alpha single phase region or remelting.
