The contribution of microstructure and friction in broaching Ferrite–Pearlite steels ARRIETA, Iñaki Mirena ARRAZOLA, PEDRO JOSE Courbon, Cédric Cabanettes, F. Rech, Joël cutting Micro structure Friction chip Ferrite-Pearlite (FP) steels are used in many automotive components. However, their machinability in low cutting speed processes appears to be highly dependent on their metallurgical state. An experimental approach combining broaching and tribological tests under machining-like conditions was developed to determine the key FP features driving machining performance. Fundamental tests were performed on fifteen variants so as to cover a wide range of microstructural properties under dry and lubricated conditions using both uncoated and TiN coated High Speed Steel (HSS) tools. The correlation between the microstructure, tri-bology and outputs such as machining forces and chip thickness ratio is presented. 2020-09-10T09:30:35Z 2020-09-10T09:30:35Z 2020 http://purl.org/coar/resource_type/c_6501 0007-8506 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=158164 https://hdl.handle.net/20.500.11984/1817 eng © 2020 CIRP Elsevier Ltd.
