Quantitative study of superplastic deformation mechanism of 5A90 Al-Li alloy

Cailiao gongcheng, 2019
The contribution of grain boundary sliding(GBS) and intragranular dislocation slip(IDS) in the 5A90 Al-Li alloy during superplastic deformation at 480℃ and an initial strain rate of 1×10-3s-1 was quantitatively investigated by analyzing the deformation ...

Thermophysical Investigation of Asteroid Surfaces. II. Factors Influencing Grain Size

The Planetary Science Journal, 2022
Asteroid surfaces are subjected to mechanical weathering processes that result in the development and evolution of regolith. Two proposed mechanisms—impact bombardment and thermal fatigue—have been proposed as viable and dominant weathering processes ...
