This book shares insights on post-processing techniques adopted to achieve precision-grade surfaces of additive manufactured metals including material characterization techniques and the identified material properties. Post-processes are discussed from support structure removal and heat treatment to the material removal processes including hybrid manufacturing. Also discussed are case studies on unique applications of additive manufactured metals as an exemplary of the considerations taken during post-processing design and selection. Addresses the critical aspect of post-processing for metal additive manufacturing Provides systematic introduction of pertinent materials Demonstrates post-process technique selection with the enhanced understanding of material characterization methods and evaluation Includes in-depth validation of ultra-precision machining technology Reviews precision fabrication of industrial-grade titanium alloys, steels, and aluminium alloys, with additive manufacturing technology The book is aimed at researchers, professionals, and graduate students in advanced manufacturing, additive manufacturing, machining, and materials processing.
Additive manufacturing (AM), also known as 3D printing, has gained significant interest in aerospace, energy, automotive and medical industries due to its capabilities of manufacturing components that are either prohibitively costly or impossible to manufacture by conventional processes. Among the various additive manufacturing processes for metallic components, electron beam melting (EBM) and selective laser melting (SLM) are two of the most widely used powder bed based processes, and have shown great potential for manufacturing high-end critical components, such as turbine blades and customized medical implants. The futures of the EBM and SLM are doubtlessly promising, but to fully realize...
Zi Zhi Tong Jian (Chinese: 资治通鉴;English: "Comprehensive Mirror in Aid of Governance") is a pioneering reference work in Chinese historiography, published in 1084 in the form of a chronicle. In 1065 AD, Emperor Yingzong of Songordered the great historian Sima Guang (1019–1086 AD) to lead with other scholars such as his chief assistants Liu Shu, Liu Ban and Fan Zuyu,[1] the compilation of a universal history of China. The task took 19 years to be completed,and, in 1084 AD, it was presented to his successor Emperor Shenzong of Song. The Zizhi Tongjian records Chinese history from 403 BC to 959 AD, covering 16 dynasties and spanning across almost 1,400 years,and contains 294 volumes (...

The Sinitic Civilization A Factual History through the Lens of Archaeology, Bronzeware, Astronomy, Divination, Calendar and the Annals The book covered the time span of history of the Sinitic civilization from antiquity, to the 3rd millennium B.C. to A.D. 85. A comprehensive review of history related to the Sinitic cosmological, astronomical, astrological, historical, divinatory, and geographical developments was given. All ancient Chinese calendars had been examined, with the ancient thearchs’ dates examined from the perspective how they were forged or made up. The book provides the indisputable evidence regarding the fingerprint of the forger for the 3rd century A.D. book Shangshu (remot...

Old Beijing has become a subject of growing fascination in contemporary China since the 1980s. While physical remnants from the past are being bulldozed every day to make space for glass-walled skyscrapers and towering apartment buildings, nostalgia for the old city is booming. Madeleine Yue Dong offers the first comprehensive history of Republican Beijing, examining how the capital acquired its identity as a consummately "traditional" Chinese city. For residents of Beijing, the heart of the city lay in the labor-intensive activities of "recycling," a primary mode of material and cultural production and circulation that came to characterize Republican Beijing. An omnipresent process of recycling and re-use unified Beijing's fragmented and stratified markets into one circulation system. These material practices evoked an air of nostalgia that permeated daily life. Paradoxically, the "old Beijing" toward which this nostalgia was directed was not the imperial capital of the past, but the living Republican city. Such nostalgia toward the present, the author argues, was not an empty sentiment, but an essential characteristic of Chinese modernity.
