چکیده
The microstructure and wear behavior of S390 high-speed steel (HSS) reinforced with different volume fractions MC-type carbides produced via spark plasma sintering were investigated using scanning electron microscopy (SEM) transmission (TEM) in this study. SEM TEM results show that V-W-rich are formed around the added carbides, these have a similar composition to M(C, N) precipitated at high temperatures according thermodynamic calculations. Both macrohardness three-point bending carbide type is dominant factor increasing hardness, fraction leading decrease strength. mechanism HSS metal matrix composites (MMCs) confirmed as abrasive oxidative tracks oxidation films. Compared sample without reinforcement (85 HRA, coefficient 1.50 × 10−15 m2/N), best MT-3 exhibits hardness increase 1.8 HRA three-fold resistance.

Effect of SiC nanoparticles addition on mechanical properties and wear resistance of cemented carbides fabricated by spark plasma sintering
WC-10Co cemented carbides containing 1 to 4 wt% SiC nanoparticles were prepared by spark plasma sintering. The effects of SiC content on microstructure, mechanical properties and wear resistance of the sintered materials were studied. Microstructural studies showed that SiC addition resulted in WC grain coarsening. In addition, the hardness decreased with increasing SiC content. However, the fr...
