The demand for cleaner steels increases every year. In addition to lowering non-metallic oxide inclusions and controlling their size distribution, morphology, and composition, clean steel requires control of sulfur, phosphorus, hydrogen, nitrogen and even carbon, and minimizing metallic impurity elements such as As, Sn, Sb, Se, Cu, Zn, Pb, Cd, Te and Bi. These requirements vary with steel grade...
Non-metallic inclusions and twin boundaries are preferred fatigue crack nucleation locations in polycrystalline Ni-based superalloys. A Heaviside HR-DIC, EBSD multi-scale modelling strategy (CPFE-DDP) was used to assess experimental observations of near agglomerated RR1000 at elevated temperature. Inclusion fracture decohesion were observed within the first cycle loading. Fatigue non-metallic i...
The secondary-phase particles in metals, particularly those composed of non-metallic materials, are often detrimental to the mechanical properties of metals; thus, it is crucial to control inclusion formation and growth. One of the challenges is determining the three-dimensional morphology and inner structures of such inclusions. In this study, a non-aqueous solution electrolytic method and a r...
