Abstract
Forged and flat-bar rolled SKD11 tool steels are known to show anisotropic dimensional change during heat treatment. In this study, the continuous dimensional change and the anisotropic behavior of SKD11 tool steel during austenitizing and tempering heat treatment have been investigated by dilatometry. Anisotropic dimensional change occurs not during heating but mostly during cooling, and it increases with increasing austenitizing temperature. Anisotropic dimensional change of SKD11 tool steel was mainly attributed to large elongated carbides produced during rolling process. Using dilatometric and metallographic examination, the possible mechanism of the anisotropic dimensional change has been discussed.
