The Experimental And Theoretical Study Of Plasticity Improvement Of Zr-Based Bulk Metallic Glasses, Xie Xie

Doctoral Dissertations

Bulk metallic glasses (BMGs) attract more and more attention for their great mechanical properties, such as high strength, good corrosion resistance, etc. However, even though extensive studies have been made, their deformation mechanisms are still not well understood. Their limited plasticity and catastrophic failure after yielding severely prevent their broad applications in industry and daily life. To improve their plasticity, some work has been done through miscellaneous processing methods, e.g., thin-film coating, surface treatment, and ion irradiation. The present work also focuses on the plastic deformation of BMGs, and is expected to deepen the fundamental understanding of the deformation mechanisms …
