Abstract
The paper presents the results of a combined experimental and analytical st udy of transformation toughening in NiAl composites reinforced with 20 vol. % of 2 mole % yttria stabilized zirconia particles. The extent of stress-i nduced phase transformation is characterized using laser Raman spectroscopy techniques. The overall toughening increment due to stress-induced transfo rmation is also predicted using micromechanics models that account for the role of dilatation only, or the combined effects of dilatation and shear.
