Tin (Continued from page 64) increased the elongation; and as the temperature increases, the elongation first increases and then decreases at 350 ℃, homogenization of the material after 20% elongation. Results from the above analysis shows that: choose the right within a certain range of extrusion ratio and extrusion temperature can effectively provide AZ3l magnesium alloy tensile strength and elongation. Thereby improving the tensile properties. 3 Conclusions (1) cast and homogenized alloy extrusion processing AZ3l organizations have taken place after the dynamic recrystallization, grain was refined. Comparison with the cast, uniform treatment can effectively increase the mechanical properties of magnesium alloy AZ31B, after homogenization of the product after the extrusion rate of 20% elongation. (2) With the compression ratio increases,ugg prezzo, the grain was refined. Magnesium alloy tensile strength and elongation are improved. (3) AZ31 magnesium alloy after extrusion of the organization by the extrusion temperature, with the extrusion temperature increases, the tensile strength and elongation of the corresponding changes, the more favorable at 350 ℃.
