Bulk Metallic Glass Composite

In this work, a small amount of Nb has been added in a Zr52Cu42.5Al5.5 bulk metallic glass, and a Zr52Cu42Al5.5Nb0.5 bulk metallic glass composite with dual-amorphous and nanocrystal structures has been developed for the first time. This in situ formed bulk metallic glass composite has a larger room compressive plasticity of above 13% than that of the Zr52Cu42.5Al5.5 bulk metallic glass. The excellent plasticity of the bulk metallic glass composite is attributed to the phase-separated matrix with micro-nanocrystal and the nanocrystallization during the deforming process. This work may give a new sight into design bulk metallic glass composites and the underlying mechanism for deformation.

Bulk Metallic Glass Composite

The compressive deformation behaviors and microstructures of Cu45Zr48Al4Nb3 bulk metallic glass composites with diameters of 3, 2, and 1 mm were investigated systematically. It was found that the smallest sample showed the highest yield strength and compressive plasticity. The yield strength of the samples was found to depend on the fraction of their crystalline phases in the glassy matrix. The smaller samples showed larger free volumes, which is favorable for plastic deformation. The deformation behavior of the samples was found to depend on their size. The results obtained in this study will be helpful for investigating the mechanical behavior of metallic glass composites.

Nanoscale dimples and periodic corrugations are observed on the fracture surface of Zr-based bulk metallic glass composite (BMGC). The nanoscale periodic corrugations display a curved shape, which is different from that observed in previous works. In addition, the crystallization behavior of [Formula: see text][Formula: see text][Formula: see text][Formula: see text] BMG was investigated. The second crystallization event of Zr-Cu-Ni-Al BMG can be controlled by annealing or tuning cooling rate. The in situ Zr-based BMGC was prepared via lowering cooling rate. The Zr-based BMGC displays completely brittleness.
