Download or read book Eutectic Solidification Processing written by Roy Elliott and published by Elsevier. This book was released on 2013-10-22 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutectic Solidification Processing: Crystalline and Glassy Alloys deals with solidification theory and its application to eutectic processing of crystalline and glassy alloys. The underlying theme is an analysis of the different paths taken by the liquid-solid transformation as the cooling rate increases and a description of the structure and properties of the solid formed, ranging from equilibrium to metastable phase formation in castings, to metallic glass formation in splat quenched ribbons. This text has seven chapters; the first of which describes the main characteristics of the liquid-solid transformation. The chapters that follow show how control over composition, trace impurities, heat flow and cooling rate, and nucleation and growth gives rise to a wide range of solidification structures. Models of the nucleation and growth of eutectic and primary phases are analyzed and used to explain how cast microstructures are formed. Aluminum casting alloys and all types of cast iron are discussed, along with primary phase formation, the dependence of the extent of segregation on solidification conditions, and the practice of segregation prevention during solidification. This book also describes the importance of fluid flow in producing macroscopic segregation in large ingots and considers ways of minimizing this defect. Finally, this book gives a brief account of the various types of metallic glasses, their fabrication, important properties, and potential applications. This book will be of interest to materials scientists and industrial materials engineers.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to study the formation of the solidification structure including the columnar-toequiaxedtransition (e.g., CET) under the influence of ultrasound, a 2-zone furnace system and an ultrasonic equipment were built and utilized. The 2-zone furnace system consists of an induction furnace with a top coil and a bottom coil, a graphite crucible, and. a water-cooled chill block located at the bottom of the crucible. By controlling both the top and bottom coil output power independently, the furnace can create various temperature gradients and cooling rates in different regions of the graphite crucible. The ultrasound Nb probe was inserted at the top of the crucible. The top of the crucible was also thermally insulated. Temperature measurements were performed at different locations in the crucible. The effects of ultrasound on the microstructure formation during solidification of A356 alloy was studied. A numerical model was developed to simulate the solidification process in the crucible and to assist in developing of solidification maps. In addition, with the help of machine learning techniques, the mutual interaction between Al-Si based alloys content, physical properties and processing parameters have been studied. Quantitative relationship equations and the significance of each key factors were developed and analyzed via machine learning, which helps to better understand the complex nonlinear relationship of alloy composition-physical properties-solidification processing parameters-mechanical performance in cast Al-Si based alloys. In the first chapter, the background of A356 alloy, ultrasonic stirring technology and the application of machine learning technique on metallurgical and materials engineering are introduced. The second chapter describes the methodology of the ultrasonic refining and modification mechanisms as well as several relevant machine learning algorithms that can be applied to study metallic materials. In the third chapter, the ultrasound effects on the formation of the solidification structure of A356 ingots processed via a 2-Zone induction melting furnace are studied. The fourth chapter focuses on modeling of segregation and microstructure evolution during the solidification of A356. Finally, in the fifth chapter a prediction of a quantitative relationship of alloys content-physical properties-processing parameters-mechanical properties using machine learning is performed.

Download or read book Solidification Behaviour of Al Sn Cu Immiscible Alloys and Al Si Cast Alloys Processed Under Intensive Shearing written by Hirenkumar R. Kotadia and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Alloy castings are usually solidified with a coarse columnar grain structure under normal casting conditions unless the mode of the solidification is carefully controlled. It is desirable for the grain structure to be fine and equiaxed to improve their mechanical performance as finished castings. It is possible to develop a fine and equiaxed grain structure either by increasing the number of nucleation sites or by grain multiplication. Immiscible alloys with a microstructure in which a soft phase is dispersed homogeneously in a hard matrix have significant potential applications in advanced bearing systems, especially for the automotive industry. Despite considerable efforts made worldwide, including extensive space experiments, no casting techniques so far can produce the desired immiscible microstructure of alloys. Experimental results on Al-Sn-Cu immiscible alloys have confirmed that intensive shearing using melt conditioning by an advanced shearing technology (MCAST) unit, is an effective way to achieve a fine and uniform dispersion of the soft phase without macro-demixing, and that such a dispersed microstructure can be further refined in alloys with precipitation of the primary Al phase prior to the demixing reaction. In addition, it was found that melt shearing at 200 rpm for 60 s will be adequate to produce a fine and uniform dispersion of the Sn phase, and that a higher shearing speed and prolonged shearing time can only achieve further minor refinement. A study of Al-Si hypoeutectic and hypereutectic alloys presents the effects of the processing temperature and intensive shearing on the microstructural and mechanical properties which have been investigated systematically. Attempts have been made to explain the solidification mechanism with intensive melt shearing. The sheared melt was cast into tensile test samples by high pressure die caster (HPDC) to examine the microstructures and mechanical properties. The experimental results reveal that significant grain refinement and uniformity of grains was achieved by the intensive shearing and also a considerable increase in mechanical properties with pouring temperature by changing intermetallic particles morphology, the position of defect band and reduced microscopic defects.
