Abstract
This invention relates to nonferrous thermomechanical treatment of titanium alloys and can be used for manufacture of structural parts and components of high-strength near-beta titanium alloys for the aerospace application, mainly landing gear and airframe application. Multiple heating operations above or below beta transus temperature (BTT), hot working with the specified strain and cooling makes near-net shape forgings with stable properties having sections with thickness 100 mm and over and length over 6 m with the guaranteed level of mechanical properties, including ultimate tensile strength over 1200 MPa with fracture toughness, K, not less than 35 MPa√m and fracture toughness, K, over 70 MPa√m with ultimate tensile strength not less than 1100 MPa.
