摘要：
Sr added ignition-proof AZ91D-0.3Be magnesium alloy was prepared. The influence of Sr content on microstructure and mechanical properties of the alloy was studied. Results show that the microstructure of ignition-proof AZ91D-0.3Be magnesium alloy is refined by a small amount of Sr addition. It is due to that the enrichment of a few Sr atoms in solid liquid interface in the process of magnesium alloy solidification inhibits grain growth and accelerates more nucleation. However, with increasing of Sr addition the microstructure is coarsened. By 0.01% Sr addition the tensile strength of as-cast experimental alloy is increased by about 25% and that of both the solid-solution and aged alloy is increased by about 40%. The elongation of as-cast alloy is increased by about 20% and that of solid-solution alloy increased by about 30%.
