Abstract:

The paper discusses recent improvements in beryllium in terms of its basic deformation and alloying behavior. Recent advances in beryllium are attributable to three factors in addition to impurity control 1 powder production by impact attritioning 2 consolidation of isotropic material by hot isostatic compaction and 3 development of plasma spraying as a consolidation technique. Properties attainable in these materials are discussed. Further evaluations of these materials under biaxial and dynamic load conditions are required. Fabrication and testing of structures under simulated load conditions are recommended. Modified author abstract
