چکیده انگلیسی
The present study is focused on mechanical properties that result from cold rolling and aging treatments applied to TiNbSn alloys comprising different Nb (35% and 42%) and Sn (0% and 2.5%) contents. The alloys were arc melted, homogenized, solubilized, cold rolled and aged at 400 °C for different aging times. A set of characterization tests performed, included microstructural analysis, X-ray diffraction, microhardness, tensile tests and fracture analysis. The alloys contained all three β, α” and Ï phases after cold rolling, regardless of the alloying content. The solid solution effect led to changes in the alloys' mechanical behavior. Furthermore, the alloys presented α phase precipitation, and it led to a peak-aged stage after different aging times due to the Nb content. The alloys containing 42% and 35% Nb content reached the peak-aged stage within 48 and 72 h, respectively. The α phase precipitation in the alloys at peak-aged stage increased the hardness, tensile strength and elastic modulus of the alloys; however, it also caused ductility to decrease. The fine dispersed precipitates of the α phase generated small and shallow dimples, which are a characteristic fracture micromechanism of peak-aged alloys.
