Abstract
A work piece in a hot gas isostatic bonding furnace is cooled by increasing convection within the furnace prior to depressurizing. The convection may be wholly due to thermal gradients or may be supplemented by a compressor. The cooling jacket for the furnace walls may supply the entire cooling or may be supplemental heat exchanger. The quenching takes place within the furnace without changing the atmosphere.
