Definitions

  • the invention relates to the use of a soft magnetic, heat-hardenable Ni-Fe alloy for relay parts with additives made of one or more of the elements titanium and niobium, which can contain conventional deoxidation additives and normal melt impurities.
  • nickel-iron alloys with a nickel content between 35 and 40% nickel are also used for those relay parts in which the magnetic properties play less of a role than the processability of the material.
  • the object of the present invention is to provide an alloy range within the alloy system with the main elements nickel and iron, which brings a further decisive improvement to the alloys used for relay parts with regard to this purpose.
  • the combination of certain areas in the nickel content together with corresponding areas in the additives for hardening niobium and titanium can at the same time, according to the invention, result in a high saturation induction at the same time, high Vickers hardness and sufficient permeability for the sensitivity of the relay in the range from 25,000 to 30,000 ⁇ max specify a sufficiently soft magnetic material with a coercive field strength below 0.15 A / cm.
  • relay parts can be specified for relays with a very long service life, which generate relatively high forces with low excitation due to their high maximum induction and do not require a wear-resistant coating on the mechanically stressed surfaces.
  • the solution according to the invention is that in order to achieve a saturation induction above 1.0 Tesla with a simultaneously high Vickers hardness above 150 HV, an alloy with in% by weight: 40-55% Ni, 0.5-6% Ti and 0-5% Nb with the Provided that the proportion of Ti + Nb together is greater than 1%.
  • the measurement samples were taken at 19.5 mm in the hard-rolled state with a final deformation of about 70%.
  • the measurement of the magnetic properties such as coercive force, permeability and induction values, was carried out on solid rings, the measurement of the mechanical properties including the hardness on proportional rods made from the drawn material.
  • the solid rings were subjected to an annealing treatment at a temperature of 1150 ° C. for 4 hours and then cooled with normal furnace cooling. This was followed by a tempering treatment for curing at 650 ° C. with rapid cooling in a cold trap.
  • Table 1 below shows the compositions of the sample alloys in accordance with batch no. 81/8476 to 84/8529.
  • Table 2 shows for the same batch number.
  • Ni (total) 45.5 (100-Ni (Ni3Ti) -Ti (Ni3Ti)) 100 + Ni (Ni3Ti) ⁇ 1% by weight.
