Cladding of Metals to Iron by Vacuum Rolling

摘要

To investigate cladding, a vacuum-rolling mill capable of rolling bimetal specimens at temperatures to 1,300 C in a residual gas pressure of 2 x 0.00002 torr was established. Metals that were successfully bonded to iron included stainless steels, chromium, nickel, nickel alloys, copper, and several refractory metals including molybdenum and titanium. The effects of the rolling temperature, reduction in thickness, rolling speed, and residual air pressure on bonding strength and bend ductibility of the bimetals were determined. Optimum rolling conditions produced bimetals with bond shear strength essentially equal to that of the iron base metal.
