Phase diagram of Au-Al-Cu at 500 °C

Submonolayer Au on Si(111) phase diagram

Based on a review of the current literature, a surface phase diagram is proposed for the submonolayer Au on Sit 111 ) system. Kinetic considerations are reviewed and key surface phase diagram features such as the O < 0.4 ML metastable Sit 11 l )-1~/3 x ~/3 tR30 Au structure and the high temperature Si(11 l )-(V3 x ~/3tR3q'-Au to Sil 1 l 1 )-( 1 x 1 tAu second order phase transition are discusse...

Cu-Au, Ag-Au, Cu-Ag, and Ni-Au intermetallics: First-principles study of temperature-composition phase diagrams and structures

The classic metallurgical systems—noble-metal alloys—that have formed the benchmark for various alloy theories are revisited. First-principles fully relaxed general-potential linearized augmented plane-wave ~LAPW! total energies of a few ordered structures are used as input to a mixed-space cluster expansion calculation to study the phase stability, thermodynamic properties, and bond lengths in...

THE ICOSAHEDRAL Al-Li-Cu PHASE

Systematics of Global Observables in Cu+Cu and Au+Au Collisions at RHIC Energies

Charged particles produced in Cu+Cu collisions at √ sNN = 200 and 62.4 GeV have been measured in the PHOBOS experiment at RHIC. The comparison of the results for Cu+Cu and Au+Au for the most central collisions at the same energy reveals that the particle density per nucleon participant pair and the extended longitudinal scaling behavior are similar in both systems. This implies that for the mos...

Phase Diagram of weakly pinned YBa 2 Cu 3 O 7 − δ for H ‖ c

Abstract — Vortex phase diagram in a weakly pinned crystal of YBCO for H ‖ c is reviewed in the light of a recent elucidation of the process of ‘inverse melting’ in a Bismuth cuprate system and the imaging of an interface between the ordered and the disordered regions across the peak effect in 2HNbSe2. In the given YBCO crystal, a clear distinction can be made between the second magnetization p...
