“…This can be explained by the fact that metastable and stable phases (cementite and graphite) both occur in the microstructure and the calphad method uses the global minimization of the Gibbs' energy for the calculations.

Indefinite-chill materials are used as shell materials for cast work rolls for surface-critical applications in hot rolling mills. Besides a smooth surface quality, a low sticking tendency and low sensitivity against incidents in the rolling mill, the work rolls need the highest wear resistance possible. The microstructure of the indefinite-chill material consists of various carbides (cementite up to 40 area-%) and up to 5 area-% of graphite embedded in tempered martensite. To increase the wear resistance of this material group, the comparably soft cementite has to be replaced by more wear resistant carbides such as MC, M2C or M6C. This can be achieved by increasing the amount of carbide forming elements such as Nb, V, Mo, W or Cr. Nevertheless it is important to maintain a certain amount of graphite in the microstructure to avoid sticking to the rolled material and to lower the sensitivity against mill incidents. It is well known that high amounts of carbide forming elements limit the graphite precipitation and therefore a sophisticated alloying concept is required for this material type. Not only the effects of matrix elements such as Si, Mn, Ni and Co but also the effects of Cr, Mo, W, Nb and V were studied in an intensive research project. This work gives an insight in the results of the project based on the example of the effects of Si and Cr on the phase amounts and the composition of the cementite phase.

The main focus of this article is to explain the scientific and engineering principles behind the development of seismic steel, which is specifically engineered to withstand seismic forces during earthquakes. Through careful control of the steelmaking process, including alloy chemistry and thermomechanical treatments, microstructures are created that provide the necessary strength, ductility, and toughness for seismic applications. S700 steel, also known as ultra-high-strength steel (UHSS), is an advanced material that has gained significant interest in recent years due to its exceptional mechanical properties. It is an example of seismic steel. This review aims to provide an overview of S700 steel, including its composition, characteristics, applications, recent advancements in the field, and potential benefits and challenges associated with using this material. The simulations using JMatPro have shown promising findings, concerning the potential for the studied modified S700 steel alloy to enhance structures' safety and resilience in earthquake-prone regions, as well as the combination of S700 steel and JMatPro represents a significant advancement in materials science and engineering.
