DO_3有序铁铝合金加锰后有序化温度的研究

Research on Ordering Temperature in DO_3 Fe-Al Alloy after Mn Addition

通过电阻法、X射线衍射法分析研究 Fe- 2 8Al合金和 Fe- 2 8Al- 1.5 Mn合金在连续加热过程中的有序转变 ,并就合金元素 Mn和原始组织对合金有序化转变的影响进行了探讨。研究结果表明 ,微量合金元素 Mn加入 Fe- 2 8Al合金后可提高合金的 DO3与 B2 型有序转变温度、延缓

The ordering of Fe 28Al and Fe 28Al 1.5Mn alloys is studied during heating,with electron resistance method and X ray diffraction method.The results show that addition Mn into Fe 28Al alloy can raise the translation temperature of DO 3 to B 2 ordering type,and prolong the formation of DO 3 structure.
