Abstract: Taking experimental path on disordering AuCuI) ( Cu4

4A stem alloy genes as an example, three discoveries and a method were presented. The ability of AuCuI) ( Cu4 Au 8 AA to keep structure stabilization against changing temperature is attributed to the fact that the Au8A and Cu 4A potential well depths greatly surpass their vibration energies, which leads to the subequilibrium of experimental path. A new atom movement mechanism of AuCuI) ( Cu4 Au 8 AA to change structure for suiting variation in temperature is the resonance activating-synchro alternating of alloy genes, which leads to heterogeneous and successive subequilibrium transitions. There exists jumping order degree, which leads to the existence of jumping Tj-temperature and an unexpected so-called “retro-effect ” about jumping temperature retrograde shift to lower temperatures upon the increasing heating rate. A set of subequilibrium holographic network path charts were obtained by the experimental mixed enthalpy path method. Key words: intermetallics; alloy gene; order/disorder transformation; resonance activating−synchro alternating mechanism; thermodynamic properties; equilibrium and subequilibrium holographic network path chart
