用电子背散射衍射（EBSD）研究了Al含量为1.48at%的TiAl合金在适当热处理后发生的块状γ相变。证明了γ m核与相邻α 2晶粒之间的特殊晶体学关系。同时，对相邻γ m畴间的关系也进行了表征。这些结果证实了以前关于大质量γ转变机制的假设。
The massive γ transformation which occurs after adequate thermal treatment in TiAl alloys with ∼48 at % Al has been investigated by EBSD analysis. A particular crystallographic relation between the γmnucleus and the adjacent α2grain has been demonstrated. The relations between adjacent γmdomains have also been characterized. These results confirm previous assumptions about the mechanism of the massive γ transformation.
