ALUMINUM-BERYLLIUM ALLOYS FOR AEROSPACE APPLICATIONS D. Hashiguchi,A.N.Ashurst, F. C. Grensing, J.M. Marder Materion Beryllium & Composites ABSTRACT A family of low density - high elastic modulus aluminum-beryllium alloys is under development in order to meet the requirements of advanced aerospace designs. These alloys are aluminum based with 10%-75% beryllium and combine the high specific stiffness of beryllium with the ductility and ease of fabrication of aluminum. Densities ranging from 2.0 to 2.58 g/cc with excellent strength and ductility have been achieved. The family of AlbeMet™ alloys under development was manufactured by both powder and ingot metallurgy techniques. Property characterization of extruded bar and rolled sheet included tensile, fatigue and fracture mechanics evaluation.The dependence of microstructure and properties upon composition and fabrication method, as well as upon third element additions is described. Keywords:AlbeMet™,Aluminum,Aluminum-Beryllium Alloy, Beryllium, Lightweight, Modulus 1. INTRODUCTION Development work performed in the 1960’s1 showed that the Al-Be alloy system had the potential to produce a family of lightweight materials with the combined attributes of the high modulus and strength of beryllium and high ductility and fracture toughness of aluminum. Beryllium is one of the lightest aerospace structural materials with a density of 1.85 g/cc (0.067 lb/cu.in.) while aluminum’s density is approximately 45% higher at 2.7 g/cc (0.097 lb/cu.in.). Aluminum and beryllium form a eutectic at a composition of 2.5%Al and a temperature of 644ºC (1191ºF)2 . The terminal solid solution shows highly limited solubility of beryllium in aluminum and no solubility of aluminum in beryllium (Figure 1). This gives rise to the potential to treat the alloy as a composite engineered material. Prior data published3 on rolled P/M Al-62wt%Be (Table 1), showed typical properties of the alloy after heat treatment at 600ºC (1100ºF). 2. PROCEDURE Aluminum-Beryllium alloys of three compositions were produced by powder and ingot metallurgy methods. The compositions investigated included Al-20wt%Be, Al-40wt%Be and Al-62wt%Be. The aluminum used as reference for the study was grade AA1100 which is 99% minimum pure. Aluminum from grade AA6061 was used to make minor additions of third element additions such as magnesium and silicon in the ingot cast material. 2.1 Powder Metallurgy Two compositions were studied using the powder metallurgy approach. Inert gas atomization was used to produce prealloyed Al-Be particles. These particles exhibited a fine dispersion of Al and Be (Figure 2). The typical beryllium dendrite size was on the order of 1 to 10 microns. Typical -100 mesh (
