Raising the Fatigue Resistance of Titanium Alloys by High-Speed Deformation in the Range of Polymorphic Transformations

详细

Methods for raising the fatigue limit of critical parts by forming the required properties and structure in preforms from α + β titanium alloys by high-speed pressing at a temperature above the point of polymorphic transformations and subsequent heat treatment are described. Amethod for experimental determination of expedient thermomechanical regimes for raising the fatigue limit of the materials of articles is considered for billets from alloy VT9.
