Abstract

The article presents the results of the structure study, as well as physical and mechanical properties of forgings made of titanium (α + β) alloy VT23M after heat treatment. The choice of the heat treatment type (double annealing) is has been reasoned. The influence of process parameters on the microstructure features and the level of strength and ductile characteristics, impact toughness, are studied. Based on the analysis, the temperatures of the first and the second stages of double annealing of forgings made of VT23M alloy are selected, providing the balanced set of mechanical properties and the favorable microstructure.
