METHOD FOR CONTROLLING VARIATION OF GRAIN REFINING ABILITY OF AL-TI-B ALLOY BY CONTROLLING COMPRESSION RATIO

摘要

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.
