Ti-43Al-9V铸造受阻收缩及气孔缺陷

Research on the Casting Shrinks Properties and Air Hole of Ti-43Al-9V Intermetallic Compounds

考察了Ti-43Al-9V钛铝金属间化合物的受阻收缩,评价了Ti-43Al-9V在离心浇注条件下的气孔缺陷。Ti-43Al-9V的受阻收缩率较大。在离心浇注条件下,Ti-43Al-9V棒形件出现了以卷入性气孔为主,同时伴有反应气孔的气孔缺陷。

In this paper, the degree to Ti -43Al -9V casting shrinks have been measured. Casting defects of Ti -43Al -9V used the centrifugal casting is also researched. Ti -43Al -9V has great casting shrinks in the process of cooling but the ability of compensating shrinks is bad. The immixture air hole is the main air defects of casting.
