Metal powder compositions for pressed powder metallurgy, and methods of forming metal parts using the metal powder compositions. The metal powder compositions include a metal powder and a lubricant system, which are pressed to form a green compact. When the green compact is heated during a delubing process, the lubricant system provides a reactive carbon coating on the surface of the metal powder, which upon subsequent sintering, reacts with metal oxides present on the surface of the metal powder to form gas that is easily removed from the system. Removing the metal oxides from the surface of the metal powder provides a more dense metal part, and allows for sintering of the green compact without the need for hydrogen gas, which would otherwise be needed to remove the metal oxides on the surface of the metal powder.
