Deformation-Induced Solid-State Amorphization in a Nanostructured Al-Mg Alloy Processed by High Pressure Torsion

Autor: Hans Jørgen Roven, Zhen Ya Zhang, Xue-feng Xie, Manping Liu, Hui Wang

Publikováno v: Materials Science Forum. 817:627-633

This work reports the experimental evidence of localized solid-state amorphization (SSA) in a nanostructured Al–Mg alloy processed by high pressure torsion at room temperature. Electron backscatter diffraction analysis indicated that the deformed a

Velocity-Toughening and Crack Speed Oscillations in the Dynamic Fracture of PMMA Plates

Autor: Zhong Duan, Zhen Ya Zhang, Feng Hua Zhou

Publikováno v: Applied Mechanics and Materials. 566:298-304

To study the propagating behavior of a dynamic crack in brittle materials, an experimental technique was developed that measures the propagation speed of a fast crack in a preloaded brittle strip. The specimen is a rectangular PMMA plate clamped by t
