Weld cracks are unacceptable defects that can compromise the integrity of welded structures. Weld cracking can lead to structural failures which at best will require remedial action and at worst can lead to loss of life. Weld cracking in ferrous alloys reviews the latest developments in the design, evaluation, prevention and repair of weld cracks.Part one reviews the fundamentals as well as recent advances in the areas of welding technology, design and material selection for preventing weld cracking. Part two analyses weld crack behaviour, evaluation and repair of cracking/cracked weld

This issue comprises an extensive body of selected data, on diffusion in iron-based materials, gleaned from research published in leading journals during the past 70 years. The materials covered range from the almost-pure metal, to high-alloy steels (including metallic glasses) and the data reflect the effect of special conditions (thin films, strain, etc.) upon bulk, surface and pipe diffusion. This publication will constitute an invaluable first port-of-call for anyone looking for a quick guide as to the extent of diffusion which is to be expected to occur during any research project or indu

This book is composed of ten chapters. Based on systematic description of research achievements of the project of ultra-fine grain steels and their engineering applications, new theories of microstructural refinement and the newly developed technologies in production of high strength and high toughness steels are introduced. The book features the integration of materials science with engineering technology. In the scope of theories of the strengthening and toughening of ultra-fine grain steels, the theory of deformation induced ferrite transformation (DIFT) for ferrite-pearlite steels has been put forward. The phenomenon of ultra-fine grain refinement effect by the existing precipitates of nanometer size in the steel produced by using thin slab casting and rolling (TSCR) has been discovered and analyzed. The theory of deformation induced precipitation and medium temperature phase transformation control for bainitic steels has been proposed. The theory of resistance against delayed fracturing of high strength and high toughness alloy structural steels has been established. In the aspect of production technologies, some production technologies for obtaining ultra-fine grains and high strength high toughness of steels are introduced. The chemical metallurgy, solidification technique, and welding technique etc. for ultra-fine grain steels are introduced. In the aspect of engineering applications of ultra-fine grain high strength and high toughness steels, all the trial applications and commercial applications in the areas of civil constructions, automobile manufacturing and engineering machinery etc. are described. The book provides theoretical concepts and engineering application technologies for the research, production, and application of ultra-fine grain steels.

Stainless steels represent a quite interesting material family, both from a scientific and commercial point of view, following to their excellent combination in terms of strength and ductility together with corrosion resistance. Thanks to such properties, stainless steels have been indispensable for the technological progress during the last century and their annual consumption increased faster than other materials. They find application in all these fields requiring good corrosion resistance together with ability to be worked into complex geometries. Despite to their diffusion as a consolidated materials, many research fields are active regarding the possibility to increase stainless steels mechanical properties and corrosion resistance by grain refinement or by alloying by interstitial elements. At the same time innovations are coming from the manufacturing process of such a family of materials, also including the possibility to manufacture them starting from metals powder for 3D printing. The Special Issue scope embraces interdisciplinary work covering physical metallurgy and processes, reporting about experimental and theoretical progress concerning microstructural evolution during processing, microstructure-properties relations, applications including automotive, energy and structural.
