Abstract
An internal friction study was conducted into the strengthening mechanism of low-temperature, paraequilibrium, carburization of stainless steel. Low temperature carburization of stainless steels results in hard surfaces with high residual compressive stresses that have excellent corrosion and fatigue resistance. an internal friction peak is reported that is indicative of a strain field with tetragonal symmetry consistent with the formation of carbon interstitial pairs. It is concluded that the formation of these defects is responsible for the mproved properties of stainless steels treated in this manner.
