A magnetorheological material containing iron alloy particles demonstrates magnetorheological strength dependent upon the elements of the alloy and relative concentration of the alloy elements. Selected iron/cobalt alloys demonstrate improved yield strength over traditional carbonyl iron based MR materials when the iron-cobalt alloy has an iron-cobalt ratio ranging from about 30:70 to 95:5. The iron-nickel alloys which have an iron-nickel ratio ranging from about 90:10 to 99:1 maintains superior strength over iron-nickel alloys outside that range.

Cobalt And Nickel

The self-diffusion of nickel and the diffusion of Ni63 into iron, cobalt, and two iron–nickel alloys was studied using the technique of decrease in surface activity, The nickel self-diffusion results are compared to previously reported values. Nickel is found to diffuse more slowly than iron in the iron-rich portion of the iron–nickel system. The rate of nickel diffusion increases with increasing nickel content. A comparison is made between the present results for diffusion of Ni63 into iron, cobalt, and nickel with reported values for diffusion of Co60 and Fe59 in the same metals. In each solvent, the magnitudes of the activation energies, Q, are such that QNi > QCo > QFe.

Abstract The 50 Nickel-Iron Alloy is recommended for glass-to-metal seals. It is used with such glasses as Types 0120 and 9010 that have higher than normal thermal expansion and with certain ceramics. It is used in a number of applications where expansion must be almost linear to 1000 F. The 50 Nickel-Iron Alloy has relatively good mechanical properties; in fact, at room temperature it has a tensile strength of 80,000 psi and an elongation of 35%. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-276. Producer or source: Mills that produce iron-nickel alloys.

Abstract The 42 Nickel-Iron alloy has the lowest expansivity of the Iron-Nickel alloys that are commonly used for glass-sealing applications. Its thermal expansion closely matches the 1075 glass and it is sometimes used for sealing action with the 0120 and 0010 glasses. It is made close metallurgical control to provide uniformity of performance. Its many uses include industrial lamps, ceramic-to-glass seals, and sealed-beam automobile headlamps. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Fe-66. Producer or source: Iron-nickel alloy mills.
