    摘要： A thermostatic biemetal having a relatively high deflection is disclosed. The bimetal comprises as a high expanding side a manganese-nickel-copper alloy having specific ranges for nickel and the combined total of copper and one-half the nickel content is also within specific limits. The low expanding side is a nickel-iron-cobalt alloy with controlled amounts of manganese carbon and silicon.

    摘要： A process is disclosed for producing a composite strip consisting essentially of a stainless steel layer and a brazing alloy layer metallurgically bonded together along a common interface. The process comprises heating under pressure a package consisting of a plate of stainless steel and a plate of the primary brazing alloy containing a thin foil of a second brazing alloy at the mutual interface of the stainless steel and primary brazing alloy to a temperature above the melting point of the second brazing alloy but below the melting point of the primary brazing alloy and below the recommended hot working temperature of the stainless steel, lowering the temperature of the package while still under pressure below the melting point of the second brazing alloy, removing the pressure and further lowering the temperature of the now bonded package below 900*F and above the martensitic transformation temperature, reducing the thickness of the package to a strip at temperatures above the martensitic transformation, and cooling the strip to ambient temperature. Alternatively, the process can comprise heating the steel alone to a temperature above its recommended solution heat treatment temperature, lowering the temperature to slightly above the melting point of the primary brazing alloy, applying under pressure a plate of the primary brazing alloy without the second lower melting brazing alloy lowering the temperature of the package under pressure after partial melting of the brazing alloy at the interface below the melting point of the brazing alloy, removing the pressure and further lowering the temperature of the new bonded package below 900*F and above the martensitic transformation temperature, reducing the thickness of the package to a strip at temperatures above the martensitic transformation, and cooling the strip to ambient temperature.
