“…In particular, the introduction of coated hardmetal grades in 1969 strengthened their position, as the corresponding coatings can now be tailored to the respective processing problems (materials, machining conditions), which leads to a significant increase in manufacturing productivity [112][113][114][115][116][117].…”

Hardmetals are tungsten carbide (WC)-based composites, which are made of WC as a hard phase and transition metals such as Co, Fe, or/and Ni as ductile binder matrices. Their properties can be mainly tailored through the grain sizes of the sintered carbides and the amount of metallic binder. As successful tool materials, hardmetals are widely applied in metal cutting, wear applications, chipless forming, stoneworking, wood, and plastic working. In 2017, about two-thirds of tungsten consumption (including recycled materials) were produced for hardmetals in the world. This paper briefly introduces the development of manufacturing technology on WC-Co hardmetals from three aspects: powder preparation, bulk densification, and performance characterization. Two special WC-Co hardmetals are also described: cobalt-enrichment zone (CEZ) hardmetals, and binderless hardmetals. Furthermore, the development prospects for manufacturing techniques of hardmetals are also presented in the end. Keywords Hardmetal • Ultrafine WC powder • Ultrafine cobalt powder • Extrusion press • Liquid sintering • Cobaltenrichment zone hardmetal • Binderless hardmetal 2 Powder preparation techniques Although WC-Co hardmetals can be made directly with mixing and reactive sintering of tungsten, carbon, and cobalt powders [6], the most commonly used method for preparing Tungsten www.springer.com/42864

Turning of hardened AISI 4340 steel is regarded as one of the demanding challenges in machining sectors where precision tolerances are essential for automobile parts. The AISI 4340 steel is broadly utilized in forged steel automotive crankshafts systems, hydraulic forged and additional machine tool purposes because of their improved characteristics. Moreover, one of the keys confronts in the machining of hard 4340 steel is the comparatively deprived machining behavior that reduces the functionality of the material and further leads to component rejection at the final inspection stage. In addition, accelerated tool wear necessitates for repeated changing of cutting tool that results in higher machining and tooling costs. This comprehensive review aimed to present in-depth features on the development of machining performances using various cutting tools. This review focus is to provide a broad perceptive of the role of controllable variables during machining of hardened steel. This review analysis examines the response variables and their advantages of chip morphology and heat generation. The comprehensive overview of machining settings, key machinability indicators and statistical analysis for AISI 4340 steel. This overview will provide academic, industrial and scientific communities with benefits and shortcomings through improved conceptual understanding towards further research and development.

“…The results revealed that the failure mechanism of the uncoated tools was chipping due to the shortage of mechanical strength, while the multilayer-coated carbide tools had a steady wear growth. Ginting et al [8] verified that the coated carbide tools reduced the machined surface roughness because of its high hardness and low friction coefficient.…”

In the present paper, the wear and breakage mechanisms of coated carbide tools are investigated in milling of H13 steel (HRC 30-35) and SKD11 hardened steel (HRC 58-62). The experiment results indicate that the hardness of workpiece has a dominant effect on tool failure patterns. Due to the low hardness of H13 steel, low-stress-repeated impact load on the tool induces the generation of cracks, but not enough to cause tool fracture. Thus, tool failure pattern is flank wear in milling of H13 steel. In contrast, the high-stress-repeated impact load facilitates the initiation and propagation of cracks and ultimately leads to breakage of rake face when milling SKD11 hardened steel. The geometry model of tool wear and breakage is established to explore the variation of tool angle. It is found that the flank wear reduces the clearance angle, while the breakage of rake face decreases the rake angle. In addition, the effect of tool wear and breakage on the cutting forces and chip formation is studied. The flank wear increases the friction coefficient between tool and H13 steel, and the breakage of rake face increases chip deformation and reduces the sharpness of cutting edge, both of which result in the increase in cutting forces. Furthermore, the wave-shaped chips are formed throughout milling of H13 steel, while the breakage of rake face results in the curling and separation of sawtooth chips when milling SKD11 hardened steel.
