Deformation Degree Influence Titanium Zirconium Molybdenum Alloy’s Organization Structure

By observing different deformation degrees’ low magnification and high-powered microstructure photograph of titanium zirconium molybdenum (TZM) alloys was found, low-temperature sintering alloy billet has grain fine and uniform structure. After rolling, with deformation degree increases, the original equiaxed grain components along the deformation direction extending and carbide phase dispersed evenly, so the dispersion strengthening effect is more pronounced. When the deformation degree increases, the organization structure of grains becomes blurred, but the grain size and form are consistency good, a fiber distribution. And Mo grains coexist with each other so the intergranular binding force strong and TZM alloy susceptibility to crack greatly reduced. Meanwhile, the alloy grain boundary inside impurity segregation decreased, tensile strength and toughness has been greatly improved. As the deformation increases, the overall variation of the alloy structure is as follows: a large amount of deformation of TZM alloys occur carbide phase dispersed uniformly, high dispersion, fibrous tissue increased and more refined, the final alloy room temperature mechanical properties significantly improved.
