由于Mn—Al二元系在等原子成分处经特殊处理后存在着铁磁性合金,而Ga、Al在周期表中系同族元素,所以对Mn—Ga合金进行系统的探讨是十分必要的,本工作主要用Ⅹ—射线的方法,还配合了差热分析,对Mn—Ga二元系的相平衡关系进行了全面的研究。在整个系统内共配制了43个合金。几乎所有的合金都是脆性的,当合金在适当温度经15天的均匀化处理后,很容易碎成小于
Due to Mn-Al binary system after the special treatment at the same atomic composition of ferromagnetic alloys, and Ga, Al in the periodic table of the same family of elements, so the Mn-Ga alloy systemically discussed is very necessary, the Work mainly X-ray method, but also with the differential thermal analysis of the Mn-Ga binary system phase equilibrium relationship conducted a comprehensive study. A total of 43 alloys were prepared throughout the system. Almost all alloys are brittle, when the alloy at the appropriate temperature after 15 days of homogenization, it is easy to break into less than
