Abstract
In manufacturing processes white layers can occur in the surface zones of hardened workpieces due to excessive mechanical and thermal loads of the material. The characteristics of these white layers are discussed contradictorily in literature. In this paper a new approach to characterize the crystallographic structure of white layers is presented. Specimens manufactured by grinding, hardturning and laser machining are analysed. Several analytical methods are used and the resultant characteristics of these methods are compared. It is shown that the white layers which occur after grinding and laser machining consist of about 90 % tetragonal martensite and 10 % retained austenite.
