摘要： A method for enhancing the mechanical properties of cast beryllium and beryllium alloy bodies by reducing beryllium grain size. More particularly, grain size is reduced by forming a metal beryllide phase that is soluble in molten beryllium but of limited solubility in the solid metal. Initially, molten beryllium is cast into a mold and solidified resulting in precipitation of the metal beryllide in the form of finely divided particles at the beryllium grain boundaries. The cast body is then mechanically worked below its recrystallization temperature to form an unstable, deformed microstructure which is converted to a fine grain microstructure during a subsequent anneal above the recrystallization temperature of the beryllium or beryllium alloy body. The anneal can be a separate operation or a continuation of the plastic deformation operation.

摘要： 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.
摘要翻译：通过将铸造和热压铍体变形和重结晶到比最初存在于本体中更精细的晶粒微结构来提高铍和铍合金体的机械性能的方法，而不向体内引入明显的结晶学质感。更具体地，铍体经历无纹理的锻造工艺，通过该方法，身体在升高的温度下塑性变形，所得的金属流被限制在仅一个身体的一个轴线上。然后将变形体恢复到其原始形状并在其重结晶温度下退火，从而使得晶粒尺寸的细化至小于初始体内存在的尺寸。
