Study of Structural and Mechanical Properties of Zr-, Ti- and La-based bulk Metallic Glasses, Ph.D. Dissertation Sharif University of Technology ; Aashuri, Hossein (Supervisor) ; Tavakoli, Rouhollah (Supervisor)
Abstract
Bulk metallic glasses (BMGs), in contrast to conventional crystalline materials, are defined as metals with an amorphous and disordered atomic-scale structure. Due to the absence of dislocations and grain boundaries, BMGs have considerably unique mechanical properties such as high strength and elastic strain, high wear resistance and desirable corrosion resistance. However, they generally suffer from poor plasticity caused by an inhomogeneous deformation which leads to catastrophic failure by localization of strain into narrow regions, known as shear bands. This factor has extremely restricted their application as advanced structural materials. Furthermore, the recently discovered phenomenon...
