“…Due to limited thermal stability, these alloys could be used just as cold-work tool steels. At the beginning of the 21st century, there were also trials in substituting vanadium partially with niobium [ 63 , 64 , 65 , 66 ]. These elements form the same type of carbide (MC), while NbC is harder than VC.…”

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.

“…In the practical production process, the segregation is inevitable so measures are taken such as decreasing or refining the eutectic carbides, increasing nucleation or inhibiting the growth of eutectic carbides. However, methods such as accelerating the cooling rate [15,16], adopting low superheat [17], adding an alloy element [18][19][20][21] or rare earth for modification treatment [22][23][24][25] bring a very limited improvement to the mechanical properties of steel. The addition of alloying elements in high-carbon tool steels is one of the countermeasures in controlling carbides in these steels.…”

Abstract:The effect of titanium on the carbides and mechanical properties of martensitic stainless steel 8Cr13MoV was studied. The results showed that TiCs not only acted as nucleation sites for δ-Fe and eutectic carbides, leading to the refinement of the microstructure, but also inhibited the formation of eutectic carbides M 7 C 3 . The addition of titanium in steel also promoted the transformation of M 7 C 3 -type to M 23 C 6 -type carbides, and consequently more carbides could be dissolved into the matrix during hot processing as demonstrated by the determination of extracted carbides from the steel matrix. Meanwhile, titanium suppressed the precipitation of secondary carbides during annealing. The appropriate amount of titanium addition decreased the size and fraction of primary carbides in the as-cast ingot, and improved the mechanical properties of the annealed steel.
