Conclusions

  1. 1.

    We recommend strict observance of the technological parameters in all metallurgical operations affecting the final structure of Fe−Ni−Co Elinvars, since the thermoelastic coefficient of these alloys is effected greatly by the chemical composition of austenite and the texture.

     
  2. 2.

    Plastic deformation before tempering promotes high thermal stability of the modulus of elasticity and its weak sensitivity to magnetic field in alloys with cobalt.

     
  3. 3.

    High-temperature Elinvars are recommended for high-precision elastic sensing elements for prolonged operation up to 300° and briefly at higher temperatures.
