“…8, indicating the beginning of the chromium carbide precipitation at d/g interfaces during aging at temperature ranging from 550 to 700 C. Therefore, the d-ferrite Table 2. The decomposition products of the d-ferrite during aging have been reported in previous studies related to austenitic stainless steels with low ferrite content [27,31,34,46,51] and to duplex stainless steels [42,52]. This decomposition depends mainly on the chemical composition of the material and on aging temperature.…”

“…Stabilizing elements extremely enhances the creep strength by promoting the formation of fine intergranular carbides. Niobium to be a strong former of Nb (C, N) carbonitrides can block the formation of chromiumrich carbide at grain boundaries accompanying chromiumdepleted zones [1] and hence improve intergranular and pitting corrosion resistance during aging process [6,20,21]. As regards to heat treatment of ASSs, solution heat treatment is used in order to decrease the susceptibility to intergranular corrosion by solubilizing the chromium-rich carbide [6].…”

In this study, 316Nb stabilized austenitic stainless steel pieces were produced via sand and centrifugal casting method in order to be investigated. Heat treatments were done in two stages, and cooling was made in various quenching mediums. As-cast parts and the parts with only the highest and the lowest tensile strength were investigated. Metallographical analyses were made and the content of non-metallic inclusions was examined. Various types of carbides in microstructures were determined by means of SEM-EDX analysis. The sand casting samples had more non-metallic inclusions than the centrifugal casting ones. After the tensile tests, it was seen that these inclusions had significant effect on the mechanical properties. The tensile strength, the yield strength, the elongation and the hardness values of the centrifugal casting samples were higher than the sand casting ones. Investigating the SEM-EDX analyses, it was determined that the sand cast samples had chromium carbides in small quantities, in addition to niobium carbides. Centrifugal cast parts had niobium carbides.
