The research works which are regarding with rapid solidification of some intermetalic compounds can be summarized as follows ;(1) From the observations for microstructures of rapidly solidified TiAl alloys, informations for phase boundaries among alpha titanium, Ti_3Al and TiAl in the titanium-aluminum binary equilibrium phase diagram which have not been established were estimated.(2) From the results of systematic investigation for the effect of ternary elements on the tendency of metastable phases appearance in rapidly solidified Ni_3Al alloys, it was revealed that additional elements which inhibit the appearance of meta-stable phases have effects of improving the plasticity of Ni_3Al alloys.Although it was not apparent the relationships between these two phenomena, this results would give an effective way of improvement for the lack of plasticity that is considered as a neck for application of interm etallic compounds to structural materials.

关于某些金属间化合物的快速巩固的研究作品可以总结如下；（1）（1）从对快速固化的TIAL合金的微观结构的观察结果，α-钛，Ti_3al和TiAL之间的相界界的信息，在钛 - 钛二元期间的效应中的作用并未估计的（从未估计的）。三元元素关于在快速固化的Ni_3Al合金中的可稳定阶段外观趋势的趋势中，据表明，抑制元稳定阶段出现的其他元素具有改善Ni_3Al合金的可塑性具有影响的影响结构材料的化合物。
