- Summary
- Au--Ge alloys of compositions 6 to 95 at.% Ge were rapidly quenched to room temperature and the various phases studied. A fcc phase was formed at low Ge compositions (8 to 20 at.%), and its constant lattice parameter (4.0818 plus or minus 8 A) indicated that rapid quenching did not affect the solubility of Ge in Au. A hcp phase was formed in alloys of 10 to 30 at.% Ge, and in addition in alloys of >56 at. % Ge. The latiice parameters of the hcp phase are a = 2.844 plus or minus 2 and c =4.748 plus or minus 5. Still another nonequilibrium phase of unknown structure was formed in alloys of 15 to 60 at.% Ge; its large d'' spacings indicate that its unit cell contains a large number of atoms. Quenching experiments to liquid N/sub 2/ temperatures failed to reveal amorphous phases. (D.L.C.)
