摘要

Process for the preparation of beryllium coated products and semi-finished products, characterized in that it comprises the combination of the successive steps of preparing a beryllium blank or roughing from a cast ingot, roughing lining with at least one layer of at least one layer a metal or plastic alloy, such as aluminum and its alloys, magnesium, zinc, antimony, mechanical transformation of the coated slab, especially by rolling, drawing, drawing, hammering, at a temperature below 620º C and, preferably, between 300 and 400º C , with a degree of cold beating or deformation at least equal to 50%, and preferably comprised between 50 and 100%, said method especially allowing to reduce the sensitivity of beryllium to the notching effect, to intercrystalline corrosion and to the easy diffusion of certain metallic or gaseous elements.
