Outline of Final Research Achievements

A method of local hardening of steel die using rapid resistance heating is a local hardening method newly devised by focusing attention on unique characteristic of Joule heating at the electrode contact area in the resistance heating and considering its application to heating for local quench hardening of steel. The development research done for realization of the method by considering concrete measures against technical problems in its practical application made it appear that the local hardening is possible by setting the electrification condition suited to respective applications. All the findings obtained through this work were made public at relevant domestic and international conferences.
