Elastic modulus of phases in Ti-Mo alloys
چکیده انگلیسی
In this work, a series of binary Ti-Mo alloys with the Mo contents ranging from 3.2 to 12 at.% were prepared using non-consumable arc melting. The microstructures were investigated by X-ray diffraction and transmission electron microscope, and the elastic modulus was evaluated by nanoindentation testing technique. The evolution of the volume fractions of ω phase was investigated using X-ray photoelectron spectroscopy. The results indicated that the phase constitution and elastic modulus of the Ti-Mo alloys are sensitive to the Mo content. Ti-3.2Mo and Ti-8Mo alloys containing only α and β phases, respectively, have a low elastic modulus. In contrast, Ti-4.5Mo, Ti-6Mo, Ti-7Mo alloys, with different contents of ω phase, have a high elastic modulus. A simple micromechanical model was used to calculate the elastic modulus of ω phase (Eω), which was determined to be 174.354 GPa.
