Optimization of the technology for producing titanium products

The work optimized the technological parameters (pressing pressure and powder size) in the manufacture of titanium products by powder metallurgy methods. We established the influence of pressing pressure and powder fraction on the size and number of pores in the experimental samples, as well as on the mechanical properties of researched samples. We defined the optimal ratio of pressing pressure and powder size on the formation of the structure and properties of sintered titanium. According to the developed technology, the obtained indicators are close to the mechanical properties of industrial titanium Grade 2 (σ_R ≥ 345 MPa and hardness HB > 130). We obtained the dependency of the influence of technological parameters of titanium’s powder metallurgy on its properties. We determined the sensitivity of volumetric porosity, pore size, hardness, tensile strength and relative elongation to pressing pressure and powder size. We proposed the optimal pressing pressure and powder size, which provide high indicators of hardness and tensile strength of sintered titanium.
