摘要
本文通过宏合金化和微合金化结合的方法,进一步改善了Ni_3Al的室温塑性,在本实验条件下,按最佳硼合金化配制的Ni_3Al合金的室温拉伸延伸率为14%,而复合合金化得到的Ni_3Al则为35%。同时,实验结果还表明,只有Al当量含量(Mn%+Al%)小于化学计量值时,才能发挥复合合金化的优势。
An improvement on the room temperature ductility of Ni_3Al was made by
combination of microalloying and macroalloying with Mn and B. The elongation of Ni_3Al,
after optimum alloying with B, is 14%, but that of complex alloyed one obtained up to 35%.
Furthermore, this superiority of complex alloying seems to be only revealed with equivalent
Al, i. e., %Mn+%Al, less than stoichoimetric content.
