Effect of environmental temperature on damping capacity of Cu-Al-Mn alloy JIAO Yu-qin(焦玉琴)1, 2, WEN Yu-hua(文玉华) 1, LI Ning(李 宁)1, HE Jia-qiang(何加强)1, TENG Jin(滕 劲)1 1. School of Manufacturing...; Abstract: The effect of environmental temperature on the damping capacity of Cu-7.66Al-9.52Mn (mass fraction, %) alloy was studied. The result shows that with increasing the environmental......
for basal slip in Mg alloys deformed at room temperature or high a little, and others depend on twinning[14-15]. Generally, the yield strength for tension is asymmetric to that for compression in the case...
