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.
Claims20
A method of manufacturing an object comprising beryllium, the method comprising:
- preparing a mixture of beryllium powder and at least one metal inoculant;
- depositing a layer comprising the mixture on a surface;
- applying energy to at least a portion of the layer to form molten beryllium in a reducing atmosphere;
- solidifying the molten beryllium into a layer comprising a continuous beryllium matrix having a crystalline structure of equiaxed grains;
- and
- repeating the depositing/applying/solidifying for successive layers until the object having a geometric shape is achieved.

A method of grain refining an object comprising beryllium, the method comprising:
- combining beryllium and at least one metal inoculant selected from the group consisting of Be2Co, Be2Nb, Be2Ta, Be2Ti, Be2W, Be5Hf, Be5Sc, Be5Zr, Be7Cu13, BeFe3, Cu3Mo, Cu9W, Mo, Nb, RbO2, ReRh, Ta, TiV, and W to form a pre-alloy composition;
- depositing a layer comprising the pre-alloy composition on a surface;
- cycling at least a portion of the layer by applying energy to form molten beryllium;
- solidifying the molten beryllium;
- and
- repeating the depositing/cycling/precipitating for successive layers, wherein each of the successive layers comprise the pre-alloy composition and have an average grain size from 1 to 80 microns.

An object comprising:
- beryllium, wherein the beryllium is in a crystalline structure comprising equiaxed grains of beryllium;
- and
- at least one metal inoculant selected from the group consisting of Be2Co, Be2Nb, Be2Ta, Be2Ti, Be2W, Be5Hf, Be5Sc, Be5Zr, Be7Cu13, BeFe3, Cu3Mo, Cu9W, Mo, Nb, RbO2, ReRh, Ta, TiV, and W to form a grains that are 1:1 or 2:1 lattice match to the beryllium grains;
- wherein the equiaxed grains of beryllium has an average grain size from 1 to 80 microns.
