Abstract

a. Procédé pour effectuer des études de fusion et solidification à l'abri de forces et sans contacts. b. Procédé caractérisé en ce que l'échantillon, pendant toute l'opération de fusion y compris, le refroidissement qui suit, est observé et surveillé au moyen d'organes de mesure fonctionnant sans contacts en ce qui concerne sa position à l'intérieur du four, et des signaux de commande sont envoyés par ces organes de mesure dans le cas de déviations de l'échantillon par rapport à sa position prescrite à l'intérieur du four. c. L'invention s'applique notamment à la fusion de métaux.
