Excitation of a temperature wave by a rectangular thermal surface pulse

Journal of engineering physics Aims and scope

Abstract

We calculate the temperature field in a metal under the action of a rectangular thermal surface impulse with a fixed total energy and varying duration. It is shown that for a given duration of this impulse, conditions are created which ensure a maximal shift of the melting isotherm toward the interior of the metal.
