The deformation behavior and deformation mechanism of GH3536 superalloy during cold deformation were meticulously investigated with diverse characterized means and testing methods are described.Moreover,the regulating effect of stacking fault energy on deformation mechanism and the orientation dependence of deformation twinning are revealed by means of simulated calculation.It is found through the tests that GH3536 alloy has extraordinary cryogenic properties,similar to the recently developed face-centered cubic high-entropy alloys.The strength and plasticity of the alloy increased simultaneously during loading at cryogenic temperature,which indicates an improved processibility.
