A new glass-forming ability criterion for bulk metallic glasses

High-strength Cu-based bulk glassy alloys in Cu-Zr-Ti and Cu-Hf-Ti ternary systems

Owing to a lack of microstructure, glassy materials are inherently strong but brittle, and often demonstrate extreme sensitivity
to flaws. Accordingly, their macroscopic failure is often not initiated by plastic yielding, and almost always terminated by brittle
fracture. Unlike conventional brittle glasses, metallic glasses are generally capable of limited plastic yielding by shear-band
sliding in the presence of a flaw, and thus exhibit toughness–strength relationships that lie between those of brittle ceramics
and marginally tough metals. Here, a bulk glassy palladium alloy is introduced, demonstrating an unusual capacity for shielding
an opening crack accommodated by an extensive shear-band sliding process, which promotes a fracture toughness comparable
to those of the toughest materials known. This result demonstrates that the combination of toughness and strength (that is,
damage tolerance) accessible to amorphous materials extends beyond the benchmark ranges established by the toughest and
strongest materials known, thereby pushing the envelope of damage tolerance accessible to a structural metal.

A damage-tolerant glass.

The mechanical properties of ex-situ and in-situ metallic glass matrix composites (MGMCs) have proven to be both scientifically unique and of potentially important for practical applications. However, the underlying deformation mechanisms remain to be studied. In this article, we review the development, fabrication, microstructures, and properties of MGMCs, including the room-temperature, cryogenic-temperature, and high-temperature mechanical properties upon quasi-static and dynamic loadings. In parallel, the deformation mechanisms are experimentally and theoretically explored. Moreover, the fatigue, corrosion, and wear behaviors of MGMCs are discussed. Finally, the potential applications and important unresolved issues are identified and discussed.
