Deformation Mechanism and Structural Changes in the Globular Ti-6Al-4V Alloy under Quasi-Static and Dynamic Compression: To the Question of the Controlling Phase in the Deformation of α+β Titanium Alloys

Crystals, 2022
The deformation mechanism of the Ti-6Al-4V (wt.%) alloy with globular structure was studied under conditions of quasi-static and high-strain compression with rates 10−3 s−1 and 2.1–3.3 × 103 s−1, respectively.

The origin of compression influences geometric instabilities in bilayers [PDF]

, 2018
Geometric instabilities in bilayered structures control the surface morphology in a wide range of biological and technical systems. Depending on the application, different mechanisms induce compressive stresses in the bilayer.

Tension-compression asymmetry of an AM magnesium alloy unveiled by in-situ synchrotron X-ray diffraction

Journal of Magnesium and Alloys
Magnesium (Mg) alloys typically exhibit anisotropic mechanical behaviors due to their hexagonal close-packed (hcp) crystal structures, often leading to tension-compression asymmetries.

Effect of unusual texture on tension-compression asymmetry for Mg-RE alloy by viscoplastic self-consistent modeling

Journal of Magnesium and Alloys
The tension-compression asymmetry presents notable challenges for the application of magnesium alloys in many fields. In this study, the solid-solution treated Mg-8.5Gd-4.5Y-0.8Zn-0.4Zr alloy's tension-compression asymmetry was examined using optical ...
