| ABSTRACT |
| The aim of the present paper is to investigate the hardness and elastic modulus of Ti6Al4V alloy produced by CAD/CAM milling and selective laser melting. The Vickers micro-hardness is measured, while the modulus of elasticity is determined by new developed methodology consisting of bending test and finite element analysis. It was established that the manufacturing method lead to differences in the micro-hardness and elastic modulus of the milled and SLM samples. The measured micro-hardness of the Ti6Al4V alloy was higher for the SLM samples (396 HV) compared to the milled ones (347 HV). The values of the modulus of elasticity of Ti6Al4V alloy are 180 GPa for the milled and 120 GPa for the SLM fabricated samples. They are higher than the data given in the literature or by the manufacturers. Subsequent heat treatment with porcelain firing modes slightly decreased the micro-hardness to 322 HV for the milled and 388 HV for the SLM produced samples and had almost no effect on the modulus of elasticity for both groups. |
