Ti/Al(Ti-50at.%Al) composite powders were prepared by high-energy ball milling followed by reaction sintering heat treatment at 550C ~ 650C for 2 hours. Mechanical alloying of TiAl had been performed in a high energy plant ball after different milling times and pre-sintered at different temperatures. The particle sizes of Ti/Al powders were analyzed by scanning electron microscopy (SEM).

Authors Zhongwu Liu Kunpeng Su Yitian Cheng Raju V RamanujanAffiliation South China University of TechnologyThus they exhibited a significant reduction in size. The results indicate that the particle size of SiC and CuAl 2 was refined greatly after 6 h of high energy ball milling. However, it is clear that the particle size distribution even after the longest period of milling, 6 h, showed no significant narrowing.
