连续碳化硅纤维增强Ti－15－3合金基复合材料界面的初步研究

An Experimental Investigation of Interface in Continuous silicon Carbide Fibre-Reinforced Ti-15-3 Alloy Matrix Composite

本文对连续ＳｉＣ纤维增强Ｔｉ－１５－３合金基复合材料的界面进行了初步的研究。试验结果表明，真空热压或热等静压复合固结ＳｉＣ／Ｔｉ－１５－３试样中界面反应区尺寸约为４μｍ左右，界面部位含有较多的Ｔｉ、Ｓｉ和较少的Ｖ、Ｃｒ、Ｓｎ、Ａｌ。

n this paper,the fibre/matrix reaction zone in comtinuous SiC fibre-reinforced Ti-15-3 alloy matrix composite has been inititally investigated The experimental results indicate that the thickness of the reaction zone in the SiC/Ti- 15-3 sample fabricated by vacuum hot pressing or hot isostatic pressing is approximate-ly 4μm, the concentration of Ti,Si is high and the concentration of V,Cr,Sn and Al is low within the reaction zone .
