【摘要】 研究 3 0 %～ 5 0 %含铝量的高铝锌基合金的组织和性能以及温度对力学性能的影响。从差示扫描量热分析和显微组织得出 :随含铝量的增加 ,合金的熔点提高 ,α相枝晶增多 ,晶间的共晶体减少。表明含 5 0 %Al的ZA5 0合金具有较好的力学性能和高温性能。更多还原

【Abstract】 The mechanical properties and microstructures of 30%～50% Al-content Zn-based alloys were studied. According to the results of DSC and microstructure analysis, the more Al content, the higher melting point of the alloy, but the more α phase dendrites, the less eutectic cementite. The results showed that ZA50 containing 50% Al content is excellent in mechanical and high-temperature properties.更多还原
