3. Post-processing of additively manufactured Ti-6Al-4V parts
Post-treatments are designed to improve the mechanical properties of the parts, firstly by eliminating defects inherent to the process (porosity, roughness, residual stresses) and secondly by modifying the microstructure.

Hot isostatic pressing
Removal of internal porosity is typically achieved using Hot Isostatic Pressing (HIP)
. This treatment involves applying a pressure of 1,000 bar (100 MPa) for 2 h at a temperature of 920°C, followed by slow cooling. HIP treatment is extremely effective in eliminating porosities inside...[M 3 310]
