摘要：

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 omega 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 alpha and beta phases, respectively, have a low elastic modulus. In contrast, Ti-4.5Mo, Ti-6Mo,Ti-7Mo alloys, with different contents of omega phase, have a high elastic modulus. A simple micromechanical model was used to calculate the elastic modulus of omega phase (E-omega), which was determined to be 174.354 GPa. (C) 2015 Elsevier Inc. All rights reserved.
