Numerical Simulation on Thermal Shock Resistance of TiB2-Cu Interpenetrating Phase Composites
TiB2-Cu Interpenetrating phase composites (IPCs) were prepared by combustion synthesis of elemental titanium, boron and copper powders. The synthesized product consisted of two spatial continuous phases: TiB2 and copper. Using the experimental data, thermo-physical and mechanical parameters of the materials established the temperature and stress fields made of FEM. Thermal shock behavior of TiB2-Cu IPCs was also investigated using a plasma torch arc heater and the results showed no cracks were found on the thermal shock surface of the TiB2-Cu IPCs. The experimental and numerical modeling results can be used to explain the actual thermal shock resistance and reveal its complex behavior under the severe condition.
