Abstract

A number of researchers have suggested that there may be phase relationships in the Al-Ti-B system, which can be used to explain why boron improves the grain refining ability of aluminum-titanium master alloys. In this paper, the available information on the phase diagram is reviewed and theoretical calculations are made to establish the ternary Al-Ti-B phase diagram. The phase diagram cannot explain the important effect of boron. It appears to be necessary to seek another explanation.
