Is the shift to renewable energy and digital devices going to free us from severe pollution, material shortages, and military tensions? Rare metals are essential to electric vehicles, fighter jets, wind turbines, and solar panels, and also to our smartphones, computers, tablets, and other everyday connected objects. But consumers know very little about how they are mined and traded, or the environmental, economic, and geopolitical costs of this dependence. This book reveals the dark side of the world that awaits us. It is an undercover tale of a technological odyssey that has promised much, and a look behind the scenes. Behind it all lurks China, which has captured the lion's share of the ownership and processing of rare metals we now can't do without. Drawing on six years of research across a dozen countries, this book shows that by breaking free of fossil fuels, we are in fact setting ourselves up for a new dependence--on rare metals that have become vital to our new ecological and digital society.

Rare Earth Elements are a group of 17 metals which have a central role in modern industry, increasingly used in the fields of green technologies, high technological consumer goods, industrial and medical appliances and modern weapons systems. Although deposits of Rare Earths are globally dispersed, over 90% of global demand has been provided by Chinese mines since the late 1990s, leading to a situation where China has a virtual monopoly. This book surveys the Rare Earths mining industry, discusses the extent to which Rare Earths really are scarce elsewhere in the world and assesses the economics of production, considering arguments for the rationing of supply, for higher pricing and for a total export embargo. This actually occurred in 2010, demonstrating the vulnerability of the rest of the world to China’s control of these increasingly vital resources.

In World Trade Systems of the East and West , Geoffrey C. Gunn profiles Nagasaki's historic role in mediating the Japanese bullion trade, especially silver exchanged against Chinese and Vietnamese silk. Founded in 1571 as the terminal port of the Portuguese Macau ships, Nagasaki served as Japan's window to the world over long time and with the East-West trade carried on by the Dutch and, with even more vigor, by the Chinese junk trade. While the final expulsion of the Portuguese in 1646 characteristically defines the “closed” period of early modern Japanese history, the real trade seclusion policy, this work argues, only came into place one century later when the Shogunate firmly grasped the true impact of the bullion trade upon the national economy.

Multiscale Modeling of Additively Manufactured Metals: Application to Laser Powder Bed Fusion Process provides comprehensive coverage on the latest methodology in additive manufacturing (AM) modeling and simulation. Although there are extensive advances within the AM field, challenges to predictive theoretical and computational approaches still hinder the widespread adoption of AM. The book reviews metal additive materials and processes and discusses multiscale/multiphysics modeling strategies. In addition, coverage of modeling and simulation of AM process in order to understand the process-structure-property relationship is reviewed, along with the modeling of morphology evolution, phase transformation, and defect formation in AM parts. Residual stress, distortion, plasticity/damage in AM parts are also considered, with scales associated with the spatial, temporal and/or material domains reviewed. This book is useful for graduate students, engineers and professionals working on AM materials, equipment, process, development and modeling.

Quality Analysis of Additively Manufactured Metals: Simulation Approaches, Processes, and Microstructure Properties provides readers with a firm understanding of the failure and fatigue processes of additively manufactured metals. With a focus on computational methods, the book analyzes the process-microstructure-property relationship of these metals and how it affects their quality while also providing numerical, analytical, and experimental data for material design and investigation optimization. It outlines basic additive manufacturing processes for metals, strategies for modeling the microstructural features of metals and how these features differ based on the manufacturing process, and more. Improvement of additively manufactured metals through predictive simulation methods and microdamage and micro-failure in quasi-static and cyclic loading scenarios are covered, as are topology optimization methods and residual stress analysis techniques. The book concludes with a section featuring case studies looking at additively manufactured metals in automotive, biomedical and aerospace settings.
