WebJan 1, 1993 · The more prevalent inclusions are insitu, which form as a result of a chemical reaction within the metal handling system. Insitu inclusions are formed by oxidation, aluminum carbide and halide salts. These formation mechanisms, however, can be avoided by paying attention to practical rules.
WebJul 14, 2024 · There are four types of inclusions in wrought superalloys: ceramic oxide inclusions, Al 2 O 3, MgO, etc.; carbide, nitride, sulfide, and other non-metallic inclusions, such as TiC, TiN, Ti (C,N) and CeS; composite inclusions, such as Al 2 O 3 ·MgO–TiN; and dissimilar metal inclusions, mainly Nb and Cr. An inclusion is a solid particle in liquid aluminium alloy. It is usually non-metallic and can be of different nature depending on its source. Inclusions can create problems in the casting when they are large and in too high concentration.
