Abstract
A metal foam object results from the mixing of a gasifier with metal powder and subjecting the mixture to an elevated temperature T and pressure P to form a sintered sheet placing at least a portion of the sintered sheet into a mold and subjecting the mold to a temperature T where T is greater than T at which the metal melts and the gas is released from the gasifier and quenching the metal foam object thus formed in the mold. The quenching is carried out by applying a cryogen to the object as a high velocity mixture of gas and liquid droplets.
