6. Phase equilibria and thermodynamic properties of high-alloy tool steels : theoretical and experimental approach
Abstract : The recent development of tool steels and high-speed steels has led to a significant increase in alloy additions, such as Co, Cr, Mo, N, V, and W. Knowledge about the phase relations in these multicomponent alloys, that is, the relative stability between different carbides or the solubility of different elements in the carbides and in the matrix phase, is essential for understanding the behaviour of these alloys in heat treatments.

7. Multicomponent diffusional reactions in tool steels : Experiment and Theory
Abstract : Many phenomena determining the microstructure of a tool steel and consequently the properties of the material, are governed by multicomponent diffusion. The diffusion driven reactions that take place during, for example, tempering of a hot-work tool steel or when the microstructure develops during hot isostatic pressing of cold-work tool steel, are dependent on the types and amounts of alloying elements.

9. Microstructure and Properties of Additively Manufactured Tool Steels for Hot Stamping
Abstract : Hot work tool steels are commonly used to produce dies for hot stamping, where the steels are exposed to cyclic thermal and mechanical loads. There is a constant demand to improve the lifetime of the dies. Additive manufacturing (AM) provides new solutions for tool design. READ MORE

10. Chromium martensitic hot-work tool steels : damage, performance and microstructure
Abstract : Chromium martensitic hot-work tool steel (AISI H13) is commonly used as die material in hot forming techniques such as die casting, hot rolling, extrusion and hot forging. They are developed to endure the severe conditions by high mechanical properties attained by a complex microstructure. READ MORE
