  • Method for making high ductility beryllium bodies
    Patent number: 3999986
    Abstract: A method for making high ductility beryllium bodies by controlling beryllium oxide particle growth during hot pressing of beryllium powder to a maximum median size of 150 nm. More particularly, particle size is controlled by utilizing starting beryllium powder containing a maximum total concentration of aluminum, silicon and magnesium of 200 ppm and consolidating the powder at a maximum temperature of 1400.degree. F. Ductility is also enhanced by utilizing starting beryllium powder containing a maximum beryllium oxide volume fraction of 1.6 percent and annealing the consolidated powder at temperatures of from 2000.degree. to 2250.degree. F. The anneal can be a separate operation or a continuation of the hot pressing operation.
