Notes:
Mechanical properties and elastic modulus were examined in order to clarify theinfluence on microstructures in Ti-26Nb-xSi, where x= 0.5, 1 in atomic percent, prepared by arcmelting, cold rolling and recrystallization heat treatment. On the basis of microstructuralobservations and phase analyses, it is evidently revealed that the microstructure of as-quenchedsample appeared to mixture appearance consisting of mostly bcc-structured β phase and smallamount of orthorhombic-structured α″ phase. Elongated structure parallel to the rolling directionwas observed in cold rolled samples, and equiaxed structure with the average grain size of about20μm was developed for the sample after recrystallization heat treatment. Randomly distributedfeature of pole figure was characterized without showing a specific texture component in asquenchedsample. Rotated cube, α-fiber and γ-fiber texture components were detected in cold-rolledsample. After recrystallization heat treatment the intensity of α-fiber texture component wasmarkedly decreased, while the rotated cube component becomes sharpened and γ-fiber componentremains relatively unchanged. From both elastic modulus and strength point of viewrecrystallization treatment would be desirable to meet the required mechanical properties of thepresent alloys for biomedical applications
