摘      要：Forward extrusion experiments of as-cast AZ31 magnesium alloy were conducted at different temperatures and different extrusion ratios using the as-cast billets with and without homogenizing *** mechanical properties of pre-and post-extrusion of the two kinds of billets were *** results show that the mechanical properties of post-extrusion of the two kinds of billets all are obviously improved compared with those of *** elongation of post-extrusion using the billet with homogenizing is higher than that without homogenizing,but the tensile strength is lower than that without *** the extrusion ratio increases,the elongation and tensile strength of post-extrusion of two kinds of billets all will increase *** the extrusion temperature of billet without homogenizing increases,the tensile strength of post-extrusion will decrease obviously and the elongation of post-extrusion will change to a small *** the billet with homogenizing,the tensile strength of post-extrusion will decrease in some sort when extrusion temperature increases.
