mechanisms of interactions between the dislocation and TBs. Key words: twin boundary; twinning dislocation; slip transfer reaction; athermal process 1 Introduction Interaction between dislocation and grain... plasticity and plays an important role in the kinetic process of mechanical properties of materials. In hexagonal close-packed (hcp) metals, twinning is the dominant deformation mechanism due to the limited......
shows high hardness, brittle behavior, and poor ductility. Field emission scanning electron microscopy (FESEM) reveals round morphology of athermal ω (ωath) precipitates. The presence of ωath phase...-induced martensitic transformation. In addition, a new and very simple method was designed and used for shape memory effect measurement. Key words: Ti-Mo-Sn alloys; shape memory effect; athermal ω......

="ChDivSummary" name="ChDivSummary">The effects of electropulsing-assisted ultrasonic surface rolling process on surface mechanical properties and microstructure evolution of commercial pure titanium were investigated. It was found that the surface mechanical properties were significantly enhanced compared to traditional ultrasonic surface rolling process(USRP), leading to smaller surface roughness......
