Unveil the brittle-flexible transition mechanism of partially dealloyed Ni-Zr-Ti metallic glasses
Source abstract
Abstract
This work designs Ni 40Zr 60-xTi x (x = 0, 20, 40, 60 at%) metallic glass (MG) ribbons as dealloying precursors and demonstrates that the hydrogen released during the dealloying process could be one of main factors that leads to the high fragility of nanoporous metals (NPMs). Moreover, it is firstly discovered that the surface cracks and the flexibility of dealloyed MG ribbons are highly dependence of the diffusivity of hydrogen atoms into the MG matrixes and the affinity of constituent elements to H element. Since dealloying often company with hydrogen release, the new finding is universal for the majority dealloying system.
