Application of the Plasticity Characteristic Determined by the Indentation Technique for Evaluation Mechanical

摘要

The equilibrium between solid and liquid phases in sintered composite materials has been studied. It is shown that closed surfaces, which bound dispersed phases, influence the mechanical equilibrium between these phases. An expression is derived for a dihedral angle in composite materials, which includes values of surface tensions at the phase interfaces as well as parameters of a composite equilibrium structure (phase composition, particle contiguity and coefficietns of a particle geometry).
