摘要
采用快速凝固技术在ＡＬ－３．１８Ｔｉ－０．６５Ｃ合金（Ｗｔ％）合金中获得了是弥散分布的ＴｉＣ相颗粒．结合常规和快速凝固组织的分析对比，研究和探讨了相的形成过程和机制；快凝技术为研制ＡＬ／ＴｉＣ自生复合材料开辟了新的途径．
The microstructures of AL-3.18Ti-0.65C alloy DC-casting and melt-spun have been char actetized using TEM,EELS and X-ray diffraction.In the melt-spun,uniform and fine-scale dispersions of intermetallic phase are single TiC.phase.The formation mechanism of TiC phase is discussed.
