A Study of Manufacturing Process of Titanium Clad Steel

摘要

It is well known that to produce titanium clad steel by hot rolling process is quite difficult because of harmful TiC or Ti-Fe type intermetallic compounds layers at the bonded boundary. These harmful layers bring about the decreases of the bonding strength and the quality of joints. These harmful layers ore formed by diffusion of the C and Fe elements at high temperature. In order to ovoid the formation of them, there are two effective method which are the use of insert metal like Cu, or sometimes Ni, and the decreases of hot rolling and annealing temperature. The method of using insert metal has already confirmed by many researchers, but the method of controlling the productive temperature has not enough yet. This paper shows the systematic experiments on hot rolling and cold rolling process. As a result, the suitable controls of hot rolling and annealing temperatures are confirmed to be quite effective to diminish the harmful layer and to be contributed to improve the quality of bonding.
