| 摘 要： | 通过对比试验发现：不同组织的Ａｌ－５Ｔｉ－１Ｂ中间合金具有不同的细化效果。借助金相，ＳＥＭ和ＴＥＭ等手段对组织进行了分析对比，探讨组织遗传对细化效果的影响。实验结果表明：利用快速凝固法制备的该中间合金，其块状ＴｉＡｌ３化合物细小，ＴｉＢ２等微小粒子分布弥散，具有最佳的细化效果。

| Abstract: | It has been found by comparative experiments that Al-5Ti-1B master alloys with different structures have different grain refinement efficiency. The microstructure of the master alloys have been characterized using metallograph, SEM and TEM. The effect of structural heredity on grain refinement efficiency is discussed. The experimental results show that the AlTiB master alloy manufactured by rapid solidification method comprises fine TiAl_3 phases and seperate array of boride microparticles, and has the best grain refinement efficiency. |
