摘要：
An aluminum alloy composite reinforced with chopped Al2O3 fibers randomly oriented in a plane has been produced by a modified squeeze casting process and its mechanical behavior compared with the corresponding behavior of the matrix. The specific characteristics of the compositing process have been examined vis-à-vis the characteristics of liquid metal infiltration into the capillaries of the fiber bundle. The flow stresses in the as-cast composite have been correlated with predictions based on continuum plasticity. Fracture of the fibers has also been characterized and interpreted using a weakest link statistical model, in conjunction with trends in the stress in the fibers. Changes in the composite flow stress caused by such fractures have been addressed. Finally, residual stress effects have been analyzed. © 1990.
