An alloy consisting of at least 50% of Be with the remainder being Al has a Be rich phase and an Al rich phase the Be rich phase being in the form of a generally particulate irregularly shaped network with which is interspersed the Al rich phase, and the alloy has a complexity index between 1 and 5. The alloy may be made by compacting Al coated Be particles or powder or Al-Be alloy powder or particles, outgassing the compact and pressing, all the operations being conducted below 1193 DEG F. The pressed compact (e.g. formed by extrusion of the compacted billet) may be annealed at 1100 DEG -1193 DEG F. rolled into sheet and further annealed at 1150 DEG -1193 DEG F. The Al-Be alloy powder may be made by atomizing a melt thereof with an inert or slightly reactive gas, or through a nozzle or on an atomizing wheel or by blowing a stream of the melt on to a cold surface by means of a pressurized gas jet. |
