Abstract

The structure and mechanical properties of forgings from heat-resistant near-α-titanium alloy VТ41 with different iron content are examined in this paper. It has been established that the increase in the iron content leads to the increase in strength proper-ties of the material in the working temperature range and some decrease in characteris-tics of ductility and toughness. Increasing the iron content is accompanied with increased sensitivity to stress concentrators under different types of tests.
