논문 초록 (Abstract)

• A functionally graded material was fabricated with a compositional range of Inconel 718 and stainless steel 316L. • Defects were found in the 25 wt% Inconel 718/75 wt% stainless steel 316L region. • Various precipitates at the interfacial boundaries caused the defects. • Constitutional supercooling and columnar-to-equiaxial transition affected the formation of the defects. • The defective compositional range was removed to improve the mechanical reliability of the functionally graded material.
