A COMPARATIVE STUDY OF FLANK WEAR CHARACTERISTICS WHEN TURNING 20MNCRS5 CASE HARDENING STEEL AND ALLOY 718 SUPERALLOY
Conference contribution, 2018

The present study deals with characterization of flank wear lands of uncoated cemented tungsten carbide (WC-Co) tools used for machining two different material types, a case hardening steel (20MnCrS5) and a heat-resistant superalloy (Alloy 718). Scanning electron microscopy (SEM) and the electron backscatter diffraction (EBSD) technique were used to investigate the flank wear lands after machining the two materials. Differences in surface topographies as well as induced strains from the machining tests are discussed with respect to the underlying tool-loads and resulting wear mechanisms during machining of the two types of materials.
