A phenomenological model of deformation twinning kinetics
(Peer reviewed; Journal article, 2021)Inspired by the classical Olson and Cohen model for martensitic phase transformations, a simple phenomenological model of the deformation twinning kinetics is proposed with account for twin-twin interactions. The model was ... -
A phenomenological model of twinning-mediated strain hardening
(Peer reviewed; Journal article, 2020)We present a model of strain-hardening in materials with twinning-mediated plasticity. While the model is largely phenomenological, it was motivated by microstructural considerations and can be claimed to be physically ... -
Plasticity in cryogenic brittle fracture of ferritic steels: Dislocation versus twinning
(Journal article; Peer reviewed, 2019)The sub-surface deformation structure after cryogenic (77 K) brittle fracture in a ferritic steel was characterized by scanning electron microscopy (SEM). Twin-like structures were found in many grains below the fracture ... -
Probing hydrogen effect on nanomechanical properties of X65 pipeline steel using in-situ electrochemical nanoindentation
(Peer reviewed; Journal article, 2021)The hydrogen effect on a X65 carbon steel was investigated using in-situ electrochemical nanoindentation approach. The alterations in elastic behavior, pop-in load, and hardness under hydrogen-free and hydrogen-charged ... -
The processing route towards outstanding performance of the severely deformed Al–Mg–Mn-Sc-Zr alloy
(Journal article, 2021)Aiming at obtaining the enhanced mechanical properties profile for lightweight applications, bulk billets of the commercial 1570C aluminium alloy (Al–5Mg-0.18Mn-0.20Sc-0.08Zr, wt. %) with nanosized aluminides of transition ... -
Structure, Texture and Strength of Mg-5.8Zn-0.65Zr Alloy after Hot-to-Warm Multi-Step Isothermal Forging and Isothermal Rolling to Large Strains
(Journal article; Peer reviewed, 2018)Aiming at improving deformability of wrought Mg alloys, the commercial hot-pressed alloy MA14 (ZK60) was subjected to hot/warm severe plastic deformation (SPD) to a total true strain of 9. The processing schedule involved ... -
Tensile characterization of a lead alloy: creep induced strain rate sensitivity
(Journal article; Peer reviewed, 2018)The aim of this work is to investigate and define the tensile properties of cable sheathing lead alloy. In particular its strain rate sensitivity due to the pronounced creep already present at room temperature, in relation ...
