Book Synopsis Solidification by : Alicia Esther Ares
Download or read book Solidification written by Alicia Esther Ares and published by BoD – Books on Demand. This book was released on 2018-03-14 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost all processing of technologically important materials includes a process where liquid material is cooled to form a solid, called "solidification." In order to form a solid from an undercooled melt, the formation of crystalline nuclei and growth of these nuclei to form a solid are necessary. The process of an atom jumping from the liquid to the solid is a diffusive jump with a driving force. The book Solidification is logically developed through a careful presentation of the relevant theories and models of solidification occurring in a variety of materials. Mathematicians, chemists, physicists, and engineers concerned with melting/freezing phenomena will also find this book to be valuable.

Download or read book Optimizing the Heat Treatment of High Strength Al-Si-Mg and Al-Cu-Mg-Zn written by Ibrahim Mohamed Fawzy and published by LAP Lambert Academic Publishing. This book was released on 2015-10-30 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of aeronautical alloys requires the use of these particular alloys for their strength and ductility. These properties can be further enhanced by controlling the added alloying elements as well as the heat treatment parameters. The objective of the present work was to determine the effect of the interactions between element additions and heat treatment on the alloy microstructure and mechanical properties. The present study was carried out to investigate both the formability and mechanical properties of 6xxx alloy series. The slabs (7 x 11 x 1.5 cm each) were machined and homogenized for 10 h at 520 C, followed by air cooling. The results show that a -iron phase displays low formability and hinders deformation of the grains during cold rolling and leads to premature cracking. The cold rolled structure contains elongated grains with broken -Al5FeSi platelet fragments. In the Mn-containing alloy, the -iron phase is more easily deformable while addition of Sr does not improve the alloy behavior. With beryllium additions, the iron intermetallics precipitate in the form of small, globular -Al8Fe2SiBe script particles, in the interdendritic regions."

Book Synopsis Optimisation of the Heat Treatment Cycles of CSIR Semi-solid Metal Processed Al-7Si-Mg Alloys A356/7 by : Heinrich Moller

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional casting alloys Al-7Si-Mg A356/7 contain between 6.5 and 7.5% Si, together with 0.25-0.7% Mg and are used for critical castings in the automotive and aerospace industries. These alloys are also the most popular alloys used for semi-solid metal (SSM) forming due to good castability and fluidity imparted by the large volumes of the Al-Si eutectic. Despite their industrial importance, there is a lack of detailed research work revealing precipitate micro- and nanostructural evolution during aging of these alloys compared with the Al-Mg-Si 6000 series wrought alloys. This study characterises the heat treatment response of SSM-processed Al-7Si-Mg alloys in comparison with conventionally liquid cast alloys (investment casting and gravity die casting). It is shown that, provided that the maximum quantity of the alloy's Mg is placed into solid solution during solution treatment, and that the alloy's Fe content is within specification, the response to age hardening of Al-7Si-Mg alloys is independent of the processing technique used. The nanostructural evolution of Al- 7Si-Mg alloys after artificial aging with and without natural pre-aging has been characterized using transmission electron microscopy and atom probe tomography and correlated with hardness and mechanical tensile properties. The number densities and Mg:Si ratios of solute clusters, GP zones and ;?-needles were determined. The heat treatment response of SSM-processed casting alloys A356/7 alloys are also compared with SSM-processed Al-Mg-Si 6000 series wrought alloys, with the advantage of having similar globular microstructures. The high Si-content of the casting alloys compared to the wrought alloys offers several advantages, including a faster artificial aging response (shorter T6 aging cycles), higher strength for comparable Mg contents and less sensitivity to prior natural aging on peak strength. Finally, an age-hardening model was developed for the Al-7Si-Mg alloys, including a method of incorporating the effects of changes in Mg-content on the aging curves.
Book Synopsis Comprehensive Materials Finishing by : M.S.J. Hashmi
Download or read book Comprehensive Materials Finishing written by M.S.J. Hashmi and published by Elsevier. This book was released on 2016-08-29 with total page 1467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finish Manufacturing Processes are those final stage processing techniques which are deployed to bring a product to readiness for marketing and putting in service. Over recent decades a number of finish manufacturing processes have been newly developed by researchers and technologists. Many of these developments have been reported and illustrated in existing literature in a piecemeal manner or in relation only to specific applications. For the first time, Comprehensive Materials Finishing, Three Volume Set integrates a wide body of this knowledge and understanding into a single, comprehensive work. Containing a mixture of review articles, case studies and research findings resulting from R & D activities in industrial and academic domains, this reference work focuses on how some finish manufacturing processes are advantageous for a broad range of technologies. These include applicability, energy and technological costs as well as practicability of implementation. The work covers a wide range of materials such as ferrous, non-ferrous and polymeric materials. There are three main distinct types of finishing processes: Surface Treatment by which the properties of the material are modified without generally changing the physical dimensions of the surface; Finish Machining Processes by which a small layer of material is removed from the surface by various machining processes to render improved surface characteristics; and Surface Coating Processes by which the surface properties are improved by adding fine layer(s) of materials with superior surface characteristics. Each of these primary finishing processes is presented in its own volume for ease of use, making Comprehensive Materials Finishing an essential reference source for researchers and professionals at all career stages in academia and industry. Provides an interdisciplinary focus, allowing readers to become familiar with the broad range of uses for materials finishing Brings together all known research in materials finishing in a single reference for the first time Includes case studies that illustrate theory and show how it is applied in practice

