Understanding the hydrogen effect on pop-in behavior of an equiatomic high-entropy alloy during in-situ nanoindentation
(Peer reviewed; Journal article, 2021)The variations in the pop-in behavior of an equiatomic CoCrFeMnNi high-entropy alloy under different hydrogen charging/discharging conditions were characterized via in-situ electrochemical nanoindentation. Results show ... -
Nanomechanical Characteristics of Trapped Oil Droplets with Nanoparticles: A Molecular Dynamics Simulation
(Peer reviewed; Journal article, 2021)Nanoparticles (NPs) possess great potentials in applications to enhanced oil recovery (EOR), the underlying mechanisms of which however remain to be explored. In this study, the motion of NPs and the local pressure ... -
Microstructure and nanomechanical behavior of an additively manufactured (CrCoNiFe)94Ti2Al4 high-entropy alloy
(Peer reviewed; Journal article, 2021)Recent substantial studies indicate that high-entropy alloys (HEAs) possess superior mechanical performance, including exceptional strength, high creep resistance, etc. However, additive manufacturing (AM), a burgeoning ... -
Experimental and numerical study of notched SHS made of different S355 steels
(Peer reviewed; Journal article, 2021)This study compares the mechanical behaviour of square hollow sections (SHS) made of three different types of S355: cold-formed, hot-rolled and offshore steel. A material model and failure criterion for each steel type ... -
Hydrogen-induced transgranular to intergranular fracture transition in bi-crystalline Nickel
(Peer reviewed; Journal article, 2021)It is known that hydrogen can influence the dislocation plasticity and fracture mode transition of metallic materials, however, the nanoscale interaction mechanism between hydrogen and grain boundary largely remains illusive. ... -
