Cladding Metals by Continuous Strip Rolling in Vacuum.
MISSING :11 pages
Equipment and procedure for the continuous roll bonding of metal strips are described. The reels, mill rolls, and furnace were located within a vacuum chamber capable of operation at a residual gas pressure of 1 x 10-4 to 1 x 10-5 torr. Several metals were successfully clad at rolling temperatures of 930 deg. to 1,050 deg. C in lengths up to 120 ft. The bimetals that were clad included stainless steel to carbon steel, molybdenum, and nickel to stainless steel and carbon steel, and titanium to carbon steel. Bend tests of bond integrity are described, and microstructures of the interfaces are presented. The amounts of brittle intermetallic phases formed at the interface are minimized by this cladding method.
