“…These factors combine to cause the formation of large columnar grains in cast product. This grain structure limits the mechanical properties of cast Be to ultimate tensile stress values of 34 to 68 MPa and nil ductility [2]. In order to control grain size and improve mechanical properties, Be is typically processed by making powder, consolidating it by vacuum hot pressing, and machining parts from the hot pressed log.…”

SUPPLEMENTARY NOTESSubmitted for publication in International Thermal Spray Conf., 15 May 05, Seattle, WA Government Purpose Rights ABSTRACTThe exceptional properties of beryllium (Be) including low density and high elastic modulus, make it the materials of choice in many defense and aerospace applications. However, health hazards associated with Be material handling limit the applications that are suited for beryllium use. Innovative solutions that enable continued use of Be in critical applications while addressing worker health concerns are highly desirable. Plasma Transferred Arc solid freeform fabrication is being evaluated as a Be fabrication technique for civilian and military space based components. Initial experiments producing beryllium deposits are reported here. Deposit shape, microstructure and mechanical properties are reported.
