    摘要: A thermocouple bimetal of the type made from a metallic component of high thermal expansion which is bonded to a component of low thermal expansion and in which said component of low thermal expansion consists of a thermally age-hardenable iron-nickel-titanium alloy with 26 to 55% nickel, 1-5% free titanium, 0-16% cobalt, remainder iron including impurities conditioned by the melt, and said component of high thermal expansion consists of a thermally age-hardenable iron-nickel-manganese-titanium alloy with 14-26% nickel, 3-10% manganese, 1-5% free titanium, remainder iron including impurities conditioned by the melt. An advantageous method of producing such a bimetal is also described.

    摘要: A RELATIVELY LOW COST, MULTI-LAYER COMPOSITE THERMOSTAT MATERIAL IS DISCLOSED HAVING PRESELECTED ELECTRICAL RESISTIVITY AND FLEXIVITY CHARACTERISTICS INCLUDING FIRST AND SECOND OUTER LAYERS OF METALLIC ALLOYS HAVING RELATIVELY HIGH AN RELATIVELY LOWER COEFFICIENTS OF THERMAL EXPANSION AND AN INTERMEDIATE A LAYER OF A FERROUS ALLOY. THE FIRST OUTER LAYER OF METALLIC ALLOY COMPRISES A MATERIAL COMPRISING BY WEIGHT APPROXIMATELY 71% TO 76% MANGANESE, 9% TO 19% COPPER, AND 9% TO 17% NICKEL, WHILE THE SECOND OUTER LAYER COMPRISES A METALLIC ALLOY SUCH AS THE MATERIAL COMMONLY REFERRED TO AS INVAR, WHICH COMPRISES BY WEIGHT APPROXIMATELY 35 1/2% TO 36 1/2% NICKEL AND THE BALANCE IRON. THE FIRST AND SECOND OUTER LAYERS ARE METAL-

    LURGICALLY BONDED TO RESPECTIVE OPPOSITE SURFACES OF THE FERROUS INTERMEDIATE LAYER. THE VARIOUS LAYERS COMPRISING THE COMPOSITE MATERIAL COOPERATE TO DEFINE AN EXTREMELY ECONOMICAL, COMPOSITE THERMOSTAT MATERIAL HAVING RE SISTIVITY CHARACTERISTICS SUITABLE FOR MANY APPLICATIONS, WHILE HAVING REQUISITE CHARACTERISTICS OF FLEXIVITY, USEFUL DEFLECTION TEMPERATURE RANGE, STRUCTURAL STRENGTH AND ABILITY TO WITHSTAND HIGH TEMPERATURES COMPARABLE TO PREVIOUSLY AVAILABLE THERMOSTAT MATERIALS ONLY OBTAINABLE AT SUBSTANTIALLY HIGHER COSTS.
