本文总结和归纳了作者和他人的实验资料,提出在过渡金属二元合金中,低稳定性化合物增大其非晶态形成倾向。讨论了组元晶体结构、原子半径差、组元电子构型、电负性差等因素与低稳定性化合物之间的关系。并提出了液相淬火二元非晶态合金形成经验规律。据此规律作者已探索出Ti-Pd,La-Si,Zr-Ga,Hf-Pd等非晶态新合金系。
A proposal was made of the increasing tendency of amorphous formation of the binary transition metal alloys caused by the incongruent-and congruent-melting compounds of lower melting temperature on the basis of synthesis of the previous experimental data, including the author's. The effects of crystalline structure, atomic radius difference, electronic structure and electro-negativity difference of eIements were discussed. An empirical approach to the formation of binary amorphous alloys by liquid quenching was summarized. Thus, certain new alloy systems, e.g., Ti-Pd, La-Si, Zr-Ga, Hf-Pd, etc. may be developed.
