Dislocation strengthening plays a constructive role in exploring the improvement of
mechanical properties of deformed aluminum matrix composites. However, theories about …

In this study, we proposed a method, which is a combination of qualitative analysis and
quantitative analysis, to establish dislocation-based plasticity model, and assessed the time …

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 …

Slip intermittency and stress oscillations in titanium alloy Ti–7Al–O that were observed using
in-situ far-field high energy X-ray diffraction microscopy (ff-HEDM) are investigated using a …

In this work, microstructural changes during creep of Ni-based alloy 617 at 700° C and 165
MPa have been investigated by electron microscopy, and complementarily modelled …

This paper extends the two time-scale modified phase-field crystal model to examine crystal
plasticity. Two non-linear density dependent functions are constructed to effectively …

Multi-principal element alloys (MPEAs) exhibit outstanding strength attributed to the complex
dislocation dynamics as compared to conventional alloys. Here, we develop an atomic …

An aluminum matrix composite with dispersed carbon nanotubes (CNTs) was produced via
flake powder metallurgy using a micro-rolling process and vacuum hot pressing (VHP) …

Although researchers have extensively investigated the dynamic mechanical properties of
metallic materials at the macro-scale in terms of deformation mechanisms, strain rate …

Brittle fracture and ductile failure are critical events for any structural or functional
component, as it marks the end of lifetime and potential hazard to human life. As such …
