摘要
Abstract
Two different size of Al-matrix composites with high volume fraction of SiC particles were produced with the new pressureless infiltration fabrication technology. The phase composition, microstructure and fracture morphology of the composite were analyzed by XRD and SEM. The results show that the SiCp/Al composite has homogeneous organization and high density without any pore and inclusion. The reaction products in the interface are composed of Mg2Si, SiO2 and Si. The composite has compressive strength of 500 MPa, and display a brittle characteristic at fracture.关键词
