Abstract

Metallic corrosion is an expensive problem in industrialised countries, creating annual costs that are equivalent to around 3.5% of GDP. More than half of this amount is attributable to atmospheric corrosion. A large amount of scientific and technical literature has been published in the field of atmospheric corrosion, and numerous books and many general treatises have focused on this topic. In the period between 1970-2000 ASTM-STP made great efforts to disseminate progress in this field through the periodic publication of monographies and organisation of symposia on atmospheric corrosion. This special issue of Materials (MDPI) brings together the state of the art in this field, highlighting the advances made in the last fifteen years and identifying the areas where future research will need to concentrate. This publication is intended not only for researchers in the field of atmospheric corrosion, but also for technicians in charge of the design and maintenance of metallic items or concerned with their integrity and duration in the atmosphere.

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

One promising concept for future nuclear reactors uses liquid metals like Pb as reactor coolant. In this work, fretting of fuel clad materials is investigated in Pb environment at relevant operating conditions. A novel test apparatus is presented that allows fretting tests in liquid lead with high accuracy and reproducibility also during long term tests. Tolerable operating conditions concerning fretting wear by evaluating the specific wear coefficient and the concept of fretting maps are given.

Abstract

Ultrafine-grained metallic materials produced by severe plastic deformation methods are at the cutting edge of modern materials science. UFG-metals exhibit outstanding properties which make them very interesting for structural or functional engineering applications. Fifteen articles in this special issue address a broad variety of topics: New developments in severe plastic deformation techniques, advances in modeling and simulation of the severe plastic deformation processes, mechanical properties under monotonic and cyclic loading of homogenous and graded UFG structures, dominating deformation mechanisms in UFG materials, advances and strategies for high conductivity UFG-materials, correlation between severe plastic deformation parameters and resulting materials properties and peculiarities in the corrosion behavior of UFG materials. The book covers latest results on ultrafine-grained titanium, aluminum and copper alloys and on UFG iron and steels and thus provides a deep insight to current research activities in the field of ultrafine-grained metals.

Abstract

Aluminium is the world’s most abundant metal and is the third most common element, comprising 8% of the Earth’s crust. The versatility of aluminium makes it the most widely used metal after steel. By utilising various combinations of their advantageous properties such as strength, lightness, corrosion resistance, recyclability, and formability, aluminium alloys are being employed in an ever-increasing number of applications. In the recent decade, a rapid new development has been made in production of aluminium alloys, and new techniques of casting, forming, welding, and surface modification, have been evolved to improve the structural integrity of aluminium alloys. This Special Issue covers wide scope of recent progress and new developments regarding all aspects of aluminium alloys, including processing, forming, welding, microstructure and mechanical property, creep, fatigue, corrosion and surface behavior, thermodynamics, modeling, and application of different aluminum alloys.

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.

Abstract

This book contains selected contributions on surface modification to improve the properties of solid materials. The surface properties are tailored either by functionalization, etching, or deposition of a thin coating. Functionalization is achieved by a brief treatment with non-equilibrium gaseous plasma containing suitable radicals that interact chemically with the material surface and thus enable the formation of rather stable functional groups. Etching is performed in order to modify the surface morphology. The etching parameters are selected in such a way that a rich morphology of the surfaces is achieved spontaneously on the sub-micrometer scale, without using masks. The combination of adequate surface morphology and functionalization of materials leads to superior surface properties which are particularly beneficial for the desired response upon incubation with biological matter. Alternatively, the materials are coated with a suitable thin film that is useful in various applications from food to aerospace industries.
