is directly related to the precipitation of particles enriched Cu, Ni and Mn. Key words: ZA27 alloy; Mn-Ni alloying; super plasticity; mechanical property Mn, Ni联合加入可显著提高铸态合金高温强度, 使瞬时抗拉强度提高46%. Mn, Ni联合加入提高高温强度的主要原因是合金的非平衡三相共晶中有大量较粗化的富镍相粒子(如图1(c)所示), 可有效提高高温强度低的非平衡三相共晶的高温形变抗力. 单独添加0.5%Mn, 在铸态ZA27合金的非平衡三相共晶中, 无富锰新相粒子生成[5, 6], 故不能有效强化高温强度......
