MECHANICAL AND PHYSICAL PROPERTIES OF INVAR AND INVAR-TYPE ALLOYS

Abstract

This memorandum deals with the mechanical and physical properties of Invar and Invar-type alloys. Most of these are basically iron-nickel alloys which display unusual temperature dependencies of the thermal expansion and/or thermoelastic coefficients. This memorandum describes the compositions and properties of the most useful of these alloys, principally those which exhibit a constant modulus of elasticity or a very low thermal expansion over a significant temperature range. Specific alloys discussed are as follows: Invar, Super Invar, Stainless Invar, Elinvar, Ni-Span alloys, Vibralloy, Iso-Elastic, as well as some experimental alloys.
