The Stabilization of Austenite by Hydrogen in Two Tool Steels

Pages 483-491 | Published online: 18 Jul 2013
 

Abstract

The results of some investigations on the stabilization of austenite by hydrogen in two tool steels are reported in this paper. It is shown that hydrogen stabilizes the austenite if introduced cathodically at appropriate stage. Cathodic impregnation is shown to be essential for such stabilization. It has also been shown that the quantity of hydrogen required for stabilizing the austenite need not be large, if the manner of its introduction into the austenite prior to transformation is appropriate.

Résumé

Nous présentons ici les résultats des quelques recherches sur la stabilisation de l'austénite par l'hydrogène dans deux aciers à outils. Il est montré que l'hydrogène stabilise l'austénite s'il est introduit cathodiquement à un stade approprié. Et l'on montre que l'imprégnation cathodique est essentielle à une telle stabilisation. On a également montré que la quantité d'hydrogène requise pour stabiliser l'austénite n'a pas besoin d'être importante, si la façon dont elle a été introduite dans l'austénite avant transformation est appropriée.
