Temperature dependences of the magnetic and elastic properties were studied on 37% Ni-Fe Inver alloy by means of the optical lever method, the usual ballistic method and the static bending method.　The curves of the saturation magnetization and the magnetization at which the maginetostriction begins to appear display similar profiles plotted against the temperature, the details of these curves however do not coincide each other.　The maximum of magnetic susceptibility, χ_, and Young's modulus, E, change adherently at the temperature accompanied with the phase transformati0ns. χ_ gives an increasing curve whereas E a decreasing one with a plateau in the range of low temperatures.　The saturation magnetostriction displays a gently decreasing curve as the temperature rizes with a minimum at about 400℃ and two maxima at about 250 and 600 ℃.　The volume magnetostriction decreases exponentially except that in the temperature range between 350 and 700℃, in which it dispiays Λ type curve with a maximium at about 550℃.　The magnetoelastic energies, λ^2_sE and ω^2E, derived from Young's modulus, the saturation magnetostriction and the volume magnetostriction show temperature dependences similar to the saturation magnetostriction and the volume magnetostriction them-selves, respectively.
