THE INFLUENCE OF ZR ON MICROSTRUCTURE OF BETA-TITANIUM ALLOYS
Popis výsledku v původním jazyce
Beta titanium alloys are nowadays very often used in bioapplications due to their properties (e. g. corrosion resistance, low Young's modulus and biocompatibility). Alloys with nominal chemical composition Ti-35Nb-XZr (X=0, 2, 4, 6 and 8 wt.%) were studied in this work. The influence of Zr on microstructure was the aim of this work. As-cast specimens were homogenized, hot forged and solution treated (850 degrees C/0.5h/water quenched). Light optical microscopy (OM) and scanning electron microscopy (SEM)with electron back scatter diffraction (EBSD) were used for microstructural characterization. The microstructure of hot forged alloys with low Zr fraction consists mainly of alpha" martensite. With increasing Zr content the microstructure changes into single beta-phase. Similar results were obtained for solution treated specimens. Zr influences also recrystallization process during hot forging and solution treatment and that results into different grain sizes depending on Zr fraction.
