Abstract

έθοδος εξαλείψεως των παραμενουσών τάσεων των βαφέντων κραμμάτων, μέσω μιας αναστρόφου βαφής, ήτοι μιας βιαίας επαναθερμάνσεως, κατά την διάρκειαν της οποίας, η εξωτερική περιοχή του τεμαχίου, ευρίσκεται θερμοκρασιακώς υψηλότερον, της εσωτερικής περιοχής, χαρακτηριζομένη εκ του ότι η θέρμανσις επιτυγχάνεται δι' επαγωγής εντός ενός πολύ βραχέως χρόνου μέσω ενός επαγωγέως υψηλής συχνότητος, του οποίου η ειδική επιφανειακή ισχύς περιλαμβάνεται μεταξύ 0,5 και 2 KW περίπου ανά τετραγωνικόν εκατοστόμετρον επιφανείας του κατεργαζομένου τεμαχίου και ότι μετά την θέρμανσιν ταύτην επαναψύχεται το τεμάχιον, είτε εις τον αέρα ηπίως, είτε δι' ύδατος, μεταξύ 10 και 40 λεπτών μετά το πέρας της θερμάνσεως δι' επαγωγής. method of eliminating the residual stresses of the dyed alloys by means of a reverse dyeing, i.e. a violent reheating, during which the outer region of the workpiece is at a higher temperature than the inner region, characterized in that the heating is achieved of a very short time by means of a high frequency inductor, the specific surface power of which is between approximately 0.5 and 2 KW per square centimeter of surface area of the workpiece and after which heating the workpiece is re-cooled, either in gentle air or by air. water, between 10 and 40 minutes after the end of induction heating.
