NSF-BSF Influences of cohesion enhancing elements, impurities and hydrogen or deuterium at grain boundaries and heterophase interfaces on embrittlement (ductilization) of steels

Project: Research project

Project Details


A study of an additive manufactured (AM) special steel designed specifically for AM, which involves first having this steel atomized by a commercial company. The powders will then be used to print 3-D specimens through the use of a SLM machine at Northwestern University and also at Tel Aviv University using a DED (LENS) machine. The fabricated products will then be hydrogenated and also deuterated to introduce hydrogen or deuterium in them. Mechanical property measurements will be made on these fabricated products to study the effects of hydrogen and deuterium. Specifically, whether or not the fabricated products are embrittled by hydrogen and deuterium.
