, La taille moyenne des précipités ?' après le traitement optimisé devient presque identique si comparée entre les coeurs dendrites et les espaces interdendritiques respectivement pour chaque alliage. On peut aussi remarquer une diminution de la taille moyenne et une diminution de la largeur de la distribution des précipités ?' entre l'état initial et l'état optimisé. On peut donc confirmer que l'état optimisé présente une distribution plus homogène, Une grande disparité de taille des précipités ?' entre les coeurs de dendrites et les espaces interdendritiques pour les deux alliages dans l'état initial est observée

A. Figure, 1 -Distributions de la taille des précipités ?' avec un fit par une loi normale dans les coeurs de dendrites (D, trait plein) et dans les espaces interdendritique (EI, trait en pointillés) pour les états de traitement thermique initial (ini) et optimisé (opti) pour : (a) le CMSX-4

, Cas du CMSX-4 Plus par deux fondeurs différents

, On peut cependant noter, que la taille moyenne des précipités ?' dans l'alliage élaboré par le fondeur A est légèrement supérieure à la taille moyenne des précipités dans l'alliage élaboré par le fondeur B, dans les coeurs dendrites et dans les espaces interdendritiques. De même, La Figure A4.2 présente la distribution de taille des précipités ?' déterminée par analyse d'image
