Abstract : A program plan for evaluating beryllium/titanium composite materials with respect to method of manufacture, v/o Be extrusion and forging reduction is presented. Coextruded Be/Ti powders, as well as coextruded Be rod with a wrought Ti matrix was investigated. The most cost effective material/process was characterized and design criteria properties determined for gas turbine for gas turbine fan/compressor blades applications. The material from each vendor was received, isothermally forged and tensile tested at room temp. and 600F. Based on the tensile results and metallographic examination one type was selected for further property characterization. This characterization included creep, high and low cycle fatigue and ballistic impact.
