| Abstract Scope |
We will discuss the potential of different X-Ray techniques helping to develop a deeper understanding of the unconventional modality of deformation through highly localized shear bands, resulting in macroscopic brittleness which leads to catastrophic failure.
The solidification of Zr- and Pd- based BMGs under gravity and micro-gravity conditions [1] has been studied by means of different X-ray techniques like diffraction and total scattering after processing. We obtained results on atomic pair-pair correlation functions that are about the local structure of the system, which allowed us to estimate the bond length, the average coordination number, and the free volume, a parameter that corre-lates the structure and properties of BMGs, such as the glass-forming ability and me-chanical properties.
