Effects of Remelting on Microstructure and Properties of Ti-1Al-8V-5Fe Alloy Prepared by Selective Laser Melting AITranslate
Abstract AITranslate
To eliminate theβspots in Ti-1 Al-8 V-5 Fe(Ti185)alloy produced by conventional casting process,the large-particle-size Ti185 alloy powder was formed by selective laser melting,and the selective laser melting Ti185 alloy was optimized by remelting process.The microstructure and mechanical properties of the top,middle and bottom positions of the formed sample before and after remelting were analyzed.The results show that macroscopic cracks exist in the Ti185 sample formed by selective laser melting,and the remelting process can effectively suppress the initiation of the cracks.The microstructures of the formed samples by selective laser melting and remelting optimization are all composed of equiaxedβphase,and subcrystalline microstructure exists inside the equiaxed grains.The maximum compressive strength of the formed sample by selective laser melting which is optimized by remelting is 2127±120 MPa,and its fracture strain is 21%±5%,which shows a decrease in compression performance compared with the sample before remelting.
