The Use of SPS for High-Rate Diffusion Welding of High-Strength Ultrafine-Grained α-Titanium Alloy Ti-5Al-2V

The article provides an example of applying the technology of spark plasma sintering (SPS) to ensure high-rate diffusion welding of high-strength ultrafine-grained (UFG) α-titanium alloys prepared by equal channel angular pressing. Weld seams produced from Ti-5Al-2V UFG α-titanium alloy and obtained through SPS are characterized by high density, hardness, and corrosion resistance.
