Abstract
This paper describes the properties of 48 to 57% Ni-Fe alloys with up to 2.1% Ti. The precipitation hardenable Fe-Ni-Ti alloys are considerably stronger than the conventional 52 Ni alloy presently used in dry reed switches and thereby may be of value in reducing failures due to bending of the wire and associated glass breakage. Thermal expansion, electrical resistivity, and magnetic properties as well as tensile properties are presented as a function of both Ni and Ti contents of the alloys. Three aging temperatures (650, 700, 750°C) were used. Regression equations have been developed to describe the results within the indicated compositional limits for a selected aging treatment.
