伸长率较AZ61镁合金提高了17.8%。

Abstract

Effects of yttrium on the ignition-proof

microstructure and mechanical properties of AZ61 magnesium alloy were investigated. The results indicate that proper Y addition can increase the ignition point and improve the mechanical properties of the alloy as a result in improvement of the structure and refinement of the grain size. The ignition point of the alloy is increased from 556℃ to 595℃ with 1.5% yttrium addition

increased by 39℃

exhibiting the desirable ignition-proof role

while with 1% yttrium addition

the ignition point is increased from 556℃ to 592℃

increased by 36℃

showing acceptable ignition-proof effects

meanwhile

desirable grain refinement in the alloy can be observedv and tensile strength and elongation are increased by 13.5% and 17.8%

respectively

compared with that of AZ61 matrix alloy

exhibiting the optimal mechanical properties.
