Corrosionpedia - What are Inclusions? - Definition from , 18crnim07 6 oxide inclusions

Inclusions involve the addition of substances like oxide and thiosulfate to initiate or test the early growth of corrosion or fatigue cracks. Such inclusions promote test conditions where the effects of corrosion of materials are analyzed. In cases of oxide inclusions, fatigue Prediction of Reoxidation Inclusion Composition in Reoxidation inclusions are the most common form of inclusions that are found in steel castings. They account for approximately 83% of the inclusions in carbon and low-alloy steel castings, and approximately 48% of the inclusions in high-alloy and stainless steel castings (Griffin and Bates, 1991).Micromechanical analysis of gear fatigue-ratcheting damage , 18crnim07 6 oxide inclusionsDespite the fact that high-quality steels are manufactured in recent years, non-metallic inclusions such as Al 2 O 3 are still inevitable during steel manufacturing process. Early failures of bearings and gears are widely associated with the non-metallic inclusions, especially in some heavy duty machines such as wind turbines, ships and high-speed rails.

Slag inclusions are usually associated with the flux processes, ie MMA, FCA and submerged arc, but they can also occur in MIG welding. Causes As slag is the residue of the flux coating in MMA welding, it is principally a deoxidation product from the reaction between the flux, air and surface oxide.Effect of Sulphur Concentration on Precipitation Behaviors , 18crnim07 6 oxide inclusionsThe Effect of Sulphur Concentration on Precipitation Behaviors of Oxide-sulphide Complex Inclusions Seen from Table 4 , the main inclusions are oxide-sulphide complex inclusions in the samples.
