摘要：

This paper presents preliminary experimental evidence of synergistic interactions between transformation toughening and crack bridging in an NiAl composite reinforced with 2 mol% yttria partially stabilized zirconia and molybdenum particles. The observed levels of synergy are shown to be consistent with predictions from a theoretical model by Amazigo and Budiansky (J.C. Amazigo, B. Budiansky, J. Mech. Phys. Solids 36 (1988) 581-595.). The implications of the results are also discussed for the potential development of synergistically toughened intermetallic and ceramic composites. (C) 1999 Elsevier Science S.A.
