Abstract
The paper is linked to the investigation of lubricants for massive hot forging It was observed temperature range of 200470°C and screw press was used for tests The research on friction has been done for AlMg and AlCuMgFeNi aluminium alloys In this connection physical and numerical investigation of friction are performed On the basis of the ring upsetting technique the effect of temperature on the friction factor value has been investigated The regressions for the relationship between friction factor and temperature for all lubricants under study have been obtained Moreover the sets of calibration curves were drawn Each set of calibration curves corresponds to the definite type of aluminium alloy as well as definite conditions of deformation Some practical recommendations were given
