Abstract
A method for enhancing the mechanical properties of beryllium and beryllium alloy bodies by deforming and recrystalizing cast and hot pressed beryllium bodies to a finer grain microstructure than initially present in the bodies without introducing a pronounced crystallographic texture into the bodies. More particularly, the beryllium body undergoes a textureless forging process by which the body is plastically deformed at elevated temperatures with the resulting metal flow being restricted to only one axis of the body. The deformed body is then restored to essentially its original shape and annealed at its recrystalization temperature with a resulting refinement in grain size to a size smaller than that present in the initial body.
