The linear coefficient of thermal expansion, Young’s modulus and its mean temperature coefficient, and the density have been measured so as to investigate the effect of addition of Mn, Ti or Zn on the Elinvar property of nickel at high temperature. The results show that in the alloy ststems, Ni-Mn, Ni-Ti and Ni-Zn, the Elinvar property of nickel falls down gradually along the magnetic transformation point with increasing addition of each element and also a minimum linear coefficient of thermal expansion, the so-called Invar property, appears near the composition at which the Elinvar property is revealed
