摘      要：AZ31 wrought magnesium alloys are light weight materials which play an important role in order to reduces the environmental burdens in modern society because of its high strength to weight ratio,corrosion resistance,and stiffness and *** of this material are mainly in structural component i.e.,in constructions,automobile,aerospace,electronics and marine *** the present work,the microstructure characterization of the AZ31 alloys up to four ECAP passes at temperature of 573 K was observed for route *** grain size of the material was reduced from 31.8μm to 8μm after four ECAP *** properties of the alloy improved with increase in number of ECAP ***,X-ray diffraction analysis was carried out for as received and ECAP processed material.
