The influence thermoplastic processing of the titanium Grade 2 on the nanoindenation properties
Języki publikacji
Abstrakty
Czysty tytan jest materiałem pożądanym w biotechnologii ze względu na doskonalą biozgodność oraz brak toksycznych pierwiastków, takich jak wanad czy aluminium. Niestety w stosunku do powszechnie używanego stopu na protezy Ti6Al4V jest on materiałem o niskich właściwościach mechanicznych. Obróbka termoplastyczna tytanu miała na celu poprawę jego właściwości mechanicznych poprzez zredukowanie wielkości ziarna. Wykonano eksperyment polegający na ściskaniu próbek tytanu w podwyższonej temperaturze i przy różnych prędkościach odkształceń. Uzyskano krzywą naprężenie-odkształcenie oraz obrazy mikrostruktury tytanu, które wskazywały na redukcję ziarna. Następnie wykonano pomiary nanoindentacyjne twardości oraz modułu Younga. Wyniki wskazują na nieznaczny wzrost twardości i sztywności w większości przypadków. Dla wysokich prędkości odkształcenia zaobserwowano spadek tych wartości.
Pure titanium is a desired material in biotechnology due to its excellent biocompatibility and the absence of toxic elements like vandium or aluminium. Unfortunately, in comparison to widely used Ti6Al4V alloy it has low strenght properties. Therefore, thermoplastic processing was used as means to improve its mechanical properties by the grain size reduction. An experiment of samples compression in raised temperature and various strain rates was conducted. The stress-strain curves and microstructure observations were made. Both indicated grain reduction. In the next step nanoindentation hardness and Young modulus measurements were made. The results indicate slight increase in hardness and stiffness in most cases. For the high strain rates a decrease in those values was observed.
