영문 초록

Recently, mechanical Alloying(M/A) process of Bi-In powder system which has negative mixed enthalpy and various intermetallic compounds was investigated. The solidification process on the uniform refinement of microstructure and the forming of non-equilibrium phase was examined by varying alloying time and composition materials. When the experiment wasdone in Bi-30at%In and Bi-50at%In, intermatellic compounds were formed at 2 minutesin the early stage of M/A, and most of them are known as BiIn, BiIn2 and Bi3In5. Experimental results indicate that the constant saturation values are obtained at the early stage of mechanical alloying process due to the refinement of grain size and work hardening.
