Abstract��The results shown that,under condition of higher cold rolling reduction,the yield strength and tensile strength decreased,the r��value and elongation decreased first,and then increased,meanwhile,BH��value is prone to increase gradually,with 36 MPa at maximum.With 70% cold rolling reduction,the maximun of yield strength and tensile strength was 270 MPa and 395 MPa respectively,and that of r��value and elongation was 1.7 and 39% respectively,while n��value had little change,It is concluded that larger grains and better synthetic properties were obtained under 80% cold��rolling reduction.
