Inclusion engineering in Co-based duplex entropic alloys

Co-based duplex entropic alloy is designed very recently to replace pure Co as a major component of the binder phase for cemented carbide cutting tools. This work aims to provide a fundamental study of oxide inclusion characteristics in the duplex fcc + hcp Co-based entropic alloys. It is found that the Co85−xCrxFe7.5Ni7.5 (x = 15, 30 at.%) alloys hold the highest liquidus (Tliq) and solidus (Tsol) temperatures, compare with the...
