(c-bco) phase, in order to cope with the order-disorder transitions. A set of self-consistent thermodynamic parameters has been obtained to ensure the thermodynamic calculations well consistent with the reported experimental data, ...
至于形成哪种相则基本可以由相图得到 phasediagram 能否贴几张图来看看 phasediagram 能否贴几张图来让我看看 最好给出合金成分 如果你想确定是什么相 自然是用电子探针 加xrd衍射 phasediagram 你这问题就问得不专业 你成分也没给 图也没给 谁能知道 那些回复也都是大神猜...
