A novel laser flash method for measuring thermal diffusivity of molten metals
Source abstract
Abstract
Abstract A novel laser flash method has been developed to measure the thermal diffusivity value of molten metals at 700–1800 K. The upper surface of molten metal is instantaneously irradiated by a Nd glass laser. Then, the temperature response of the same (upper) surface is measured by using an InSb infrared detector. The thermal diffusivity value can be estimated from the measured temperature response. This new laser flash method was applied to molten tin, copper and Inconel 601 at high temperature and its validity and usefulness was confirmed by showing good agreement with the values obtained by an ordinary laser flash method and with the reference values as well.
