“…One of the most important compounds is the tungsten carbides: hexagonal and cubic mono-carbides WC, and four polymorphs (˛,ˇ, , ε) of semi-carbide W 2 C. The properties of thermal stability and high elastic modulus determine the usage of W-C compounds in the production of wear resistant hard alloys, which form the basis of the metal cutting instruments, for example, the cemented carbide [1][2][3][4] and high-speed steel [5][6][7].…”

“…Based on this further refinement, the transient phase fractions and dislocation densities during a complex thermal regime can be obtained [54]. In addition, precipitation of, e.g., secondary hardening carbides [55] or intermetallic phases can be monitored directly or indirectly by in situ X-ray diffraction [56]. Recently, it has been shown that even processes yielding low signal-to-noise ratio diffraction patterns can be analyzed by a parameter refinement with a global optimizer using a Bayesian approach with a Markov Chain Monte Carlo algorithm instead of the standard Levenberg-Marquardt local optimization technique [57].…”

The Critical Raw Materials (CRMs) list has been defined based on economic importance and supply risk by the European Commission. This review paper describes two issues regarding critical raw materials: the possibilities of their substitution in iron-based alloys and the use of iron-based alloys instead of other materials in order to save CRMs. This review covers strategies for saving chromium in stainless steel, substitution or lowering the amounts of carbide-forming elements (especially tungsten and vanadium) in tool steel and alternative iron-based CRM-free and low-CRM materials: austempered ductile cast iron, high-temperature alloys based on intermetallics of iron and sintered diamond tools with an iron-containing low-cobalt binder.

“…To improve toughness of the alloy, powder metallurgy (PM) technique is applied. PM is effective for the fine and uniform distribution of the carbides [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”

1.2C–4Cr–4Mo–10W–3.5V–10Co–Fe high-speed steel (JIS SKH57; ISO HS10-4-3-10) is often manufactured via casting and forging. By applying powder metallurgy, the properties of the abovementioned material can be improved. In this study, the effects of sintering conditions on the formation of precipitates and pores are evaluated. Additionally, strength with and without hydrostatic pressure during sintering is evaluated via static bending and impact tests. Sintering via hot isostatic pressing (HIP) at 1463 K can effectively eliminate pores and prevent the coarsening of precipitates. Toughness and strength improved by 50% by applying HIP.
