A CrMo alloy steel with similar composition to FeCrMoPC block amorphous alloy is numerically simulated by using Deform-3D software in the subcooled liquid phase of FeCrMoPC block amorphous alloy with equal diameter Angle extrusion.The equivalent stress,equivalent strain,extrusion load and temperature field of the material are analyzed through post-processing.A theoretical optimum temperature window for ECAP deformation of Fe-based amorphous alloys is found to be 465℃.
