Sintering temperature optimization of ultra-fine Tungsten Carbide Cobalt (WC-CO) tool insert with addition of Carbon (C) and Vanadium Carbide (VC) \ Muhammad Haikal Muhammad Mukhtar

Production of Tungsten Carbide Cobalt (WC-Co) tool inserts have been the subject of interest for multiple research programmes around the world, with the hope of improving mechanical properties as the result from reducing grain size from sub¬micron level to ultra-fine level. WC-Co tool inserts are ma...
