Based on principles of thermodynamics, it is derivd that in binary system the quasi-parabola regulation must be obeyedby the standard Gibbs free energy of formation of a compound.Extending to ternary system a quasi-paraboloid regulation also must be done. The stability of some intermetallic compounds in binary systems is decided

A model Cu-AlN composite has been prepared by ion implantation technique and annealing. The atomic configuration and lattice relationship of a low-energy inherent interface(11)Cn//(0001)AlN were studied by using transmission electron microscopy and geometrical modelling. By analysing the dichromatic pattern of the composite,a primary structural unit of the interface atomic configuration was determined for purpose of HREM image simulations and of studying the structurul relaxation state in the near-interface region.

After deformed and annealed, 70Cu-30Ni alloy with irrecrystallization or incomplete recrystallization mainly consisting of deformed grains displayed unstable E.(corrosion potential) and low Rp (polarization resistance) in 3.5%NaCl, and corrosion product film contained a lot of seawater species in the outer layer and denickelified in the inner layer immersed in seawater for 3 and 6 months, and intergranular corrosion occurred in the matrix. With the increase of deformation and annealing temperature, the anodic oxide film formed by polarization in artificial seawater was increasingly stable. The recrystallized alloy was stable in Ec and high in Rp and its corrosion product film formed in seawater was uniform and rich in Ni.
