Corrosion Behavior of Alumina-Aluminum and Silicon …

Pits in the silicon carbide (SiC) composites were deeper than those in the alumina (Al 2 O 3) composites, probably because the SiC particles acted as efficient hodic sites. Pit initiation and propagation occurred at weak spots in the air-formed film, corresponding to phase discontinuities and second-phase particles and to oxygen reduction at the particles or precipitates.

Influence of Carbide-Promoting Elements on the …

Because of its low cost, steel scrap is one of the most important raw materials for the production of ductile iron (DI). The amount of carbide-promoting elements in steel scrap, such as chromium, manganese, molybdenum, niobium and vanadium, is expected to increase in the future. Most of these elements have a negative impact on the microstructure and mechanical properties of DI. The solubility