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study focused on the tensile properties at ambient and high temperatures of alloy 354 without and with the addition of zirconium. Tensile tests were performed on alloy samples submitted to various aging treatments, with the aim of understanding the effects of the addition made on the tensile properties of the alloy. Zirconium reacts only with Ti, Si, and Al in the alloys examined to form the phases (Al,Si)2(Zr,Ti) and (Al,Si)3(Zr,Ti). Testing at 25°C reveals that the minimum and maximum quality index values, 259 and 459 MPa, are observed for the as-cast and solution heat-treated conditions, respectively. The yield strength shows a maximum of 345 MPa and a minimum of 80 MPa within the whole range of aging treatments applied. The ultimate tensile and yield strength values obtained at room temperature for T5-treated samples stabilized at 250°C for 200 h are comparable to those of T6-treated samples stabilized under the same conditions, and higher in the case of elevated-temperature (250°C) tensile testing. Coarsening of the strengthening precipitates following such prolonged exposure at 250°C led to noticeable reduction in the strength values, particularly the yield strength, and a remarkable increase in the ductility values.

Book Synopsis Influence of the Microstructure on the Thermal Conductivity of Cast Al-Si-Cu-Mg Alloys by : Raimon Parés Viader
Download or read book Influence of the Microstructure on the Thermal Conductivity of Cast Al-Si-Cu-Mg Alloys written by Raimon Parés Viader and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pure aluminium has a high thermal conductivity, but as alloying elements are added the thermal conductivity decreases. How much it occurs depends on the alloying elements and whether they are present in solid solution, as small precipitates or larger particles. The present work studies the influence of Cu and Mg additions on the thermal conductivity of Sr-modified as-cast and T6-heat treated Al-Si alloys for a wide range of temperatures (30-400 oC). An unmodified Al-Si alloy with no additions was analysed as well so as to investigate the influence of the modification with Sr. Three properties were determined to calculate the thermal conductivity: thermal diffusivity, specific heat and density. Thermal diffusivity measurements were carried out by means of a Laser Flash device. Regarding the Sr-modified Al-Si alloys, the highest thermal conductivity corresponds to the alloy without the addition of other elements in both as-cast and T6 condition. The alloys containing Cu have in general a lower thermal conductivity than the alloys with solely Mg. The presence of Mg has an overall beneficial effect in as-cast conditions for an alloy containing Cu. In contrast, this addition becomes detrimental for a copper-bearing heat-treated alloy in most of the temperature range. With regard to the Sr-modification outcome, it was found that enhances thermal conductivity in as-cast alloys. Nevertheless, its influence after the heat treatment requires a further study. The thermal conductivity increases normally with the temperature and when the T6 heat treatment is applied. This increment is attributable to the purer aluminium matrix obtained as the precipitates form, grow and coarsen.
