    摘要: 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.

    摘要: Sheet casting of metallic glasses and twin roll sheet casting of bulk metallic glasses and composite in an inert environment. Samples may be heated by RF to a temperature in the semi-solid region. After semi-solid processing, the partial liquid then may be poured or injected to achieve the desired shape. Plates of metallic glasses and/or metallic glass matrix composites may be formed (for example, through diecasting) and serve as a pre-form for rolling. In this configuration, the plates may be lowered through a radio frequency coil into compressing wheels, directly next to or below the coil. As the plates pass through the coil they may heat to above the glass transition temperature. Next, they may be fed into the rolling wheel to thermoplasically form the plates into thinner sheets.
