随着温度的上升,FeCrAl的晶格常数由于分子的热运动的加剧而增加,根据其与温度的关系推导了热膨胀系数随温度的变化关系。
As the temperature rises, the lattice constant of FeCrAl increases due to the intensification of the thermal motion of the molecule, and the relationship between the thermal expansion coefficient and temperature is deduced based on its relationship with temperature.
