“…Furthermore, its more ductile FCC structure also leads to the improvement of cemented carbide fracture toughness. The principal difference between them is the higher stacking fault energy of Ni that results in lower hardening rates [6][7][8][9][10][11][12][13][14][15].…”

“…WC based hard alloys have been used in a wide range of applications including metal cutting tools, mining tools, wear resistant parts and wire-drawing dies [1][2][3][4][5]. Since the invention of WC hard alloys, Co metal has been the most optimum binder phase for producing these kinds of materials due to its good wettability to WC grains and high mechanical properties which bring to the remarkable properties of WC-Co hard alloys such as high hardness and toughness [5][6][7][8].…”

“…Since the invention of WC hard alloys, Co metal has been the most optimum binder phase for producing these kinds of materials due to its good wettability to WC grains and high mechanical properties which bring to the remarkable properties of WC-Co hard alloys such as high hardness and toughness [5][6][7][8]. However, several drawbacks of using Co binder for WC hard alloys have been found such as low corrosion-, oxidation-resistance and the raising the suspects of harmful effects to human body concerning to WC-Co containing dust [3,[7][8][9][10]. Moreover, the high price and limitation of Co resource have to be taken into consideration.…”

“…Moreover, the high price and limitation of Co resource have to be taken into consideration. Recently, efforts have been paid to find out new binder alloys to replace Co in WC hard alloys in which Ni, Fe and their alloys have been considered as the ideal binders for WC hard alloys [2][3][4][5][6][7][10][11]. The substitution of Co by Ni and Fe has been investigated in literature.…”

In this research, WC-7(Ni,Fe) hard alloys were prepared by ball milling, cold compaction and finally consolidated by hot isostatic pressing. The effect of binder composition and sintering temperature were investigated in term of the microstructure, density and mechanical properties of sintered samples. Density of hard alloys was measured by the Archimedes' principle while the microstructure was observed using a scanning electron microscope. The Vickers hardness was investigated at load of 30KG and the fracture toughness was calculated based on the Palmqvist crack method. The results revealed that the density of sintered samples was obtained in the range of 14.65 to 14.8 g/cm3 meanwhile the measured Vicker hardness and fracture toughness were respectively achieved from 1260 to 1520 HV30 and 11,7 to 17,5 MPa.m1/2 depending on the binder composition and sintered temperature.

There is a major interest in replacing cobalt binder in hardmetals (cemented carbides) aiming for materials with similar or even improved properties at a lower price. Nickel is one of the materials most commonly used as a binder alternative to cobalt in these metal-ceramic composites. However, knowledge on mechanical properties and particularly on fatigue behavior of Ni-base cemented carbides is relatively scarce. In this study, the fatigue mechanics and mechanisms of a fine grained WC-Ni grade is assessed. In doing so, fatigue crack growth (FCG) behavior and fatigue limit are This microscopic failure mode is rationalized on the basis of the comparable sizes of the cyclic plastic zone ahead of the crack tip and the characteristic microstructure length scale where fatigue degradation phenomena take place in hardmetals, i.e. the binder mean free path.
