Abstract Scope |
Hot Isostatic Pressing (HIP) is used to improve the mechanical properties of metal specimens by increasing pressure and temperature inside a vessel. In this environment of high pressure and heat, plastic deformation and diffusion bonding are induced, internal pores within the solid body of specimen collapse, density increases, micro defects heal, and the mechanical properties are improved. The application of titanium alloys will grow in various industries particularly aerospace and biomedical due to their exceptional strength-to-weight ratio, corrosion resistance, and operating temperatures. The Ti-6Al-4V (Ti64) pieces were made from Arcam’s Q20 and A2X systems; both samples of HIPed and as-built EBM Ti64 will be cut into cross sections to check porosity, cracking, analyze density, as well as look at the microstructure. Hardness measuring, chemical analysis, tensile testing, and failure analysis will be done to compare HIPed and as-built pieces. |
