Book Description
Powder metallurgy (PM) manufacture of parts is one of the most energy and material efficient forms of net-shape production, particularly, for automotive industry. PM allows repeatable mass production which makes it unique. However, it is well known that the quality of sintered parts can be variable. There can be typically around a 5% scrap rate in existing PM manufacturing lines. Current efforts are being made to develop non-destructive testing (NDT) techniques that will allow inspection of PM parts, notably sintered ones ideally in line with production to increase the quality of output batch and reduce scrap, as much as possible. This chapter presents an overview of non-destructive evaluation methods for PM components. It also seeks to capture latest NDT strategies such as digital radiography (DR) and identify apparent technology gaps in NDT of PM parts, in terms of applicability issues, with an emphasis on offering solutions to detection problems. It also seeks to highlight future work.

Book Description
Ferrous powder metallurgy (PM) makes up the majority of powder metallurgy products with regard to tonnage. Improving performance is the main trend for pressed and sintered parts, in particular the introduction of cost-effective alloy elements such as Cr and Mn. Furthermore, much can be gained in ferrous PM by elaborate secondary operations. In metal injection moulding (MIM) products, there is a clear trend towards increasingly complex shapes and microsized parts. PM tool steels offer a much finer and fully isotropic microstructure compared to their wrought counterparts and the carbide content may be much higher, resulting in excellent application properties.

Book Description
Since the early 1990s considerable effort has been devoted to the development of metal-based composite powders (MeCP). Reinforcements in MeCP can vary from intermetallic to ceramic or polymer, depending on composition and can also be microstructured or nanostructured, depending on the size of the constituent materials. Composite powders can be used at the macro- and microscale to produce dense composite objects, composite coatings, to provide a combination of properties in one component or to provide specific properties to withstand extreme conditions in service. In addition to this, technology for the synthesis of nanodevices has also evolved. Metal composite powders are produced by a variety of methods based on solid-, liquid- and gas-phase synthesis and mechanosynthesis. Functionality and design are the current drivers for the development of metal composite powders.

Book Description
This book is focused on composites involving powders as the starting materials. It provides relevant information for questions related to the selection of constituent phases, most economic fabrication routes, proper testing procedures, and product optimization. The field is sufficiently advanced that predictive models guide many decisions. Applications are illustrated over a broad range of material and property combinations. This title includes: •Selection of phases with consideration of intersolubility & interface •Microstructure, especially the role of phase connectivity •Fabrication approaches, especially net-shape consolidation •Assessment of typical properties, testing techniques & industry standards •Design & trade-off decisions involved in optimization, including cost •Applications, both those that have matured and some emerging prospects. The reader may have little appreciation for how particulate composites are literally everywhere. Examples include new wear resistant consumer products(Apple watch), longer lasting automotive tires with reduced rolling resistance(Yokohama tires), and new diamond heat sinks for computers(Element Six substrates). Particulate composites also form critical components in applications such as magnets, dental fillings, brakes, darts, bio-implants, & cutting tools. Particulate composites are a multi-billion dollar industry, and can be a cost-effective solution ripe for innovation and continued rapid growth. For the engineer, the wide range of particulate composite formulation and property combinations offers the ability to design for a variety of application and provides ample opportunity for innovation. Particulate Composites: Fundamentals & Applications is ideal for use in a one-semester eng. course at the senior UG/graduate level, and is also suitable as a practical reference for materials scientists in academia and industry.

Book Description
Using microwaves to treat metal-based materials is rapidly emerging as an energy-efficient tool to interact with metals for a number of processes such as sintering, melting, brazing, carburizing and annealing. Microwaves can sinter a wide variety of metal compacts with comparable or enhanced end properties, while at the same time delivering tremendous energy savings over conventional sintering. Microwave processes are therefore gaining increasing attention and adoption in both academia and industry. Gupta and Wong have written this comprehensive text to introduce readers to the world of microwaves and the interaction of microwaves with metals and metals-based formulations. The authors have combined numerous research results from a wide range of sources alongside their own work in the field. Also included are overviews of microwave heating of other non-metal materials and the equipment used for microwave-assisted metallurgy. With microwave techniques poised for widespread adoption, Microwaves and Metals is an essential text for all metallurgists and materials engineers. Provides a thorough grounding in microwave fundamentals and their application to metals processing Informs readers of the latest developments in the field Presents a convenient single source for all aspects of microwave processing of metals and materials Contains liberal illustration to compare and benchmark research results Introduces all the necessary equipment, preparing readers for real-world practice Microwaves and Metals is ideal for a post-graduate or advanced undergraduate course in materials science or metallurgy.
