This reprint contains 14 articles published in the Special Issue, "Use of Modern Materials in Technological Processes Accompanied by Frictional Heating". These articles can be divided into five groups:
1) Analytical modeling of the frictional heating process in systems made of homogeneous and functionally gradient materials (FGMs) 1-7];
2) Numerical simulations of the temperature mode of railway brake systems 8, 9];
3) Experimental studies and numerical simulations of the influence of various types of additives added to the friction material in the wet clutch disc 10, 11];
4) Inverse thermal problems of friction 12];
5) The influence of friction on the stress distribution in a composite containing thin elastic homogeneous inclusions, or that made of FGM 13, 14].
