“…High-alloy tool steels are multicomponent systems commonly including d-metals in group VI of the Periodic Table. These doping additions in steels lead to the formation of numerous binary and more complex stable or metastable metallide, carbide, and carbointermetallide phases [1][2][3][4][5][6]. Various intermediate phases present in commercial alloys promote excellent mechanical properties depending on the method of production and thermal treatment.…”

Evolution of the phase composition of Fe-Mo-C spinning alloys is investigated in situ with hightemperature x-ray diffraction from room temperature to solidus. The temperature range over which the metastable β-Mn-like phase exists is determined. It is shown that the γ-Fe-based fcc-phase and Mo 2 C-based solid solution coexist in equilibrium at 1273 K and the γ-phase and η-carbointermetallide of W 3 Fe 3 C type coexist with the liquid phase at 1473 K. The vertical section at 11 at.% carbon is plotted.

This article delves into the multifaceted field of managing economic systems amid ongoing waves of social and technological transformation, highlighting the need for adaptive and innovative management strategies to navigate the complexities created by the evolution of societal structures, technological progress, and global interconnectedness. As society moved toward more interconnected and knowledge-oriented paradigms, the traditional boundaries of economic systems were redefined. The integration of new technologies such as artificial intelligence, blockchain and renewable energy solutions requires a strategic re-evaluation of production, consumption and distribution models. Moreover, changing expectations for a digitally enabled workforce and greater emphasis on sustainable practices are forcing economic systems to adopt flexible management approaches that balance profit motives with social and environmental responsibility.

“…The high hardness, wear resistance, and high-temperature strength of these steels is greatly promoted by alloying with d metals, including those from group 6 of the Periodic Table. The associated solution hardening of the matrix, stabilization of metastable phases of the Fe-C (Fe 3 C and related (Fe, Mo) 34 C 10 ) [1-3], Fe-Mo-C [4], FeCr-C [5], Fe-W-C [6], and Fe-Mo-Cr [7] systems, and, above all, the formation of stable binary, ternary, and more complex intermetallides, carbides, carbon metallides, and solid solutions on their basis [1][2][3][4][5][6][7][8][9], and numerous phase transformations depending on composition and treatment (thermal or mechanical) ensure the excellent mechanical properties of high iron-based alloys on the one hand and the potential for their control on the other.…”
