Effect of Hot Isostatic Pressing on the Structure and Properties of Articles from Alloy VT6 Obtained by Cold Gas-Dynamic Spraying

  • Published:
Metal Science and Heat Treatment Aims and scope

Samples of titanium alloy VT6 obtained by the method of cold gas dynamic spraying (CGDS) and subjected to hot isostatic pressing (HIP) for lowering the porosity and improving the mechanical properties are studied. The HIP is conducted at a temperature of 900°C and a pressure of 110 MPa. This reduces the volume fraction of pores from 8 to 0.5% and raises the ultimate strength of the samples from 70 to 950 MPa and the elongation by 12%.
