Purpose: The major problem restricting universal employment of intermetallic phase base alloy is their low
plasticity which leads to hampering their development as construction materials. The followi...
Water vapor effect on high-temperature oxidation behavior of Fe3Al intermetallics

Fe3Al intermetallics (Fe3Al, Fe3Al-Zr, Fe3Al-Zr,Mo and Fe3Al-Zr,Mo,Nb) were oxidized at 950 °C in dry and humid (11 vol% water) synthetic air. Thermogravimetric measurements showed that the oxidation ...
利用Ｍｏｎｔｅ Ｃａｒｌｏ方法分析了Ｃｏ，Ｃｒ和Ｖ三种代位合金元素在Ｆｅ３Ａｌ金属间化合物中亚点阵上的占位性质.分析表明：Ｃｏ占据Ａｌ的最近邻位置.Ｃｒ和Ｖ主要占据Ａｌ的次近邻位置，并有少量的Ｃｒ和Ｖ占据Ａｌ的位置，三种代位合金元素中，Ｖ原子明显降低了合金的Ｄ０３有序度.
B2结构Fe3Al单晶在室温拉伸过程中的取向转动
Fe3Al 单晶 转动 B2结构

借助于ＥＢＳＤ方法, 研究了８个位向Ｂ２结构Ｆｅ３Ａｌ单晶室温拉伸变形时晶体取向的转动. 结果表明, 无论原始取向如何, 在拉伸过程中晶体拉伸轴总会向着〈１１０〉方向转动, 也即〈１１０〉为稳定取向. 当晶体拉伸轴转向取向三角形中部的软取向时, 晶体表现为几何软化, 相应的加工硬化率较低. 反之, 当晶体拉伸轴转向〈００１〉－〈１０１〉对称线时, 晶体表现为几何硬化, 相应的加工硬化率较高.
