“…Plastic deformation in this phase is characterized by the transition from plastic deformation of base metals (BM) to the deformation in appropriate thin layers immediately next to the friction plane. It is considered that, during this phase, a dynamic heat balance between the extended heat and the heat that is transferred to the BM and the environment is established [3][4][5]. As a consequence of reaching maximum temperature while set at tension condition, the mixed material in the friction plane is found to be in a viscoplastic condition.…”

The paper presents the viscoplastic phenomena observed during the rotational friction-welding process of high-speed steel M2 (AISI SAE) with carbon steel 1060 (AISI SAE). The structure, phase composition and distribution of the carbide phase in the friction plane and adjoining zones are examined by using optical microscopy (OM) with a system for quantitative analysis, and scanning electron microscopy (SEM) in addition to EDS analysis. The experimentally-checked mathematical relationship is suggested for the calculation of the radial movements of the carbide phase, immediately next to the friction plane. On the basis of qualitative and quantitative evaluation of the microstructural and rheological appearances, a model of carbide phase distribution is also established in the viscoplastic and viscous layers in the area of the friction plane.
