Obstacles, such as voids and precipitates, are prevalent in crystalline materials. They
strengthen crystals by serving as barriers to dislocation glide. In this work, we develop a …

In the present work, the effect of a pre-existing nanovoid on martensitic phase transformation
(PT) is investigated using the phase field approach. The nanovoid is created as a solution of …

Atomistic simulation methods are appropriate tools for investigating the dynamics of
dislocations and their interactions with obstacles in metallic materials. In particular …

The vast majority of our current knowledge regarding the basic mechanisms controlling
irradiation effect on mechanical properties is based almost entirely on the results of post …

The introduction of obstacles (eg, precipitates) for controlling dislocation motion in molecular
structures is a prevalent method for designing the mechanical strength of metals. Owing to …

The strengthening of metals by nano-scale obstacles is mainly attributed to the impediment
to glide dislocations offered by these obstacles. It is important to understand the …
