Microstructure and Mechanical Properties of Titanium Alloy VT6 and VT20L Diffusion Joints

  • Published:
Metallurgist Aims and scope

Joints of VT6 and VT20L titanium alloys are prepared by diffusion welding in an autoclave (at a temperature of 920°C, a pressure of 4 MPa, and holding time of 4 h) and during hot isostatic pressing (at a temperature of 930°C, a pressure of 100 MPa, a holding time of 2 h). Alloy Ti6Al4V components are prepared in two different ways, i.e., by rolling and selective laser melting methods. After welding in an autoclave, defects are found in the microstructure of the specimens in the diffusion joint area. No defects are found within the microstructure of the specimen prepared by hot isostatic pressing. Welded specimens have a high level of strength properties corresponding to the VT20L base alloy material level.
