The dispersion strengthened copper alloy was attracted as thermal and electrical functional material for the high mechanical strength, high thermal stability and good conductivity of . In the present study, the focus is on the synthesis of dispersed copper alloy by spark plasma sintering process using copper oxide and titanium diboride as raw materials. The mechanical, thermal and electrical properties of sintered bodies were discussed with the sintering parameters, and developed microstructure and phase of sintered bodies.

A theoretical model is applied to the analysis of thermomechanical properties of FGMs in this study. Functionally graded composites ( FGMs) consisted with 10 layers gradually changing volume fractions of Al and were fabricated using the pressureless infiltration technique. FGMs plates of total thickness of 3mm, 5mm and 7mm with fairly uniform distribution and compositional gradient of reinforcement in the Al matrix throughout the thickness was successfully fabricated. The curvature of FGM plates was measured to check the internal stress distribution predicted via a theoretical model for the analysis of thermo-mechanical deformation. The evolution of curvature and also internal stresses in response to temperature variations could be predicted for the different combinations of geometric thickness of FGM plates. Theoretical prediction of thermally induced stress distribution makes it possible to design FGM structures without any critical failure during the usage of them.
