Abstract

The invention discloses a preparation method of a high-ductility titanium alloy material for aviation, and relates to a method for manufacturing a titanium alloy plate. The preparation method aims tosolve the problem that an existing titanium alloy plate is low in strength, low in fracture elongation, low in fracture toughness, low in corrosion performance and low in electrical conductivity, so that the use requirements of the titanium alloy pre-stretched thick plate for aviation cannot be met. The preparation method comprises the following steps of 1, preparing a titanium alloy melt; 2, preparing a square ingot; 3, annealing; 4, preparing a titanium alloy square ingot; 5, preparing a plate blank; 6, heating; 7, preparing a titanium alloy plate; 8, cutting off; 9, carrying out solid solution treatment and quenching; 10, stretching and straightening; 11, carrying out aging treatment; 12, sawing to obtain the titanium alloy pre-stretched thick plate for aviation. According to the method, the titanium alloy pre-stretched thick plate for aviation can be obtained.
