Influence of processing technology on fracture feature of Ti6Al4V

Original language description

Selective laser melting is an advanced manufacturing technology providing alternative method of producing complex components directly from 3D computer models. The paper is focused on problems related with selective laser melting technology (SLM) used for preparing titanium based implants. Two series of ten Ti6Al4V samples were mechanically tested in tension and compression respectively before and after heat treatment. Annealing under argon atmosphere consisted of solution treatment at 955 oC followed by furnace cooling to 855 oC with water quenching and ageing at 600 oC with air cooling. Fractography study of fracture surfaces was performed using scanning electron microscopy and the observation was correlated with structural and mechanical properties of the SLM specimens in the condition as-built or heat treated. The failure features of as-built specimens corresponded to the microstructure with relatively high porosity, martensite needles, microcracks and residual stresses. The heat treatment resulted in the transformation of martensite to (alpha + beta) lamellar structure modifying plastic properties that corresponded to the morphology of fracture surfaces. In spite of the porosity occurrence both specimen series exhibited high mechanical properties in tension as well as in compression. (C) Published under licence by IOP Publishing Ltd.
