AREA: Engenharia de Materiais e Metalúrgica
SUMMARY:

Two Ti-Si-B alloys (namely: Ti-2Si-1B, Ti-6Si-3B) were produced by HIGH ENERGY MILLING (MAE). The MAE was carried out with a rotation of 200rpm, in a proportion of 1:20 mass/ball, observing times of 4h and 8h, for homogenization. The best sintering temperature was evaluated, namely: 1250°C, for a treatment time of 4h. In this way, the material was characterized in terms of phase variations and porosity to establish the best parameters for both alloys. Granulometry, SEM, DTA/TG, XRD, MO, density analyses, in addition to microhardness, wettability and cell growth tests were also carried out to better characterize the material obtained.
