Abstract
A method of making an article includes depositing a plurality of layers to form a three-dimensional preform, sintering the preform to form a sintered preform, and infiltrating the preform with at least one metal to form the article. At least one layer of the plurality of layers is formed from a beryllium-containing composition including beryllium powder. The infiltrating metal can be selected from aluminum and magnesium.
Claims19
