Paper Abstract

A new measurement procedure, based on use of a scanning radiometer system and laser heating apparatus, has been applied to evaluate thermal conductivity of a 7075-T651 plate aluminum alloy specimen. This commercially available radiometer system operates on the principle of differential temperature measurement, where the temperature increments are produced by applied stress or heat. It also features digital data processing and display of thermographic images. The thermal conductivity value determined by this procedure was compared with a reference value for the material, and the two agree within the estimated error bounds of the methods.
