Transient thermal conductivity measurements: comparison of destructive and nondestructive techniques
Nancy Mathis
Transient thermal conductivity methods have benefited from the rapid nature of the testing, but at the same time these methods are destructive because a sample must be prepared. Laser flash diffusivity is an example of a well-established transient method of measuring thermal conductivity, which requires samples to be prepared to a diameter of 12.4 mm.
