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

Autor: Pavlo E. Markovsky, Jacek Janiszewski, Olexander Dekhtyar, Matthew Mecklenburg, Sergey V. Prikhodko

Publikováno v: Crystals, Vol 12, Iss 5, p 645 (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. High-strain compression was con

Mechanical Energy Absorption Ability of Titanium-Based Porous Structures Produced by Various Powder Metallurgy Approaches

Autor: Pavlo E. Markovsky, Jacek Janiszewski, Oleksandr O. Stasiuk, Dmytro G. Savvakin, Denys V. Oryshych, Piotr Dziewit

Publikováno v: Materials; Volume 16; Issue 9; Pages: 3530

Porous materials are very efficient in absorbing mechanical energy, for instance, in combined armor, in order to improve the anti-ballistic protection characteristics. In the present study, porous titanium-based structures were manufactured via three
