Metastable alloys of beryllium prepared by ion implantation

Surface alloys of beryllium metal have been prepared by high-fluence ion implantation of Ag, Ti, Zn, and Cu with solute concentrations ranging from a few tenths of a percent to tens of percent. Resulting surface layers were analyzed using the Rutherford backscattering/channeling technique and glancing angle X-ray diffraction methods. Solute depth profiles, lattice location, and precipitation behavior were derived and solvent lattice damage and recovery were studied as a function of fluence and annealing temperature.
