The influence of Y content on grain structure evolution in Mg-Y alloys
Qianying Shi, Vaidehi Menon, Liang Qi +1
To advance the understanding of microstructural evolution behavior in Mg-rare earth alloys, the effect of yttrium (Y) addition on static recrystallization and grain growth in Mg al…
Strain-Rate- and Line-Length-Dependent Screw Dislocation Glide Mechanisms in BCC Refractory Metals and Alloys
Subhendu Chakraborty, Liang Qi
Plastic flow in body-centered cubic (BCC) metals and dilute/concentrated alloys is governed by the motion of <111> screw dislocations, whose glide is often impeded by cross-kinks (…
Visualizing metal-mediated nucleation and growth of GaN
Abby Liu, Zhucong Xi, Xiaobo Chen +6
Understanding the atomic-scale mechanisms governing metal-mediated nucleation and growth of gallium nitride (GaN) and related alloys is critical for tailoring their structural and…
The role of the solid-melt interface in accelerating the self-catalyzed growth kinetics of III-V semiconductors
Zhucong Xi, Abby Liu, Xiaobo Chen +5
Solid-melt interfaces play a pivotal role in governing crystal growth and metal-mediated epitaxy of gallium nitride (GaN) and other semiconductor materials. Using atomistic simulat…
Multiscale Modeling of Vacancy-Cluster Interactions and Solute Clustering Kinetics in Multicomponent Alloys
Zhucong Xi, Louis G. Hector, Amit Misra +1
Prediction of solute clustering kinetics in aged multicomponent alloys requires a quantitative understanding of complex vacancy-cluster interactions across multiple scales. Here, w…
