Abstract : The current program is designed to develop a method for extruding a cast beryllium-aluminum composite, establish a basis for estimating the properties that can ultimately be achieved with an optimized process, and produce an extruded structural shape of moderate complexity. Specific technical objectives are as follows: 1. Develop an extrusion process suitable for beryllium-aluminum composites that maximizes product yield, minimizes processing steps, gives good surface finish, and is suited for producing complex shapes. 2.Determine mechanical and physical properties to demonstrate potential. 3. Define potential for property enhancements and cost reductions that could be achieved through continued development of this technology.
