Elimination of casting heterogeneities by high temperature heat treatment on a titanium stabilized austenitic alloy. Effect on the microstructure
Description
Microstructural observation on a longitudinal section of stainless steels often reveals the presence of a ''veined'' structure showing a segregation remainder due to the setting of the ingot. This casting heterogeneity can be eliminated by high temperature treatments. This study shows the change in the structure and the state of solubilization produced by these high temperature treatments and the effect of a stabilizing element such as titanium on Z6CNDT17.13 and Z10CNDT15.15B alloys compared with the Z6CND17.13 alloy. It is also shown that a high temperature treatment applied to these stabilized alloys deeply modifies the recrystallization kinetics

L'observation microstructurale sur une coupe longitudinale d'aciers inoxydables montre tres souvent la presence d'une structure ''veinee'' traduisant un restant de segregation du a la solidification du lingot. Cette heterogeneite de coulee peut etre eliminee par des traitements a haute temperature. Cette etude montre l'evolution de la structure et de l'etat de solubilisation produits par ces traitements a haute temperature et l'influence d'un element stabilisant tel que le titane sur les alliages Z6CNDT17.13 et Z10CNDT15.15B, compares a l'alliage Z6CND17.13. Nous montrons egalement qu'un traitement a haute temperature effectue sur ces alliages stabilises modifie profondement la cinetique de recristallisationFiles
