摘要：

This paper presents the results of an in situ study of crack nucleation and growth in an in situ TiBw/Ti composite. The crack/microstructure interactions are studied along with the underlying crack-tip shielding by crack bridging and whisker pull-out. The reinforcement/matrix interface is also shown to retard crack growth. Final fracture is shown to occur by quasi-cleavage fracture mode. (C) 2004 Published by Elsevier B.V.
