In the case of a pre-hardened steel of the SCM440 series, = 11.5 x 10-6mm/mm, l0 is the initial length of the core pin (mm), l0= 30.52 mm, t is the initial temperature (°C), t = 20°C, and t0 is the temperature after heating (°C), t0= 150°C. COEFFICIENT OF THERMAL EXPANSION FOR VARIOUS The coefficient of thermal expansion is used to determine the rate at which a material expands as a function of temperature. CTE is used for design purposes to determine if failure by thermal stress may occur. Understanding the relative expansion/contraction characteristics of materials is important for application success.

Feb 11, 2019 · The radial coefficients of thermal expansion of ten specimens of Norway spruce were measured at 7.0% and 11.4% MC. No statistically significant differences were found between the two data sets, indicating a negligible effect of moisture content on wood thermal expansion at MC values typical of indoor environments. What is the Coefficient of Thermal Expansion? - MatmatchThe coefficient of thermal expansion (CTE) refers to the rate at which a material expands with increase in temperature. More specifically, this coefficient is determined at constant pressure and without a phase change, i.e. the material is expected to still be in its solid or fluid form.. Different materials have different CTEs, which make them suited for the particular use they are selected for.
