Short-process preparation method for medium-strength and high-toughness titanium alloy medium-thickness plate

The invention discloses a short-process preparation method for a medium-strength and high-toughness titanium alloy medium-thickness plate. The short-process preparation method comprises the following steps that 1, raw materials are made into electrodes to be smelted; 2, a titanium alloy cast ingot is subjected to air cooling after heat preservation and forging; 3, a first forging stock titanium alloy is subjected to air cooling after heat preservation and forging; 4, a second forging stock titanium alloy is subjected to air cooling after heat preservation and forging; 5, a third forging stock titanium alloy is subjected to heat preservation and then water cooling; 6, the water-cooled titanium alloy forging stock is subjected to heat preservation and shaping after forging; and 7, a plate blank is subjected to solution aging treatment and machining, and the medium-strength and high-toughness titanium alloy medium-thickness plate is obtained. According to the short-process preparation method for the medium-stren
