Available in PDF, EPUB and Kindle. Book excerpt: Laser powder bed fusion of metals is a technology that makes use of a laser beam to selectively melt metal powder layer-by-layer in order to fabricate complex geometries in high performance materials. The technology is currently transforming aerospace and biomedical manufacturing and its adoption is widening into other industries as well, including automotive, energy, and traditional manufacturing. With an increase in design freedom brought to bear by additive manufacturing, new opportunities are emerging for designs not possible previously and in material systems that now provide sufficient performance to be qualified in end-use mission-critical applications. After decades of research and development, laser powder bed fusion is now enabling a new era of digitally driven manufacturing. Fundamentals of Laser Powder Bed Fusion of Metals will provide the fundamental principles in a broad range of topics relating to metal laser powder bed fusion. The target audience includes new users, focusing on graduate and undergraduate students; however, this book can also serve as a reference for experienced users as well, including senior researchers and engineers in industry.

Download or read book Laser Cladding of Metals written by Pasquale Cavaliere and published by Springer Nature. This book was released on 2020-11-05 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser cladding is an additive manufacturing technology capable of producing coatings due to the surface fusion of metals. The selected powder is fed into a focused laser beam to be melted and deposited as coating. This allows to apply material in a selected way onto those required sections of complex components. The process main properties are the production of a perfect metallurgically bonded and fully dense coatings; the minimal heat affected zone and low dilution between the substrate and filler material resulting in functional coatings that perform at reduced thickness, so fewer layers are applied; fine, homogeneous microstructure resulting from the rapid solidification rate that promotes wear resistance of carbide coatings; near net-shape weld build-up requires little finishing effort; extended weldability of sensitive materials like carbon-rich steels or nickel-based superalloys that are difficult or even impossible to weld using conventional welding processes; post-weld heat treatment is often eliminated as the small heat affected zone minimizes component stress; excellent process stability and reproducibility because it is numerical controlled welding process. The typical applications are the dimensional restoration; the wear and corrosion protection; additive manufacturing. The wide range of materials that can be deposited and its suitability for treating small areas make laser cladding particularly appropriate to tailor surface properties to local service requirements and it opens up a new perspective for surface engineered materials. The main key aspect to be scientifically and technologically explored are the type of laser; the powders properties; the processing parameters; the consequent microstructural and mechanical properties of the processed material; the capability of fabrication of prototypes to rapid tooling and rapid manufacturing. Distills critical concepts, methods, and applications from leading full-length chapters, along with the authors’s own deep understanding of the material taught, into a concise yet rigorous graduate and advanced undergraduate text; Reinforces concepts covered with detailed solutions to illuminating and challenging industrial applications; Discusses current and future applications of laser cladding in additive manufacturing.

Download or read book Nuclear Pumped Lasers written by Mark Prelas and published by Springer. This book was released on 2015-11-20 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on Nuclear-Pumped Laser (NPL) technology and provides the reader with a fundamental understanding of NPLs, a review of research in the field and exploration of large scale NPL system design and applications. Early chapters look at the fundamental properties of lasers, nuclear-pumping and nuclear reactions that may be used as drivers for nuclear-pumped lasers. The book goes on to explore the efficient transport of energy from the ionizing radiation to the laser medium and then the operational characteristics of existing nuclear-pumped lasers. Models based on Mathematica, explanations and a tutorial all assist the reader’s understanding of this technology. Later chapters consider the integration of the various systems involved in NPLs and the ways in which they can be used, including beyond the military agenda. As readers will discover, there are significant humanitarian applications for high energy/power lasers, such as deflecting asteroids, space propulsion, power transmission and mining. This book will appeal to graduate students and scholars across diverse disciplines, including nuclear engineering, laser physics, quantum electronics, gaseous electronics, optics, photonics, space systems engineering, materials, thermodynamics, chemistry and physics.
Download or read book Worlds Apart written by James Wittenbach and published by Booktango. This book was released on 2015-08-31 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been nearly 5 years since the Pathfinder Ship Pegasus left the Eventide system; more than a century since it entered the Orion Quadrant on its quest to find Earth. The worlds it has called upon have been, in turn, abandoned, primitive, and desolate. At Eventide, the crew of Pegasus detected a signal and decided to follow it. They hope it will lead to an opportunity to reconnect with their homeworlds. In fact, the signal is calling the ship to its end. A lot has changed in the galaxy since the ship left its home quadrant. Those now in power have determined that Pegasus is an obsolete relic of another Era. Its mission to find Earth is no longer important. Pegasus is to be decommissioned, its crew scattered, its mission concluded. Some of the crew refuse to accept this destiny, and will resort to defiance, mutiny, even sabotage to prevent it. At the center of the storm, Lt. Commander David Alkema finds himself caught in the crosswinds of personal ambition, family drama, dirty politics, and forbidden lust. Saving his ship may require sacrificing everything and everyone he loves. What will be the final destiny of Pegasus? Scrapyard? Museum? Orbital brothel? Or, will the ship live to fight another day against something more terrible than any of them can imagine. The eleventh and penultimate Worlds Apart book is about the way fate smashes through our best-laid plans like a Tyrannosaurus Rex through a church window, shattering them into fragments that glitter in the light just long enough to taunt us with what almost was before they fall to the ground and ruin it for everybody who was planning on going barefoot.
