Abstract: A mathematical model of hot isostatic pressing (HIP) densification was set up upon HIP densification theory. The model was realized through computer simulation, and the computer calculation, drawing, analysis of HIP map were accomplished. The HIP map of 3Y-TZP was tested by experiments and the results of experiments cohered well with those of theoretic calculation. The optimization of HIP procedure parameters was discussed through HIP maps.

Key words: hot isostatic pressing, densification, mathematical model, computer simulation, TZP ceramics
