Influence of grain size on microstructure and porosity of biocompatible Ti-35,5Nb-5,7Ta alloy processed via powder metallurgy

Popis výsledku v původním jazyce

Beta-titanium alloys containing only fully biocompatible elements are very perspective materials for production of bioimplants. They have good properties for use as biomaterials, including above mentioned biochemical compatibility, low elastic modulus (important for biomechanical compatibility), in comparisson with previously used alloys. Moreover they are suitable for forging. Perspective method with respect to final price is powder metallurgy. There are several advantages in compare with usual methodslike arc melting. On the other hand the problem of powder metallurgy could be the porosity of the final product after sintering. In this paper, the influence of the grain size and parameters of sintering used during the preparation of biocompatible Ti-35,5Nb-5,7Ta alloy on its microstructure and compactness, which influence properties of the alloy, were studied. Measurements of porosity depending on sintering time at 1400 degrees C were made. Furthermore the microstructure of specimens
