Titanium Powder Metallurgy

Titanium Powder Metallurgy contains the most comprehensive and authoritative information for, and understanding of, all key issues of titanium powder metallurgy (Ti PM). It summarizes the past, reviews the present and discusses the future of the science and technology of Ti PM while providing the world titanium community with a unique and comprehensive book covering all important aspects of titanium powder metallurgy, including powder production, powder processing, green shape formation, consolidation, property evaluation, current industrial applications and future developments. It documents the fundamental understanding and technological developments achieved since 1937 and demonstrates why powder metallurgy now offers a cost-effective approach to the near net or net shape fabrication of titanium, titanium alloys and titanium metal matrix composites for a wide variety of industrial applications. Provides a comprehensive and in-depth treatment of the science, technology and industrial practice of titanium powder metallurgy Each chapter is delivered by the most knowledgeable expert on the topic, half from industry and half from academia, including several pioneers in the field, representing our current knowledge base of Ti PM. Includes a critical review of the current key fundamental and technical issues of Ti PM. Fills a critical knowledge gap in powder metal science and engineering and in the manufacture of titanium metal and alloys

Powder metallurgy of titanium and titanium alloys has been increasingly attracting attention of engineers and researchers for over four decades and the 4th International Conference on Titanium Powder Metallurgy & Additive Manufacturing (PMTi 2017, Xi’an, China, from 8 to 10 September 2017) was an event that promoted the progress in this area of the materials science and processing technologies.

The conference upon which this work is based fully achieved its objectives and turned out to be the largest international gathering dedicated solely to the topic of titanium processing via powder metallurgy. Volume is indexed by Thomson Reuters CPCI-S (WoS). The 50 peer-reviewed papers are grouped into 8 chapters: PM titanium alloy design and processing developments; Powder Production; Effect of Impurities; Metal Injection Moulding of Titanium; Biomedical Titanium Alloys; Titanium Composites; Forging and Equal-Channel Angular Pressing of Titanium; Laser Cladding, Welding, Slip Casting and Other Processing Developments.

This new book covers all aspects of the history, physical metallurgy, corrosion behavior, cost factors and current and potential uses of titanium. The history of titanium is traced from its early beginnings through the work of Kroll, to the present day broadening market place. Extensive detail on extraction processes is discussed, as well as the various beta to alpha transformations and details of the powder metallurgy techniques.

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 for sputtering targets, coating, as a grain refiner in aluminium alloys and fireworks are not addressed.

This book comprises 49 papers presented by international experts from 25 countries on the conference PM Titanium 2015 in Lüneburg, Germany. It gives a comprehensive overview on the technical and scientific status in the field of powder metallurgy of titanium and titanium alloys and points out the most important current research topics in this emerging area. The content covers powder production technologies, processing techniques like additive manufacturing, spark plasma sintering and metal injection moulding, specific application fields like biomaterials and special alloys, microstructures and properties. The conference was the third one of a series of biennial conferences on Powder Pressing, Consolidation and Metallurgy of Titanium, initiated 2011 in Brisbane, Australia.
