Measuring the Temperature of Substances upon Fast Heating with a Current Pulse

Аннотация

Features of measuring the temperature of conducting materials (metals, carbide, graphite) with a brightness pyrometer upon heating with a microsecond pulse of electric current are considered. Problems of pyrometer calibration and developing a blackbody model for measuring true temperatures in solid and liquid phases are examined. Estimates of temperature field nonuniformity over a sample and errors of temperature measurement are given.
