Five years ago, the worldwide powder metallurgy fraternity gathered in New York City to attend the first international conference devoted entirely to powder metal lurgy to take place in the United States. It was a tentative venture, entered into by the sponsors with no idea as to whether it would fail or succeed. The only assurances we had were that the metal-powder producing and consuming industries were rapidly expanding and that powder metallurgy was truly becoming one of the international

Powder metallurgy (PM) is a popular metal forming technology used to produce dense and precision components. Different powder and component forming routes can be used to create an end product with specific properties for a particular application or industry. Advances in powder metallurgy explores a range of materials and techniques used for powder metallurgy and the use of this technology across a variety of application areas. Part one discusses the forming and shaping of metal powders and includes chapters on

Powder metallurgy (PM) processes are ideal for rapid production of near net shape parts with complex geometries from a range of materials that would often not be possible to combine otherwise. Certain alloy combinations, chemical compositions in powder form are more favourable for synthesis of materials. This allows PM to be extremely versatile, maximising material utilisation. The net shape capability directly reduces or eliminates secondary operations like machining. Despite this obvious advantage of PM processes, joining materials synthesised from powders

Warm compaction is a cost saving and effective method for obtaining high performance powder metallurgy (PM) parts. This chapter presents the principles of warm compaction and technical aspects of the process. The green and sintered properties of warm compacted parts are discussed and compared with conventionally (cold) produced compacts. The applications of the process for ferrous and non-ferrous PM parts are presented and future trends are outlined.

Sintered ferrous powder metallurgy (PM) components are replacing wrought alloys in many applications, owing to their low cost, high performance and ability to be processed to near-net shape. The fracture and fatigue behavior of these materials is very important. In this chapter the microstructure, tensile and fatigue behavior of sintered steels is reviewed.

This chapter is a review of recent developments (since 2000) and aims to provide the reader with an introduction to a range of atomisation techniques developed in the last century, in order to understand the latest developments. The basic principles of gas, water and centrifugal atomisation are covered, followed by discussion of problems and advances in each area. The chapter will not attempt to cover all the classical techniques in detail. A previous review or major book can be consulted for

Metal injection moulding (MIM) is a manufacturing process used for small-to-medium-shaped precision components. This chapter provides a detailed overview of MIM and includes descriptions of the principles of the process such as powders, binders, mixing and feedstock analysis, injection moulding, binder removal (debinding), sintering and post-sintering. The chapter concludes with case studies and the design requirements for MIM and its applications.

The major reason that there is not more widespread use of titanium and its alloys is the high cost. In this paper, developments in one cost effective approach to fabrication of titanium components – powder metallurgy – is discussed with respect to various aspects of this technology. These aspects are the blended elemental approach, prealloyed techniques, additive layer manufacturing, metal injection molding, spray deposition, far from equilibrium processing (rapid solidification mechanical alloying and vapor deposition) and porous materials. Use of titanium powder

This chapter introduces the novel method of mechanochemical synthesis as an effective method for synthesizing metal powders in the nanocrystalline state. After introducing the basic principles of the process, process parameters that affect the constitution and microstructure of the processed powders are discussed. The mechanisms of alloying and grain refinement are also described. Methods for achieving the smallest possible grain size are highlighted. Current problems associated with the consolidation of powders to bulk shape are described. The ubiquitous problem of

This chapter introduces the concept of optimization in the area of component manufacturing. A short introduction explains the associated concepts, applications, formats and approaches and familiarizes the reader with the terminology. The main body of the chapter examines approaches to optimization in four different component manufacturing applications: die compaction process design, powder injection moulding process design, sintering process design and steady-state conduction design. The methodologies used in the applications include both mathematical iterative methods and experimental optimization methods.

This chapter describes the processing and properties of metals containing significant fractions of porosity, processed using powders. The basic concepts used in porous materials research are introduced and the different types of processing techniques that have been explored are surveyed. The reported property data for different foams are collated and used to illustrate the range of properties that have been achieved and methods to predict the properties of porous metals from elementary knowledge about their structure are discussed. Finally, the
