Abstract

Preferred embodiments of the present invention include methods that allow for casting alloys, and preferentially casting wrought alloys to circumvent problems such as, for example, hot tearing. Preferred embodiments of the present invention provide for alloys having predominantly spherical primary α-aluminum grains in their microstructure (i.e., substantially free of dendrites) formed by mixing two liquids of differing compositions that are held at predetermined temperatures, such that when mixed they produce a predetermined alloy composition at a predetermined temperature that is inclined to solidify with a predominantly spherical grain structure that minimizes the alloy's tendency towards hot tearing.
