Abstract
Ti6Al4V is a lightweight alloy often used in applications prone to impact. In the present contribution, the influence of strain rate on the fracture properties of Ti6Al4V is studied. Tensile, shear and plain strain tests are carried out on sheet material, tensile and torsion tests on bulk Ti6Al4V at static and dynamic strain rates. Fracture strains, fracture morphology, void densities and void distributions close to the fracture surface are studied using high speed imaging combined with DIC and SEM micrographs. Results show that stress triaxiality has a major influence on the fracture strain, whereas strain rate only affects the fracture strain in shear. The fracture strain of tensile tests on the bulk material is larger than the strain in the sheet material. In all experiments a ductile fracture is obtained; larger dimples are found in the shear samples compared to the tensile and plane strain samples.
