Special Issue Information

This Special Issue was initiated by Professor A.I. Zaitsev.

It is with great regret that we announce that on September 20 2023 A.I. Zaitsev passed away.

Over 40 years of scientific work, he and the scientific team under his leadership experimentally studied the thermodynamic, physico-chemical properties of a large number (>100) of metal and slag systems vital for metallurgical technologies. On the basis of the obtained data and a model of associated solutions, the foundations of a new theory of metallurgical slags and melts of inorganic compounds were created.

During the implementation of numerous projects, dozens of new grades of structural steels of different classes (IF, IFHS, HSLA, TRIP, hot stamped) with improved mechanical and corrosion properties, as well as their production technologies, were developed. Many works were awarded by the Government of the Russian Federation, international, and Russian exhibitions.

We highly appreciate that A.I. Zaitsev was the Editor of Metals, and we hope that this Special Issue will be an expression of our respect and memory of the outstanding scientist.


Dear Colleagues,

High-strength low-carbon microalloyed steels are one of the most commonly used structural materials due to their wide range of applications, including in mechanical engineering, shipbuilding, construction, transport, and many other branches of engineering and industry. Their development is based on the purposeful formation of an optimal structural state that provides the highest and most stable indicators of a complex of technological and service properties, including those that are difficult to combine. In this case, their key role is to control the type, morphology, and dispersion of the microstructure, as well as the characteristics of the present non-metallic inclusions and phase precipitates.

This Special Issue aims to present the latest studies on the formation and evolution patterns of non-metallic inclusions and phase precipitates in low-carbon microalloyed steels, and on the influence of their characteristics (type, quantity, size, morphology, and distribution over the metal volume) on the microstructure and the technological, mechanical, and other service properties of hot- and cold-rolled steel. We will consider papers on experimental studies; the thermodynamic and kinetic modeling of phenomena and transformations that occur during smelting; crystallization; and the temperature-deformation processing of steel. In addition, we welcome review articles on recent advances in research and the application of the purposeful formation of non-metallic inclusions and phase precipitates in low-carbon microalloyed steels.

In microalloyed steels, plastic instabilities often appear which have been found to be associated with changes in the microstructure. In this paper, research was carried out on the influence of the microstructure in different areas of the deformation zone during the formation of Lüders bands in niobium microalloyed steel. Thermography and digital image correlation during static tensile testing were used to research deformation behavior and the area before and during the formation of the Lüders band. Different local values of temperature changes, i.e., stress changes, and strains in the examined areas during the formation of the Lüders band were determined. The highest values of the temperature changes and strains during the formation of the Lüders band were measured in the area of the initial appearance of the Lüders band. In order to clarify the observed changes, a microstructural analysis, using X-ray diffraction, scanning electron and transmission electron microscopy methods, was used. It was established that the observed temperature, i.e., stress, and strain changes are related to changes in the microstructure. The analyses of changes in the microstructure, arrangement and interaction of dislocations with precipitates revealed significant changes in the movement of dislocations and their interaction with fine niobium-containing precipitates during the formation of Lüders bands. The influence of microstructural parameters on the Lüders band formation in niobium microalloyed steel has been established based on this research. Full article
