One of the mysteries of the English language finally explained.
The amount a material expands or contracts per unit length due to a one-degree change in temperature.
- ‘The comparatively high thermal expansivity of aluminium leads to looseness unless the steel has a similar coefficient of expansion.’
- ‘The local compression created by the electric field can be related to the expansivity modulus, K, by this expression.’
- ‘They provide resistance to frictional wear, corrosion resistance, nonmagnetic characteristics and, in some alloys, low thermal expansivity at ambient temperatures.’
