摘要：

At least four distinct separation fracture modes (mechanisms) have been proposed for the fracture of SiC-Al composites: firstly, cracking of the SiC particles or whiskers in front of an advancing crack tip and the linking of these cracks; secondly, SiC particles or whiskers cracking and this crack initiating a fracture; thirdly, void nucleation and growth at the interfaces of SiC particles or whiskers and the matrix; fourthly, fracture of the matrix. There is evidence which supports all these mechanisms, and conversely there are data which indicate that these mechanisms have no relationship to the actual fracture process. It was found that the mode of fracture is through the matrix.
