ABSTRACT:
The present invention provides a method for producing an aluminum alloy which includes the step of carbothermically reducing an aluminous material to provide an alloy consisting essentially of the formula Al.sub.bal TM.sub.d Si.sub.e, wherein TM is at least one element selected from the group consisting of Fe, Ni, Co, Ti, V, Zr, Cu and Mn, "d" ranges from about 2-20 wt %, "e" ranges from about 2.1-20 wt %, and the balance is aluminum and incidental impurities. The alloy is placed in the molten state and rapidly solidified at a quench rate of at least about 10.sup.6 K/sec to produce a rapidly solidified alloy composed of a predominately microeutectic and/or microcellular structure.
