Abstract

The study of influence of alloying elements content (aluminum, tin, silicon and iron) in the near alpha titanium alloy VТ46 in room and elevated temperatures (500 and 550°С) is performed. It is found that reducing the content of elements such as aluminum, tin, silicon comparing with a nominal composition leads to decrease in creep strength characteristics of the material. Content of iron has a significant effect only on the level of strength in relatively low test temperatures.
