Abstract
AbstractA variety of materials have been toughened by incorporating ductile phases. Brittle silicide intermetallics such as Nb5Si3 composited with niobium particles incorporated during in situ processing techniques have realized significant improvements in toughness and stable crack extension. In the present work, toughness tests conducted on Nb5Si3/Nb materials monitored in a scanning electron microscope were instrumental in viewing the role of the deforming niobium particles on the process of toughening. In particular, the behavior of the ductile phase was monitored and related to the toughness values obtained. In an attempt to vary the behavior of the ductile phase, the composite materials were exposed to a variety of gaseous environments and subsequently tested in air. The resulting toughness, resistance-curve behavior, and in situ test results highlight the importance of the behavior of the ductile phase on subsequent properties.
