摘要：

Laser powder bed fusion (LPBF) technology offers a promising solution to the fabricability challenges of titanium alloys; however, it introduces defects such as porosity and cracking. Here, we evaluated the effectiveness of hot isostatic pressing (HIP) in eliminating defects and enhancing the overall properties of LPBF Ti-6Al-4V alloy. Our findings indicated that LPBF Ti-6Al-4V alloy after HIP established better corrosion resistance and ductility. These improvements could be related to the decomposition of alpha' phase and the elimination of internal defects within alloy matrix. Furthermore, the application prospect of LPBF Ti-6Al-4V alloy in spent fuel reprocessing environment was expounded.
