Abstract:
A new experimental method is proposed for determining the effective absorptivity of a metal under pulsed laser radiation. The method is based on solving an axisymmetric boundary-value heat-conduction problem for a half-space with the use of metallographically measured sizes of the polymorphic-transformation zone in the irradiated material. The method is tested on single-crystal cobalt and St.45 steel samples.
Keywords:
laser, temperature, absorptivity, metal hardening.
