| 摘 要： | 研究了钛硅系铸造合金的相组成、微观组织。X射线衍射试验表明，随着硅含量的增加，Ti5Si3相（ζ）的衍射峰越来越明显。同时，合金由固溶体的片状或网蓝片组织逐渐演变为典型的棒状共晶组织。结果表明，钛硅系铸造合金与传统的铸造钛合金有着截然不同的微观组织特征。

| Abstract: | The phase constituent and microstructure of Ti-Si syst em cast alloy wer e studied. It was found by XRD that the peak values of the Ti5Si3 phase were out standing gradually with the increase of the Si content in the alloy. And th e microstructure of the Ti-Si alloy evolved from the lamellar or basket we ave solid solution structure to the typical rod eutectic structure. The results showed that the microstructure of the cast Ti-Si alloys were completely differ ent from the microstructure of the troditional cast Ti alloy. |
