Marquenching

A form of heat treatment applied as an interrupted quench of steels typically in a molten salt bath at a temperature right above the martensite start temperature. This is used to delay the cooling to equalize the temperature throughout the piece, minimizing distortion, cracking, and residual stress and is a good choice for parts that are sensitive to deformation during the cooling process.
