Book Description :

The Complete Book on Ferroalloys (Ferro Manganese, Ferro Molybdenum, Ferro Niobium, Ferro Boron, Ferro Titanium, Ferro Tungsten, Ferro Silicon, Ferro Nickel, Ferro Chrome) An alloy is a mixture or solid solution composed of metals. Similarly, Ferroalloys are the mixture of Iron with high proportion of other elements like manganese, aluminium or silicon. Alloying improves the physical properties like density, reactivity, Young’s modulus, electrical and thermal conductivity etc. Ferroalloys thus show different properties as mixture of different metals in different proportion exhibit a wide range of properties. Also, Alloying is done to alter the mechanical properties of the base metal, to induce hardness, toughness, ductility etc. The main demand of ferroalloys, nowadays is continuously increasing as the major use of such products are in the field of civil construction; decorative items; automobile; steel industry; electronic appliances. The book provides a wide idea to readers about the usage of appropriate raw material and the treatment involved in the processing of raw material to final produce, safety, uses and properties of raw material involved in the processes. This book concisely presents the core principles and varied details involved in processing of ferroalloys. The work includes detailed coverage of the major products like ferroaluminium, ferrosilicon, ferronickel, ferromolybdenum, ferrotungsten, ferrovanadium, ferromanganese and lesser known minor ferroalloys. Progress in thermodynamics and physico-chemical factors in ferroalloy production has developed rapidly during the past twenty-five years or so. The book presents the principles and current knowledge of processes in the production of various ferroalloys. The production of a particular ferroalloy involves a number of processes to be followed in order to give the alloy desired physical and mechanical properties. The slight difference in the temperature or heating or composition can lead to entirely different alloy with different properties. This book is not only confined to the different processes followed in the production of ferroalloys but also describes the processes used and other information related to product, which are necessary for the manufacturer’s knowledge. Also, the book gives the reader appropriate knowledge regarding the selection the best of available raw materials.

Book Description :

Polycrystalline silicon (commonly called "polysilicon") is the material of choice for photovoltaic (PV) applications. Polysilicon is the purest synthetic material on the market, though its processing through gas purification and decomposition (commonly called "Siemens" process) carries high environmental risk. While many current optoelectronic applications require high purity, PV applications do not and therefore alternate processes and materials are being explored for PV grade silicon. Solar Silicon Processes: Technologies, Challenges, and Opportunities reviews current and potential future processing technologies for PV applications of solar silicon. It describes alternative processes and issues of material purity, cost, and environmental impact. It covers limits of silicon use with respect to high-efficiency solar cells and challenges arising from R&D activities. The book also defines purity requirements and purification processes of metallurgical grade silicon (MG-Si) and examines production of solar grade silicon by novel processes directly from MG-Si and/or by decomposition of silane gas in a fluidized bed reactor (FBR). Furthermore, the book: Analyzes past research and industrial development of low-cost silicon processes in view of understanding future trends in this field. Discusses challenges and probability of success of various solar silicon processes. Covers processes that are more environmentally sensitive. Describes limits of silicon use with respect to high-efficiency solar cells and challenges arising from R&D activities. Defines purity requirements and purification processes of MG-Si. Examines production of solar grade silicon directly from MG-Si.

Book Description :

Aluminium silicon alloys are the most used raw material for automotive applications. One of the main limitations on using aluminium high silicon alloys is the formation of coarse brittle phases under conventional solidification conditions. However, rapid solidification processing (RS) is very effective in limiting the coarsening of primary silicon due to high cooling rate. Aluminium high silicon alloys can be processed by different RS methods. However, melt spinning is the most familiar of all RS commercial methods. Rapid solidification is a material production route. It does not give the final shape. Rapidly solidified materials require consolidation after solidification. Moreover, consolidation requires mechanical and/or thermal treatment. These treatments may degrade the microstructure. Also hot extrusion may be used as a final step, which may cause deterioration of the initially useful properties due to hot working. In general, although rapid solidification may suppress the coarsening of Si during solidification, the Si particulates may still coarsen during the subsequent thermo-mechanical treatment due to heat effect during consolidation and extrusion. In the present work characterisation of the material at various stages of production has been carried out and understanding of the metallurgical phenomena involved. Several alloy variants were examined. Coarsening behaviour of the Silicon particles and hardness tests were carried out. Wear properties of the alloys have been studied under dry sliding conditions against a steel ball bearing. Analyses and observation of the wear surfaces and wear mechanisms of these alloys are discussed. Wear of RS materials was compared with piston material A390 made by casting. Degassing and HIPping at 400 °C for 12 hrs prior to HIPping seems to be the optimum the degassing is effective whilst avoiding excessive coarsening of the silicon particles. Alloy number RSP461 (Al 21Si 3.9Cu 1.2Mg 2.4Fe 1.4Ni 0.4Zr) shows excellent wear resistance due to its fine microstructure.
