This work aims to assess the economic benefit of using high strength steel (S460) and/or high performance concrete (C50/60) in composite steel-concrete columns. The use of high performance materials (HS materials) leads in particular to a reduction in the quantity of raw material, with equal loading. This implies the construction of a lighter structure or, while retaining the same section dimensions, structures with greater spans. The complexity of the economic interest assessment lies in the fact that many elements are involved, such as the steel profile, concrete, rebar, stirrups, labor, etc. Consequently, the variation in the quantity of raw material of concrete and steel, being the main factor of the presence or not of an economic benefit, does not fully explain the results. Two studies concerning the study of the economic benefit of high performance steel have already been carried out at the University of Liege: one concerning composite structures and the other concerning steel structures. These studies have in common the fact that they only considered HS steels. Consequently, the objective of this thesis is on the one hand, to integrate HS concrete in an economic study of this kind and on the other hand, to extend research for HS steels. Consequently, the designer can, on the basis of this work, determine if there is an economic benefit in using HS materials for a composite column or not, for a column length and a compression load known.

The Metallurgy of Zinc Coated Steels provides a comprehensive overview of the science and engineering of zinc coatings. Beginning with a look at new innovations made in the hot-dip coating methods (CGL), the book goes on to discuss phase equilibria, Zn bath phenomena and overlay coating formations. Both processing methods and controls are covered, as well as corrosion resistance and coating product properties. The book concludes with a discussion of future opportunities for zinc coatings. This book is a vital resource for both individuals new to this area while also serving as a handbook for users and producers of zinc coatings.

A variety of topics concerning ultrahigh-strength ferrous steels were collected in this book. At present, most of the ferrous steels are applied to cold sheet parts. However, they may be used as the materials of hot-forged parts in the future, because of the excellent performance of the mechanical properties. It is hoped that many researchers will have an interest in the applications of the ferrous steels to the hot-forging parts.

In the special issue related to Modelling the Deformation, Recrystallization and Microstructure-Related Properties in Metals, we presented a wide spectrum of articles dealing with modelling of microstructural aspects involved in deformation and recrystallization as well as simulation of microstructure-based and texture-based properties in various metals. The latest advances in the theoretical interpretation of mesoscopic transformations based on experimental observations were partially discussed in the current special issue. The studies dealing with the modelling of structure-property relationships are likewise analyzed in the present collection of manuscripts. The contributions in the current collection evidently demonstrate that the properties of metallic materials are microstructure dependent and therefore the thermomechanical processing (TMP) of the polycrystalline aggregates should be strictly controlled to guarantee the desired bunch of qualities. Given this, the assessment of microstructure evolution in metallic systems is of extraordinary importance. Since the trial-error approach is a time-consuming and quite expensive methodology, the materials research community tends to employ a wide spectrum of computational approaches to simulate each chain of TMP and tune the processing variables to ensure the necessary microstructural state which will provide desired performance in the final product. Although many hidden facets of various technological processes and related microstructural changes were revealed in the submitted works by employing advanced computational approaches, nevertheless, the contributions collected in this issue clearly show that further efforts are required in the field of modelling to understand the complexity of material’s world. The final goal of modelling efforts might be a development of a comprehensive model, which will be capable of describing many aspects of microstructure evolution during thermomechanical processing.
