Abstract:Taking Au-Cu system as an example and being guided by systematoic science philosophy, the following contents are introduced: the alloy gene (AG) sequences and Gibbs energy transmission function of AG-holographic information; equilibrium and subequilibrium transmission models on disordering AuCuI( ) compound; the equilibrium holographic network phase diagrams (HNP) of Au₃Cu-, AuCu- and AuCu₃-type sublattice systems.The buleprints to predicate holographic information for designing advanced alloys are the equilibrium and subequilibrium HNP-diagrams of Au-Cu system, which describe the relationshipsamong component, composition, structure, properties and temperature. The road algorithms to realize network, information and intelligence designing advanced alloys are that “basic component system—AG-sequences—equilibrium HNP-diagrams of sublattice systems—equilibrium and subequilibrium HNP-diagrams of alloy system—AG-engineering—holographic knowledge and database”, which is called as the holographic alloy positioning design system (HAPDS).

Key words:Au-Cu system; alloy gene sequences; equilibrium and subequilibrium holographic network phase diagrams; holographic alloy positioning design system; systematic metal materials science
