Abstract

L'invention concerne un outillage (200) destiné à supporter pendant un traitement thermique une préforme (210) de pièce obtenue après la mise en forme d'une poudre métallique ou céramique, l'outillage comprenant un plateau (220), et une pluralité de blocs (230) disposés sur le plateau et ayant au moins une surface (230a) destinée à supporter la préforme. Au moins une partie des blocs sont reliés entre eux par au moins un élément d'entraînement (240), ledit élément d'entraînement comprenant une poudre métallique ou céramique mélangée à un liant organique et étant apte à se rétracter sous l'effet de la température de manière à entraîner ladite au moins une partie des blocs auxquels il est relié dans une ou plusieurs directions correspondant à une ou plusieurs directions de rétractation de chaque élément d'entraînement. L'invention vise aussi un procédé de traitement thermique d'une préforme mettant en œuvre un tel outillage.
