Abstract
A process for consolidating powder, particulates, foils or sheets of metal coated composites, elemental metallic or metallic alloy or intermetallic compounds into net shapes having increased green strength at or near ambient temperature comprises treating the material with an aqueous activation solution. The aqueous activation solution is selected from dilute acids, reducing agents, molten salt electrolytes and mixtures thereof. Pressure is used to consolidate the treated powders, particulates, foils or sheets into a net shape at or near ambient temperature.
