Superplastic Deformation of TC6 Alloy
Journal of Aeronautical Materials, 2016 The superplastic tensile tests of TC6 alloy were conducted in the temperature range of 800-900℃ by using the maximum m value superplasticity deformation (Max m SPD) method and the constant strain rate deformation method at the strain rate range of 0.0001-

Advanced Science, Volume 12, Issue 33, September 4, 2025.This study highlights the drastic influence hydrogen has on the microstructure evolution during severe plastic deformation. High‐pressure torsion of a TiVZrNbHf‐Cu composite results in mechanical alloying and subsequent amorphization, whereas replacing the high entropy alloy with the corresponding hydride stabilizes a two‐phase microstructure.

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.Abstract We analyze large‐scale shear zones that are exposed along the equatorial chasmata of Eastern Aphrodite Terra to understand the role of strain localization in the deformation of the Venusian crust. These shear zones dip at low angles opposite to the slopes, forming terraces that expose portions of the shear planes.

Superplasticity and anelasticity in fine-grained Sn-Pb alloys
, 1979 Mechanisms which may play a role in superplastic deformation (grain strain mechanisms, grain boundary sliding (GBS) mechanisms) are reviewed. Two well-known lattice dislocation mechanisms are re-evaluated for grain boundary dislocations (GBDs).

Effect of Heating Rate on Grain Structure and Superplasticity of 7B04 Aluminum Alloy Sheets
Cailiao gongcheng, 2017 Fine-grained 7B04 aluminum alloy sheets were manufactured through thermo-mechanical treatment. The effects of anneal heating rate on grain structure and superplasticity were investigated using electron back scattering diffraction(EBSD) and high ...

High Voltage, Volume 10, Issue 3, Page 673-679, June 2025.Abstract This study focuses on the distribution of high‐resistance media (pores and spinels) within ZnO $\text{ZnO}$ varistors and explores the mechanical and electrical failure mechanisms of varistors under different pulse actions. Micro‐CT technology revealed that the proportion of high‐resistance media in the edge area is much higher than in the ...
