ON SOME MECHANICAL, MAGNETIC AND MAGNETOELASTIC PROPERTIES OF WIRES MADE OF INVAR ALLOYS

摘要

The influence of thermal treatment a and plastic deformation on the thermal expan- sion of the 36/100wt. Ni-Fe Invar alloy was studied. The dependence of Curie temperature and linear saturation magnetostriction on the Ni concentration in the alloy was plotted for certain Ni-Fe Invar alloys with small additions of Mn and Si. The dependence of relative magnetization on relative temperature and that of he Young modulus on the magnetic field were analyzed for some Ni-Fe alloys and a Ni-Fe-CO Invar alloy.
