In this paper the macro-, microstructure, the hardness and the modulus of elasticity for the billet of the PT-1M alloy after expanding was studied. It was shown the expanding resulted to grain refinement near inner surface of the billet due to the recrystallization. The relationship between the structure through sections, the hardness and the modulus of elasticity was established.

Keywords: titanium alloy PT-1M, expanding, macrostructure, microstructure, hardness, modulus of elasticity
