对两种ＴｉＡｌ３形态的ＡｌＴｉＢ中间合金的重熔试验表明：ＴｉＡｌ３晶体形态在１０００℃以下有明显遗传性；过热至１１００℃时ＴｉＡｌ３晶体形态发生变异，原先为块状的ＴｉＡｌ３晶体转变为针片状，原先为针片状的ＴｉＡｌ３晶体则变厚变短，有转化为块状的倾向。
The remelting tests on two TiAl3 master alloys show that the crystal morphology of TiAl3 is obviously hereditary under 1000 ℃. When the temperature is over 1100 ℃, the crystal morphology of TiAl3 is changed. The bulk of TiAl3 crystal is changed into needle-like , The original needle-shaped TiAl3 crystal becomes thicker and shorter, tend to be transformed into massive.
