: cemented carbide; WC-Ni alloy; microstructure; formation; defect 1 Introduction Cemented carbides are used in many industrial applications including cutting tools, drilling hard rock and wear parts due...] reported that in the immersion corrosion and electrochemical tests, the corrosion resistance of the WC-Ni-Cr cemented carbide under acidic conditions (HNO3, H2SO4, HCl) was significantly superior......
and platelet reinforcement is well known in the field of advanced ceramics with improved toughness[1]. It has been demonstrated that this idea can be applied successfully as well to WC-based cemented carbide. Trigonal or truncated trigonal WC platelets were shown to form in-situ by reaction sintering processes or recrystallization[2-5]. Compared with the conventional platelet-free cemented carbide......

Zheng-yi, LIU Yong. Effect of WC grain size on mechanical properties and microstructures of cemented carbide with medium entropy alloy Co-Ni-Fe binder [J]. Journal of Central South University, 2020... carbides with new (Co-Ni-Fe) binder and traditional cemented carbide, WC-10Co (wt%) (WC-Co) was also prepared under the same conditions. For convenience, WC-CoNiFe samples with different WC particle......
