The addition of molybdenum, nickel, and copper to iron improves the hardenability of steel. These materials are easily sintered in a number of different atmospheres due to the easy reduction of the oxides of both elements, resulting in their preeminent position in PM alloys for strengthening steel. The chemical elements may be fully prealloyed in the powder, blended from elemental components, or a hybrid of partially prealloyed powder mixed with elemental additions. Elemental additions may be as-blended or diffusion-bonded together for ease of processing. The materials may be used as-sintered with slower cooling, or heat treated for higher strength and hardness. In some cases, rapid cooling during sintering can produce sinter-hardened structures to provide the strength and hardness required without resorting to a secondary heat treat process.
