Abstract
Pulse-heating experiments were performed on the strip specimen, taking the specimen from room temperature to melting point based on rapid resistive self-heating of the specimen. The normal spectral emissivity of the specimen was measured by integrating sphere reflectometry developed at HIT. At the same time, the radiance temperature is measured by high-speed pyrometer from 1100K to melting point. Details of the measurement technique, measurement apparatus and the calibration technique are described. Results of normal spectral emissivity of niobium at 905nm from room temperature to its melting point are presented and discussed.
