PREPARATION METHOD OF TITANIUM/IRON ALLOY CLAD SHEETS

摘要

PURPOSE: A preparation method of titanium/iron alloy/titanium clad sheets is provided to be economical at the low temperature and to prevent the physical property of titanium from deteriorating in preparing the titanium/iron alloy clad material. CONSTITUTION: The preparation method of titanium/iron alloy/titanium clad sheets comprises the steps of: inserting aluminum or aluminum alloy sheets between iron alloy sheets and titanium sheets and laminating; bonding by hot rolling the laminated sheets under the air without an atmospheric gas at 200 to 450 deg.C; and diffusion treating the inserted aluminum of the bonded sheets at 250 to 450 deg.C. The titanium/iron alloy/titanium clad sheets comprise aluminum or aluminum alloy as an intermediate material between titanium and iron alloy.
