THE COEFFICIENT OF LINEAR thermalexpansion (CTE, , or 1) is a material propertythat is indicative of the extent to which a mate-rial expands upon heating. Different substancesexpand by different amounts. Over small tem-perature ranges, the Thermal Expansion of uni-form linear objects is proportional to tempera-ture change. Thermal Expansion finds usefulapplication in bimetallic strips for the construc-tion of thermometers but can generate detrimen-tal internal stress when a structural part is heatedand kept at constant a more detailed discussion of thermalexpansion including theory and the effect ofcrystal symmetry, the reader is referred to theCINDAS Data Series on Material Properties,Volumes 1 to 4, Thermal Expansion of Solids(Ref 1).
THE COEFFICIENT OF LINEAR thermal expansion (CTE, α, or α 1) is a material property that is indicative of the extent to which a mate-rial expands upon heating.
