摘要

The Droplet Emulsion Technique (DET) is used to produce AL master alloy dropletdispersions that contain incorporated inoculant particles. In order to identify inoculants of variable potency contained in commercial grain refining alloys, droplet quenching treatments are used to preserve microstructures associated with the nucleation and growth of Al from the most effective inoculant particles. The use of the methods shows that a commercial Al-6wt % Ti master alloy contains a minor fraction (1-2%) of effective (Al, Si)3Ti inoculant particles are structurally identical, but chemically dissimilar to a vast majority of less potent Al3Ti particles. The identification of (Al,Si)3Ti as an effective agent for Al grain formation has lead to an analysis of the Al-Ti-Si ternary system. Evaluation of pertinent phase equilibria and Al-inoculent disregistry has shown
