Abstract
A method for controlling variations of Al—Ti—B alloy crystal grain refinement ability through controlling a compression ratio of sectional area of Al—Ti—B alloy including: A. establishing a relationship between variations of refinement ability of Al—Ti—B alloy crystal grain and parameters of press process of the Al—Ti—B alloy; setting the parameters of press process and controlling the variation of the refinement ability of the Al—Ti—B alloy crystal grain through controlling a value of the compression ratio.
