Download or read book Modeling Steel Deformation in the Semi Solid State written by Marcin Hojny and published by Springer. This book was released on 2017-09-07 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a unique approach to integrated high-temperature process modelling, intended to serve as a design aid for new metal processing technologies. The second edition has been substantially expanded to include new content such as: a new algorithm and test results of 3D stereoscopic visualization; new programming procedures for modelling; the validation of computer simulation using experimental results; a multiscale model of grain growth; a conceptual methodology developing “high-temperature” CCT (continuous cooling transformation) diagrams, and many more examples validating the numerical simulations. The models presented are applied in comprehensive tests in order to solve problems related to the high-temperature deformation of steel. The testing methods include both physical tests using specialist laboratory instruments, and advanced mathematical modelling: the Finite Element method (FE), Smoothed Particle Hydrodynamics method (SPH) and Mo nte Carlo method (MC).This approach, which integrates the fields of physical and computer-based simulations, forms the basis for the described concept of integrated high-temperature process modelling, presented in detail in this book.

Download or read book Effect of Plastic Deformation on Subsequent Decomposition in Aluminum Alloys Al Si and Al Mg Si written by Nikolaĭ Nikolaevich Buĭnov and published by . This book was released on 1953 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of plastic deformation on subsequent decomposition in the alloys Al-Si (1.2 percent Si) and Al-Mg-Si (1.4 percent Mg2Si) was studied with an electron microscope. These alloys were chosen because the first is easily quenched and does not age at room temperature and because in the second no decomposition after quenching and natural aging is detected with the electron microscope (although the properties change). These alloys were chosen also because they could be studied by the oxide-film method. This method was used to study the surface of the samples, which was etched before deformation and aging. It is then possible to observe simultaneously, on the electron photographs, precipitation, the block structure, and those alterations (slip lines, bending of blocks, cracks, etc.) in the submicroscopic structure of the alloys which are caused by deformation.

This book was released on 2016-09-30 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 14th S2P International Conference (October 23 27, 2016, Salt Lake City, USA) was dedicated to the science and processing technologies of the semi-solid metal alloys and composites. Since the discovery of the specific flow behavior of metals in semi-solid state during the early seventies, this fascinating technology has experienced a dynamic and turbulent development history which has led to a whole family of new production processes, new equipments and industrial applications for goals of full use of the technical and economic potential of the flow behaviour, improved materials and process modelling as well as control of processes. All S2P International Conferences have contributed to achieve this goal by providing a forum for scientists to share the common knowledge and to develop a common sense on fundamental topics and industrial requirements.

Available in PDF, EPUB and Kindle. Book excerpt: The occurrence of hot tearing during solidification is one of the major factors influencing both the quality and productivity of aluminum castings. In order to reduce the formation of hot tears, quantitative information regarding both hot tearing formation and semi-solid deformation is essential. In this study, the mechanisms of hot tearing and semi-solid deformation have been investigated via two novel techniques: x-ray micro-tomography on material deformed in the semi-solid region, and development of a three phase microstructural model based on a geometry derived from a Voronoi diagram with rounded corners and porosity. Numerical techniques were utilized to quantify both the size evolution and orientation of internal damage relative to void growth. In order to conduct the above research, a new semi-solid tensile deformation methodology was devised which uses a two thermocouple control technique to enable accurate measurement of semi-solid tensile strength and ductility. The experimental work was conducted on the aluminum - magnesium alloy AA5182 in the as-cast and hot isostatic pressing (HIP) states. The x-ray micro-tomography technique was used to observe that semi-solid deformation is accommodated by internal damage via growth of as-cast porosity and the nucleation of new damage-based voids. As the volume fraction of damage increases, the growth of voids occurs in an orientation perpendicular to the loading direction, both through expansion within the grain boundary liquid and via coalescence between voids. The damage then localizes, causing failure. The finite element semi-solid microstructural model was used to explore the effects of fraction solid, fraction porosity, and grain size on semi-solid constitutive behaviour. The simulations revealed that increased grain size and fraction porosity lead to a reduction in flow stress for a given fraction solid. Furthermore, local strain accumulation was linked to hot tearing, since strain localizes in the liquid very.

Available in PDF, EPUB and Kindle. Book excerpt: The major issue of energy saving and conservation of the environment in the world is being emphasized to us to concentrate on lightweight materials in which aluminium alloys are contributing more in applications in the twenty-first century. Aluminium and its related materials possess lighter weight, considerable strength, more corrosion resistance and ductility. Especially from the past one decade, the use of aluminium alloys is increasing in construction field, transportation industries, packaging purposes, automotive, defence, aircraft and electrical sectors. Around 85% is being used in the form of wrought products, which replace the use of cast iron. Further, the major features of aluminium alloy are recyclability and its abundant availability in the world. In general, aluminium and its related materials are being processed via casting, drawing, forging, rolling, extrusion, welding, powder metallurgy process, etc. To improve the physical and mechanical properties, scientists are doing more research and adding some second-phase particles in to it called composites in addition to heat treatment. Therefore, to explore more in this field, the present book has been aimed and focused to bridge all scientists who are working in this field. The main objective of the present book is to focus on aluminium, its alloys and its composites, which include, but are not limited to, the various processing routes and characterization techniques in both macro- and nano-levels.

Download or read book Microstructure Slip Distribution and Strain Hardening in Aluminum Alloys written by RE. Sanders and published by . This book was released on 1982 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: A microstructural approach has been used to explain the deformation characteristics which influence the formability of aluminum alloy sheet materials. Optical metallography and transmission electron microscopy were used to study the response of various aluminum alloys to uniaxial and biaxial deformation. The predominant strengthening mechanisms for a given alloy had the strongest effect on strain localization and biaxial strain hardening behavior. Dispersion-strengthened alloys displayed a wavy slip mode, and high levels of strain hardening and resistance to strain localization. Precipitation or solid-solution-strengthened alloys exhibited more localized deformation and lower capacities for biaxial strain hardening.
