Grain Refinement of Aluminum and Aluminum Alloys by Sc and Zr

Rare earth elements and transition are widely used in aluminum alloys, magnesium alloys copper due to their unique microalloying effects. With regard in-depth research on the grain refinement characteristics of rare elements, combination master has a great impact theories technical refinement, broadening application field alloys. This paper first summarizes mechanisms analyzes effects suitable for preparation Al-M mechanism.
