Abstract
Metal particles are intimately mixed with at least about 1.5 wt. percent of an organic binder. The mixture is poured into a thermally degradable mold and heated to above sintering temperature to form a preform useful for hot forging. The mold provides integrity for the packed particles until the organic compounds carbonize, which in turn effect sufficient bonding until the particles actually sinter together.
