Abstract

Abstract Alloy X12CrNiWTi1613 is an alloy developed specifically for high temperature applications. The alloy is of an austenitic stainless steel type, containing the carbide formers, W, Ti and Mo, ordered according to their weight percent. However, the literature does not include much data regarding carbide morphology and identification for this type of steel. The aim of this work is to identify the type and morphology of the carbides that form in this alloy after aging heat-treatment. Three shapes of carbides; globular, rod-like, and small round, were found to be present of the types (TiWMo)C, Ti(C,N), and TiC or TiWC.
