In the research work, the influence of rolling conditions on the formation of rolled products from titanium powder and their influence on the density and mechanical properties of powder titanium rolled products were studied.
The influence of forming modes on the density and mechanical properties of powder titanium rolled products under rolling conditions at temperatures from 20 to 600 oC both in an argon atmosphere and in air was studied.
It was established that the use of the asymmetric rolling method allows to significantly improve the mechanical properties of powdered titanium strips compared to symmetric rolling due to the shear component of the deformation, which improves the conditions of contact formation at the particle boundaries. The quality of contacts between particles in materials obtained by asymmetric rolling is an order of magnitude higher than in materials after symmetric rolling.
The obtained results show directions for improving the rolling technology, which make it possible to obtain materials from titanium powder without sintering, the dynamic mechanical characteristics of which (elasticity and damping ability) are close to those of compact titanium
