Thermocycling treatment of titanium alloys based on polymorphic transformation

The structure and properties of welds of titanium alloys VT6ch and VT22 after thermocycling performed in various modes are studied. The structure of the welds is studied by the methods of metallographic and x-ray diffraction analysis. The mechanical characteristics of the welds are determined by testing them for tensile strength, impact toughness, and crack resistance.
