-silicon-copper alloys are enhanced through precipitation hardening. The response of these alloys to age-hardening is very slow. To overcome this problem, 0.2, 0.4 and 0.7 wt.% magnesium were added to Al-10.5Si-3.4Cu alloy. The new alloys were subjected to two types of precipitation hardening processes different in the solutionizing stage. The results showed that the presence of various amounts......
Secondary hardening behavior of 15CrMnMoV thin rolled tubeCi DING and Weixin HAN Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China摘 要:15CrMnMoV rolled tube is applied to many critical parts of helicopter. The secondary hardening behavior of the steel which varied with the treating process is essential for further usage......
and large forging is caused by the secondary phase precipitation from the transformed β above 830 ℃. The precipitation strengthening effect on the little bar is smaller than that of the large forging because of the recrystallization softening effect.
