主　　题：corrosion-resistant alloy G3 825 stress-strain curve hot plasticity 

摘      要：The G3 and 825 alloys,with excellent combination of mechanical properties and corrosion resistance,can be used in hot,and acid *** simulation tests were conducted on the alloys G3 and 825 in the THERMECMASTOR-Z simulator,at temperature between 1030 and 1300 ℃,with strain rate from 1 to 50 s-1 and strain ε=*** variations of flow stress with deformation temperature and strain rate were *** of alloy structure with hot deformation and effect of strain rate on alloy dynamic recrystallization have been studied through microstructure observation by OM,SEM and ***,hot plasticity characteristics of alloy were analyzed by temperature-reduction of area *** results showed that available hot working temperature for G3,G3-Z and 825 was 1100 to 1240 ℃,1130 to 1220 ℃ and 1050 to 1240 ℃,*** reliable information on hot working in the alloy pilot production in steelwork is given.
