ABSTRACT:
A process for preparing a slurry structured metal composition comprising degenerate dendritic solid particles contained within a lower melting matrix composition, the process comprising vigorously agitating at a given shear rate molten metal as it is solidified. Greatly improved processing efficiencies result if the shear and solidification rates are adjusted so that the ratio of the shear rate to the solidification rate is maintained at a value ranging from 2.times.10.sup.3 to 8.times.10.sup.3.
