The results showed the specimens by vacuum sintering had a typical Widmannstatten microstructure, which possessed coarser prior β-grains and secondary platelet α+β-phase, but the alloy had a more microporosity and a lower tensile strength and ductility. After HIP treatment, prior β-grains and secondary platelet α+β-phase became fine and uniform, and the alloy possessed a less microporosity and a higher tensile strength and ductility.

结果表明：真空烧结Ti-6Al-4V合金具有典型的魏氏体组织，其初始的β晶粒粗大，β晶粒内为次生片状α和薄β相片，空隙较多，合金的强度和塑性较低；合金经热等静压处理后，组织明显细化且均匀，空隙很少或几乎没有，从而强度和塑性都有所提高。
