Mechanical properties characterization of Ti6Al4V for artificial hip joint materials prepared by investment casting

Abstract The Investment Casting (IC) process is a type of casting that can produce the suitable shape and size components by minimizing porosity defects. However, research on ICs for manufacture artificial hip joints made from Ti6Al4V still lacking. Therefore, purpose this study to determine mechanical properties an joint casted using investment method. stages used in are wax injection, ejection pattern, tree assembly, slurry coating, final sand mould, dewaxing, preheating, pouring, product. characterization IC products was carried out tensile test, hardness impact test. yield strength, Ultimate Tensile Strength, Elongation (%), Hardness (HRC) Impact Strength obtained were 636 MPa, 687 17%, 29 HRC, 5.3 J, respectively. lower oxygen content Ti Alloy after resulted decrease ultimate hardness, energy. low increased ductility (% elongation).
