1)  α-Mg dendrite
α-Mg树枝晶
2)  α(Al) dendrite
α(Al)树枝晶
3)  primary phaseα-Mg
α-Mg初晶
1.
The results show that,with Al content increasing,primary phaseα-Mg in as-cast Mg-Al binary alloy decreases,while eutectic microstructure severely increases.
结果表明:铸态Mg-Al二元合金在含Al(10%~25%,质量分数,下同)范围内,随Al含量增加,α-Mg初晶体积分数逐渐减少,形态由不规则的团絮状变为蔷薇花状,直至小块状;共晶组织体积分数剧增,硬脆相β-Mg17Al12呈网状连续分布,α和β两相以共生生长方式成为片层状共晶组织;ECAP能明显破坏硬脆相β-Mg17Al12网状连续分布,细化共晶组织和初晶α,并能使初晶α中析出弥散细小的β,起到弥散强化作用,使不同Al含量的Mg-Al二元合金不仅抗拉强度得到显著提高,而且塑性获得极大改善,尤其是Mg-15Al合金,ECAP后抗拉强度σb从150MPa提高到269。
