METAL PROCESSING METHOD AND METAL PRODUCT PROCESSED THEREBY

摘要

A metal processing method using a tailored blank material as a raw material comprises: preliminarily bonding together a metal material having a relatively high heating rate by infrared heating and a metal material having a relatively low heating rate by infrared heating, to form an integrated metal material; and a-heating step the integrated metal material, wherein infrared heating of the integrated metal material is performed by infrared simultaneously and comprehensively; and in the integrated metal material undergoing the infrared heating, the infrared heating is terminated after a portion having the relatively high heating rate reached a predetermined temperature corresponding to a predetermined heat treatment and before a portion having the relatively low heating rate reaches the predetermined temperature.
