Abstract

Future applications in the field of energy production demand for materials which can withstand high temperatures and neutron-doses. Oxide dispersion strengthened (ODS) steels are candidate materials for these requirements.The present work focuses on the characterization of ferritic ODS steels. The main aspect is the analysis of the crystallographic texture after different thermo-mechanical treatments by modern electron microscopy techniques.

Abstract

The deformation behavior of steels is strongly influenced by their microstructure which is a result of the alloying elements and thermal treatments. In this work, the microstructure and the deformation behavior of a non-alloyed deep drawing DC04 steel was investigated. The microstructure was analyzed during heat treatment by EBSD, then microcompression experiments were performed on selected microstructural units and then bulk steel samples were mechanically tested by tensile experiments.

Abstract

In this Special Issue of Metals, an open access forum is provided for publishing original papers that the covers direct and effective correlations between a wide range of thermomechanical processing routes and generated microstructure, hence, the final physical and mechanical properties of the materials. The following aspects of the science and engineering of various metals and alloys are covered in this book:• Original research studies that relate to the understanding of the properties obtained following specific processing/heat treatment route (Experimental, theoretical, and simulation modeling).• Understanding the mechanisms involved in microstructure evolution and phase transformation during processing of materials, specifically as they relate to the understanding of final mechanical properties.• Nano/micro/macro structure characterization and chemistry of metals/alloys used in automotive, power generation, nuclear, aerospace, and medical applications.• Micro/macro texture devolvement during thermo-mechanical processing of metals/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

The combination of distinct materials is a key issue in modern industry, whereas the driving concept is to design parts with the right material in the right place. In this framework, a great deal of attention is directed towards dissimilar welding and joining technologies. In the automotive sector, for instance, the concept of “tailored blanks”, introduced in the last decade, has further highlighted the necessity to weld dissimilar materials. As far as the aeronautic field is concerned, most structures are built combining very different materials and alloys, in order to match lightweight and structural performance requirements. In this framework, the application of fusion welding techniques, namely, tungsten inert gas or laser welding, is quite challenging due to the difference in physical properties, in particular the melting point, between adjoining materials. On the other hand, solid-state welding methods, such as the friction stir welding as well as linear friction welding processes, have already proved to be capable of manufacturing sound Al-Cu, Al-Ti, Al-SS, and Al-Mg joints, to cite but a few. Recently, promising results have also been obtained using hybrid methods. Considering the novelty of the topic, many relevant issues are still open, and many research groups are continuously publishing valuable results. The aim of this book is to finalize the latest contributions on this topic.
