Calculation of temperature field of moving sources of heat taking account for coefficient temperature dependence

Given are the results of numerical investigation of nonstationary temperature fields in metals of moving energy sources when the thermal conductivity coefficient and material heat capacity change with temperature. Calculations are carried out for a number of metals (including molybdenum, as well as Kh18N9V steel), heating has been realized by a single and several parallel and consequent sources. At the same time the values of nonstationary temperatures are calculated on the basis of the linear model at average integral values of the thermal physical coefficients. The discrepancies of the calculation results obtained on the basis of the linear and nonlinear solutions are given
