The laser flash method (LFA) is a technique used to measure thermal diffusivity,...

Thermal diffusivity is an important property used to assess how a material transfers heat and reacts to changes in temperature. Thermal diffusivity, alpha, is the ratio of how much heat is conducted in a material relative to how much heat is stored. Similarly thermal conductivity, kappa, describes how much heat is transferred through a material ...
