AN ATTEMPT TO IMPROVE AMBIENT DUCTILITY OF Ni_3Al BY COMPLEX ALLOYING WITH Mn AND B
Mn,B复合合金化对Ni3Al室温塑性的影响

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.
