Corrosion at Sulphide Inclusions in Stainless Steel

Auger analysis was performed using a high resolution scanning auger electron microscope and auger electron spectroscopy. Elemental auger contour maps for corroded sulphide inclusions in stainless steel were presented. It was found that the copper enriched-manganese sulphide inclusions were uniformly corroded, which might be due to CU2S deposition on the surface of corroding inclusions. In contr...

State of the Art in the Control of Inclusions during Steel Ingot Casting

This article extensively reviews published research on inclusions in ingot steel and defects on ingot products, methods to measure and detect inclusions in steel, the causes of exogenous inclusions, and the transport and entrapment of inclusions during fluid flow, segregation, and solidification of steel cast in ingot molds. Exogenous inclusions in ingots originate mainly from reoxidation of th...
