Abstract

Accurate description of materials requires the most advanced atomic-scale techniques from both experimental and theoretical areas. In spite of the vast number of available techniques,

however, the experimental study of the atomic-scale properties and phenomena even in

simple solids is rather difficult. In steels the challenges become more complex due to the

interplay between the structural, chemical and magnetic effects. On the other hand,

advanced computational methods based on density functional theory ensure a proper

platform for studying the fundamental properties of steel materials from first-principles. In

1980’s the first-principles description of the thermodynamic properties of elemental iron

was still on the borderline of atomistic simulations. Today the numerous application-
oriented activities at the industrial and academic sectors are paired by a rapidly increasing

scientific interest. This is reflected by the number of publications on ab initio steel research,

which has increased from null to about one thousand within the last two decades. Our

research group has a well established position in developing and applying computational

codes for steel related applications. Using our ab initio tools, we have presented an insight to

the electronic and magnetic structure, and micromechanical properties of austenite and

ferrite stainless steel alloys. In the present contribution, we review the most important

developments within the ab initio quantum mechanics aided steel design with special emphasis

on the role of magnetism on the fundamental properties of alloy steels.

Abstract

Alloy steels play a pivotal role in modern society. Their continued development improves the human condition for everyone on earth. Their broad use has resulted in a wide variety of continuing challenges to address economic, manufacturing, and industrial issues. This book contains twenty-three papers covering a wide cross-section of alloy steels and technical problems. Readers interested in solving current manufacturing and application problems will find this issue helpful. The papers contained within cover a wide range of topics by a broad set of authors from across the globe. There are papers covering structure–property relations on various alloys. Other papers discuss the proper processing of alloy steels through the welding, electroslag remelting, and rolling processes. A significant number of the papers cover optimizing the heat treatment of traditional alloys as well as new alloys. There are papers that concentrate on providing real-world performance data on alloy steels, an important but under-studied topic. Of particular interest is a review on the welding of austenitic and duplex stainless steels that gives neophytes and experienced researchers an excellent introduction to the state-of-the-art. This collection of work should be valuable to anyone interested in alloy steels.

Abstract

This book investigates the tension, fatigue and microstructural properties of micro powder injection molded (µPIM) 17-4PH stainless steel components typically used in micro systems technology. The comparison with conventional produced bulk material showed already comparable mechanical properties but need for microstructural optimization.

Abstract

The papers collected in this special issue clearly reflect the modern research trends in materials science. These fields of specific attention are high-Mn TWIP steels, high-Cr heat resistant steels, aluminum alloys, ultrafine grained materials including those developed by severe plastic deformation, and high-entropy alloys. The major portion of the collected papers is focused on the mechanisms of microstructure evolution and the mechanical properties of metallic materials subjected to various thermo-mechanical, deformation or heat treatments. Another large portion of the studies is aimed on the elaboration of alloying design of advanced steels and alloys. The changes in phase content, transformation and particle precipitation and their effect on the properties are also broadly presented in this collection, including the microstructure/property changes caused by irradiation.
