Mathematical model of thermal processes in metals during pulse processing with concentrated energy fluxes

Abstract

The paper considers mathematical modeling of thermal processes in metals during pulsed processing by concentrated energy flows. Calculations of thermal processes in steels under pulsed heating are given, considering the phase transformations and the temperature dependences of the thermophysical properties, as well as the space-time characteristics of the thermal energy source. It is shown that the created mathematical model is universal for various sources of thermal energy and adequately describes the space-time distribution of temperature fields during pulsed heating of the surface layers of metals and alloys.
