Summary:The invention relates to a forging method for reducing the forging temperature of a TC4 alloy blade, which is used for solving the technical problem of high forging temperature of a traditional TC4 titanium alloy. The invention has the technical scheme that the forging method comprises the following steps of: carrying out solid hydrogen distributing treatment on the TC4 alloy; machining the obtained solid hydrogen distributing titanium alloy blank after treatment into a solid hydrogen distributing titanium alloy prefabricated blank; blowing sand and polishing; spraying a lubricating agent; mounting a die and preheating; forging the solid hydrogen distributing titanium alloy prefabricated blank to obtain a solid hydrogen distributing titanium alloy blade forging piece; removing flash; blowing sand and polishing; and removing hydrogen. The TC4 titanium alloy is subjected to solid hydrogen distributing treatment, so that the forging temperature of the TC4 titanium alloy is reduced to 720-780DEG C from 800-982DEG
