Abstract

The paper describes the studies focused on structure and mechanical properties of bars made from heat-resistant near-α-titanium alloy VТ41 with different iron contents. It was established that an increase in Fe content leads to modification of microstructure, an increase in strength and fatigue characteristics of the material and to a decrease in ductility characteristics, fracture toughness and heat resistance. In addition, rising of Fe content is accompanied by an increase of sensitivity to stress concentrators at different types of tests.
