Heterogeneous Microstructure and Tensile Properties of FeMnCoCr Metastable High-Entropy Alloy.

Face-centered cubic (FCC)-structured high-entropy alloys (HEAs) are facing a major challenge due to a trade-off between strength and ductility. In this paper, we systematically investigated the microstructural evolution and tensile properties of metastable dual-phase (DP) FeMnCoCr HEAs via cold rolling and partial recrystallized annealing, which resulted in a heterogeneous microstructure, and by inducing strengthening and strain-hardening through heterogeneous deformation-induced (HDI) strategies. The results show that the alloy was annealed at 600 °C for 10 min, exhibiting a good combination of strength and ductility.

Quantitative EEG and its relationship with attentional control in patients with anxiety disorders.

Alterations of interhemispheric functional homotopic connectivity and corpus callosum microstructure in bulimia nervosa.

Background: Accumulating evidence indicates maladaptive neural information interactions between different brain regions underlie bulimia nervosa (BN). However, little is known about the alterations in interhemispheric communication of BN, which is facilitated by the corpus callosum (CC), the major commissural fiber connecting the two hemispheres. To shed light on the interhemispheric communications in BN, the present study aims to explore alterations of interhemispheric homotopic functional connectivity and the CC microstructure in BN.
