... Abstract Both surface finish and surface integrity must be defined, measured, and maintained within specified limits in the processing of any product. Surface texture is defined in terms of roughness, waviness, lay, and flaws. This article illustrates some of the designations of surface...

In this case, however, cavity outlines were masked by the slip steps created on grain boundaries due to severe plastic deformation within the grains. The wavy nature of the slip lines is a characteristic of body-centered cubic...

A technique for obtaining better surface finish that is currently being used in many automotive applications is called in-mold coating. To apply an in-mold coating, a thermoset resin is injected into the mold after the SMC component is partially...
