strength and hardness. After sintering the part is often reheated to allow quenching, then tempered to further increase hardness and strength. Sintering of iron-based PM parts is usually done at around 2020-2100°F. Sintering is a process of diffusion bonding. Below a material's melting point, adjacent grains of metal begin to share molecules.
Permanent magnets (PMs) produce magnetic fields and maintain the field even in the presence of an opposing magnetic field.
