Abstract:

The properties of some low expansion alloys were studied with the purpose of determining their suitability for main steam lines aboard ship. Alloys of iron-nickel and iron-nickel-cobalt were prepared and their thermal expansion, physical properties and corrosion resistance were studied. In some alloys a material reduction in expansion could be obtained by heat treatment. However, heating to high temperature destroyed the low expansion properties. An alloy containing Fe-54, Ni-28, and Co-18 has an excellent combination of low expansion, low modulus and high elastic limit. This alloy had an average expansion one-fourth that of carbon molybdenum steel between 70 and 800 deg F.
