• Crack-free pure molybdenum is fabricated via electron beam melting AM. Fiber texture switching observed across various energy density settings. The weld pool shape likely drives the fiber selection mechanism. Columnar grains consist of fine subgrains believed to be due process stresses. Additive manufacturing (AM) technologies offer novel opportunities for processing difficult cast refractory materials. Electron (EBM) AM particularly attractive as rapidly moving can utilized heat powder...
Additive manufacturing processes supplement traditional material processing routes with unique capabilities which can have profound impacts on component production. Physical prototyping is accelerated and the fabrication of complex components, difficult or impossible to produce conventionally, realized. Metals research often focused identifying process windows avoid defects thereby yield desirable properties. In electron beam melting fusion processes, however, precise spatial control heat...
Abstract Realizing application specific manufacture with fusion-based additive manufacturing (F-BAM) processes requires understanding of the physical phenomena that drive evolution microstructural attributes, such as texture. Current approaches for texture in F-BAM are majorly considerate occurring only during solidification. This hinders comprehensive and control F-BAM. In this perspective article, we discuss several after solidification can determine processed stainless steels (SS). A...
Abstract Machining is a severe plastic deformation process, wherein the workpiece material subjected to high rates and temperatures. During metal machining, dynamic recrystallization mechanism causes grain refinement into sub-micron range. In this study, we investigate microstructure evolution of oxygen-free conductivity copper (OFHC Cu) subject machining process where cutting speed rake angle are controlled manipulate strain, strain rate, Microstructures deformed chips quantified using...
