Abstract: Methods for manufacturing a beryllium-based article object comprising beryllium by depositing layers of beryllium. An element is added to the beryllium that dissolved to form a secondary phase to limit columnar grain. Grain refinement allows the beryllium article to have beneficial properties in terms of strength and durability.

Abstract: Methods for manufacturing an object comprising beryllium by depositing layers of beryllium and metal inoculants are disclosed. Grain refinement allows the beryllium article to have beneficial properties in terms of strength and durability.

Abstract: Methods for grain refinement of beryllium articles are disclosed. Grain refinement allows the beryllium article to have beneficial properties in terms of strength and durability. One method stabilizes the ?-phase of the beryllium that is precipitated after cycling above a temperature that is greater than or equal to the beta transus temperature.

Abstract: Methods for grain refinement of beryllium articles are disclosed. Grain refinement allows the beryllium article to have beneficial properties in terms of strength and durability. The method disclosed herein provide for efficient grain refinement using in situ formed intermetallic compounds of beryllium.

Abstract: The present disclosure relates to piston assembly comprising a piston having a circumferential groove and a ring groove insert within the circumferential groove of the piston. Particularly, the ring groove insert is a second material different from a first material of the piston. The second material has at least one of the following: a) a density from 90% to 120% of a density of the first material; b) a coefficient of thermal expansion (CTE) from 50% to 90% of a CTE of the first material; or c) a thermal conductivity greater than a thermal conductivity of the first material.
