| Abstract | Particle reinforced aluminum matrix composites (PRAMCs) have the advantages of high specific strength and high specific modulus, and are important engineering materials for aerospace field. However, due to the huge difference in the mechanical properties between the reinforcements and the aluminum matrixes, the plastic forming of PRAMCs is quite difficult, which restricts their wide engineering applications. In order to improve the quality of plastic processing, it is necessary to optimize deformation parameters of PRAMCs. In this study, the hot deformation parameters of a 15%SiC/2009Al composite fabricated by powder metallurgy were optimized using a simulation method. Firstly, true stress-strain curves of the SiC/2009Al composite were obtained through hot compression tests, and then the strain rate sensitivity index (m) map at the ultimate strain was established. Under the deformation parameters corresponding to various m values, the finite element simulation of the hot compression process was carried out. The flow stress, strain and damage coefficient distribution of the hot-compressed samples were analyzed. The results show that it is reliable to use the m value as the basis for optimizing the processing parameters, which were further verified by the microstructural observations. The deformation temperature and strain rate corresponding to the optimum parameters of the composite were determined to be 500 and 0.01 s(-1), respectively. |
