The resistivity recovery of dilute alloys of silver, copper, and gold, proton irradiated at 80°K
… order. The recovery of the silver and copper alloys showed remarkable similarity to pure silver and copper, but the gold alloy's recovery was markedly altered as compared to pure gold. Activation energies for the stage III defect in silver, copper and gold were found to be ,64, .71 and ,70ev …

Rare earth impurities in metals: The transition from virtual to bound f levels
… magnetic susceptibility have been carried out in dilute alloys of the rare earth metals in liquid Cu. Other measurements of the Al and Cu Knight shift in dilute alloys of Gd in Al-Cu and Al-Ag binary alloys have also been made. The susceptibility measurements of the rare earths in liquid Cu …

Magnetic susceptibility and knight shift measurements in aluminum-rare earth alloys
… susceptibility and solvent Knight shift in dilute alloys of rare earth metals in aluminum have been carried out. The susceptibility results give a clear indication that localized moments exist on each impurity except La, Yb, and Lu, and that the coupling between the total spin and The total …

Anisotropy effects in the critical field of superconducting tin-indium alloys
… curve, Hc versus T, for eight superconducting dilute alloys of indium in tin near the critical temperature and at low temperatures extending to about 0.30 K. The effective magnitude of the superconducting energy gap is sensitive to the direction of the electron momentum relative to the crystal …

Percolation phenomena in amorphous iron-nickel alloys
… fields, are reported for the series of amorphous alloys (FepNi1_p)80P20. The iron-rich alloys are shown to be good ferromagnets, with the expected ferromagnetic critical behavior. Nickel, however, serves as a paramagnetic diluent. The amorphous structure permits the production of alloys that span …

Interstitial-impurity trapping in Al-Fe and Al-Zn
… electron irradiation near 65K of A1-Fe and A1-Zn dilute alloys. Multiple relaxation processes were observed in both alloys. In the case of A1-Zn, the simultaneous annealing near 130K of resistivity, diae1astic modulus changes, and a parae1astic relaxation peak in C' allows for a characterization …

Design Strategies for Improving the Oxidation Resistance of Multi-Principal Element Alloys
Since the early 1940’s, nickel-based superalloys (SA) have been the cornerstone of hightemperature structural alloys due to their unique yield strength, creep life, and oxidation re-sistance when subject to harsh environments exceeding 1000 °C. While they have withstoodthe increasing operation …
