A rapid cooling method for metal parts, using a pressurized cooling gas, characterized in that the cooling gas comprises one (or several) principal gas(es) absorbing infra-red radiation, selected in such a way as to improve thermal transfer to the part by combining radiative and convective transfer pheonomena in order to optimize the convective transfer coefficient.
Un procédé de refroidissement rapide de pièces métalliques à l~aide d~un gaz de refroidissement sous pression, se caractérisant en ce que le gaz de refroidissement comprend un (ou plusieurs) gaz principal absorbant le rayonnement infra-rouge, choisi de façon à améliorer le transfert thermique à la pièce en conjuguant les phénomènes de transferts radiatif et convectif, et de façon à optimiser le coefficient de transfert convectif.
