COMPARISON OF PARAMETERS OF SURFACE INTEGRITY OF MACHINED DUPLEX AND AUSTENITE STAINLESS STEELS IN RELATION TO TOOL GEOMETRY
Autor: Čapek, Jiří; Pitrmuc, Zdeněk; Kolařík, Kamil; Beránek, Libor; Ganev, Nikolaj
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)The goal of this contribution was to describe parameters of surface integrity of two machined materials; austenite and duplex stainless steel. Residual stresses and presence of straininduced martensite were studied as a ... -
