抄録

Masumoto et al. previously discovered that alloys near the composition of Ni3Mn exhibit high permeability by optimum heat treatments, and named them “Nimalloy”. Subsequent studies of the authors on various element additions on the properties of Ni-Mn alloys have revealed that the highest initial permeability of 76000 and the highest maximum permeability of 441000 can be obtained in Ni-Mn-Fe-Cr alloys.<BR>The results obtained by Co and Cu additions to Ni-Mn alloys show that the initial and maximum permeabilities of Ni-Mn alloys decrease rapidly with increasing Co content and gradually with increasing Cu content. In the case of Co additions, the alloy consisting of 77.70%Ni, 19.30%Mn and 3.00%Co shows the highest initial permeability of 2250, and the alloy of 81.25%Ni, 11.75%Mn and 7.00%Co exhibits the highest maximum permeability of 7700. In the case of Cu additions, the highest initial permeability of 5750 is obtained on the alloy consisting of 75.88%Ni, 20.30%Mn and 3.82%Cu, and the highest maximum permeability of 17600, on the alloy of 77.28%Ni, 20.95%Mn and 1.77%Cu.
