HIPING CONDITIONS FOR PROCESSING OF METAL MATRIX COMPOSITES USING THE CONTINUUM THEORY FOR SINTERING--I. THEORETICAL ANALYSIS

摘要

The model of hot isostatic pressing fibre-reinforced metal matrix composites is elaborated. On the basis of the rheological relationships obtained, taking into consideration the structural anisotropy and large void imperfections, the kinetics of porosity and imperfection parameters' evolution are analysed. The algorithm of the calculation for the distribution of micro-stresses and deformations around fibres, is elaborated for the cases of one- and two-layers fibre coatings.
