By experimental research on the superhard aluminum alloy 7175T74, the parameters of forging process of 7175T74 are given, which achieve the mechanical property of the of U. S. 'AMS4149A.
In order to keep the property of forging pieces which they already have, calibrating in the way of cold correcting the shape with stress release and tempering could get a better result.
