ABSTRACT:
A method of forming bulk metallic glass engineering materials, and more particularly a method for forming coarsening microstructures within said engineering materials is provided. Specifically, the method forms ‘designed composites’ by introducing ‘soft’ elastic/plastic inhomogeneities in a metallic glass matrix to initiate local shear banding around the inhomogeneity, and matching of microstructural length scales (for example, L and S) to the characteristic length scale RP(for plastic shielding of an opening crack tip) to limit shear band extension, suppress shear band opening, and avoid crack development.
