and Engineering, Nanjing University of Technology, Nanjing 210009, China) Abstract: To understand the high strain rate deformation mechanism and determine the grain size, strain rate and porosity dependent yield strength of nanocrystalline materials, a new mechanical model based on the deformation mechanism of nanocrystalline materials under high strain rate loading was developed. As a first step......

out that this material shows superplasticity with the elongation of 595% in the external tensile process parameters of 900 °C and 0.001 s-1, which suggests that superplastic deformation happens in this process parameter configuration. It is well known that superplastic deformation is a stable deformation. The above results obtained via metallographic observation are consistent with those......
