WebThermal Expansion. If the temperature increases, then the volume of the material also increases. Generally, this is known as thermal expansion.We can express it in this way that it is the fractional change in length or volume per unit change in temperature. In case of expansion of a solid, normally linear expansion coefficient is usually employed. WebFor Kanthal APMT, C06M, C35M, and C36M, the FeCrAl handbook (Field et al., 2024) provides a correlation for the instantaneous thermal expansion coefficient. This correlation is given by: (1) where is the instantaneous thermal expansion coefficient , , , and are fitting constants, and is the temperature in K.
