Self-adaptive dislocation morphing ductilizes a refractory high-entropy alloy across an ultrawide temperature spectrum

Xichen Zhou, Qianyong Zhu, Hongliang Dong, Xiao Liang et autres

Metals usually fracture catastrophically at cryogenic temperatures and soften rapidly at high temperatures. This dilemma arises from the incompatibility of strengthening mechanisms across vast temperature regimes. Here, this work unveils a self-adaptive dislocation morphing mechanism in a model NbTaTi-based refractory high-entropy alloy …

Correlating microstructure recovery to rejuvenation of high-temperature creep properties in a crept single-crystal superalloy

Yunpeng Hu, Yi Hong Ru, Xichen Zhou, Boxuan Du et autres

Academic debate still exists as to whether and how multi-scale microstructure recovery is linked to creep properties rejuvenation of superalloys. We propose a rejuvenation heat treatment (RHT) for one single-crystal superalloy crept at 1100 °C/120 MPa, by which the degraded phase- and …

Design of Driving Waveform Based on Overdriving Voltage for Shortening Response Time in Electrowetting Displays

Wenjun Zeng, Zichuan Yi, Yiming Zhao, Weibo Zeng et autres

A fast response speed of a pixel is important for electrowetting displays (EWDs). However, traditional driving waveforms of EWDs have the disadvantage of long response time. So, a driving waveform, which based on overdriving voltages and charge trapping theory, was proposed in …
