Abstract

Deformation-induced phase transformation behavior is beneficial for plasticity and work hardening ability of bulk metallic glass composites (BMGCs). In this study, the effects of preloading treatment on the microstructure and dynamic mechanical properties of a TiZr-based BMGC with deformation-induced phase transformation were systematically studied. The strength and impact absorption energy of the composite were improved after the preloading treatment. Under a pressure of 1000 MPa for 10 min, the composite exhibits the best dynamic mechanical properties. The composite has an impact absorption energy of 18.7 MJ m⁻³, 10 times that of the as-cast sample. These results are attributed to the preformation of martensite during the preloading treatment and increases in volume fraction and variant types of martensite during the final dynamic deformation process. Deformation-induced phase transformation can effectively release local stress concentration, refine β phase grains, promote formation of multiple shear bands, and ultimately lead to a significant improvement in impact absorption energy. This study provides a new approach for improved dynamic mechanical properties of BMGCs.

期刊介绍： This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys. The journal reports the science and engineering of metallic materials in the following aspects: Theories and experiments which address the relationship between property and structure in all length scales. Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations. Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties. Technological applications resulting from the understanding of property-structure relationship in materials. Novel and cutting-edge results warranting rapid communication. The journal also publishes special issues on selected topics and overviews by invitation only.
