Metal powders exhibit native oxide surface films which readily interact with ambient moisture to varying degrees. A series of typical metal powders used in AM powder bed fusion processes were exposed to various environmental conditions in order to control their moisture content. The bulk flow properties of the powders were then characterized using a drum-style avalanche powder flow analyzer. Precision moisture content was measured using oven desorption/evaporation coupled with Karl Fischer coulometric titration. The results of this study have implications on powder handling, recycling and AM process control.
MS&T 2021 featured three keynote speakers and 3.5 days of technical programming focused on key topics in emerging technology areas such as additive manufacturing, artificial intelligence and machine learning for materials, failure analysis, metallography, biomaterials, and much more. The event also included a comprehensive lineup of technical sessions, education courses, networking events, and an exhibit floor.
The conference theme, Where Materials Innovation Happens, featured programming specifically designed to appeal to materials professionals from industry, academia, and government. The conference’s featured content included NSL’s presentation regarding “Moisture Impacts in AM Metal Powders Characterized by Karl Fischer Oven Titration and Avalanche Rheometry”, which can be downloaded below. The conference is hosted annually.
The Materials Science & Technology (MS&T) technical meeting and exhibition is the long-standing, recognized forum for fostering technical innovation at the intersection of materials science, engineering, and application. Each year, MS&T brings together scientists, engineers, students, suppliers, and business leaders to discuss current research and technical applications and to shape the future of materials science and technology.
The event’s unmatched technical program addresses structure, properties, processing, and performance across the materials community. Its exhibition showcases a wide variety of equipment and services to the automotive, aerospace, instrumentation, medical, oilfield, and energy industries. MS&T is organized by a joint partnership of leading materials science-related societies, The American Ceramic Society (ACerS), The Association for Iron & Steel Technology (AIST), and The Minerals, Metals & Materials Society (TMS) Visit the individual conference web pages for more information and sign up for updates to stay informed of ongoing conference plans.
