Mechanical Property Evaluation of Ti-6Al-4V Parts Made Using Electron Beam Melting

Abstract

Cylindrical Ti-6Al-4V parts were built in vertical and horizontal orientations using electron beam melting. Tensile tests and fatigue tests were carried out. The specimens were tested in as-built and machined conditions to understand the effect of surface finish on mechanical properties. The fracture surfaces were analyzed using scanning electron microscopy and the fractography results were correlated with the mechanical properties. Based on the results the effects of part orientation and surface finish on mechanical properties are discussed.
