The thermo-plastic and thermo-deformation characteristics of S31042 alloy were studied by using Gleeble-3800 thermal simulation test machine, and the hot processing maps were established. The results show that in the deformation range of 900-1250 ℃, the alloy has good thermoplastic;the hot deformation activation energy is 467. 412 kJ/mol;the suitable processing initial deformation temperature range is between 1200-1250 ℃ through processing map analysis, and the microstructure of forging billet is fine and uniform by using this parameters.
