Simultaneously utilized nanodomains and a fine-grain effect to improve the energy storage properties in BaTiO<sub>3</sub>-based ceramics<italic>via</italic>core–shell structural design.
AbstractDesigning the fine-grained ceramics with high recoverable energy storage density and excellent mechanical performance, still presents great challenges. Because large pore size low relative were obtained by traditional sintering method, they always exhibit small breakdown strength poor properties, which limits miniaturization operation of devices in harsh environments. In this article, we designed barium titanate (BT) grain 252 nm 0.92 can be via co-sintering two sizes BT particles at...
The micro-nano BaTiO3 ceramics of different sizes have been prepared simply and controllably via a self-assembly sintering method. Through giving the size powders combination way, binary particle method can synthesize with grain sizes. When ternary quaternary is used to ceramics, relative density be increased, but controllability has reduced. Therefore, use beneficial controllably.
An experimental study on superplastic forming behaviors and microstructure characters of commercial magnesium alloy sheet AZ31B is presented in this paper. The main results show that the has capability. For received without any pre-processing, maximum elongation 295%. dynamic recrystallization grain refinement can be found, In case temperature <350°C, growth appears if ≥ 350°C. improved by controlling refinement. Some free bulging are influence capability much less than influences...
The microstructure evolution and mechanical properties of magnesium alloy AZ31D processed by equal channel angular extrusion(ECAE) are studied. processing temperature the passes extrusion important factors to affect during ECAE. In this paper, ECAE was performed at from 523 673K. ductility increased through grain refinement after because recrystallization took place high angle boundary formed. elongation alloys improved maximum elongation-to-failure for 4 573K strain rate 0.5 10−4 s−1 × 350%.
The micro-nanoBaTiO 3 ceramics of different sizes have been prepared simply and controllably via a self-assembly sintering method. effects scopes the application this method in controllable synthesis are investigated. Through given size BaTiO powders combination way, with grain sizes, such as 400~500 nm, can be synthesized. Therefore, use is conducive to realization ceramics.
