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

摘要

A method for controlling variation of grain refining ability of Al-Ti-B alloy by controlling compression ratio comprises: constructing a function about variation of grain refining ability of Al-Ti-B alloy and processing parameters of press working, and controlling variation of grain refining ability of Al-Ti-B alloy precisely by controlling compression ratio precisely at given processing parameters of press working.
