Abstract: The hot deformation behavior of low nickle electric heating alloy was studied by means of hot simulating technology.True stress-true strain curves and hot deformation microstructures were given. The dynamic recovery was the main type of softening in hot deformation,and a large number of twin crystals were generated during holding time after hot deformation.In addition,the influencing factors of this alloy on hot deformation behavior were analysed.The additive element of aluminum had little influence on the high temperature strength,but restrained the generation of dynamic recrystal and twin grains.Furthermore,the activated energy of hot deformation for recovery were provided.
