Abstract
Fracture and fatigue crack growth properties of coarse scale Nb/Nb3Al laminated composites are examined, and their performance is contrasted with similarly reinforced in situ particulate and microlaminate compo sites. It is found that laminate orientation has a larger effect on fa tigue crack growth resistance than on fracture toughness; properties a re optimal in the crack arrester as compared with the crack divider or ientation. In addition, thicker Nb layers yield improved fracture and fatigue crack growth properties; and the effect is more prominent in t he divider orientation. Mechanisms underlying this behavior are briefl y described. (C) 1997 Elsevier Science S.A.
