Deformation twins (DTs) and stacking faults (SFs) are rarely found in Cu-20Ni-20Mn alloy, which limits further strengthening of alloy. Here, we report ultra-strong alloy prepared by introducing a high density coherent nanoprecipitates. The ultimate tensile strength (UTS) can be largely enhanced to 1624.7 ± 14.7 MPa, while maintaining an acceptable elongation 7.3 0.5%. We find that the nanoprecipitates contribute ultra-high true stress up about 1740 facilitate formation DTs. ductility...
The effects of Ag addition on the microstructure Sn–9Zn alloy and its corrosion behaviour in neutral static 3.5 wt% NaCl solutions were investigated using surface characterization techniques electrochemical techniques. results show that Sn–9Zn-xAg alloys, reacts with Zn to form AgZn3 intermetallic compounds (IMCs), which refined alloys changed mode surfaces from pitting corrosion. effectively improved passivation film structure electron transfer characteristics alloy, increased...
The effective dispersion and distribution control of reinforcements are crucial factors that influence the mechanical properties metal matrix composites. Here, we propose a strategy to disperse carbon nanotubes in aluminum composites using Ti "nano-grinding balls" as an auxiliary method, achieving interfacial/intragranular nano-reinforcements. Reinforcements with different dimensions can exert strengthening effects induce high density stacking faults (SFs) by generating high-stress regions...
In situ particle reinforced aluminum matrix composites have become an important development in the field of materials science due to their unique structure design and excellent mechanical properties. this paper, Al2O3 AlSi3Ti2 Al12Si were prepared via powder metallurgy. The microstructure properties analyzed systematically. With increase TiO2 content, grain size was refined, resulting exhibiting higher strength. generated phase has a Young’s modulus elasticity compared Si phase. formed...
The thermal‐electric coupling characteristics of combined heat and power (CHP) units make it critical problem to improve wind accommodation ability in the heating season. This study establishes a CHP dispatch model for better integration based on electric boiler with thermal storage (EBTS). A start–stop strategy EBTS is formulated that takes only abandoned as source. runs at maximum during curtailment, output changed by controlling endothermic exothermic rates storage. Considering scheduling...
In this study, Cu–9Ni–6Sn-xCr alloys (x = 0, 0.3, 0.6, or 1.0) were designed and prepared. The influence of Cr content on the microstructure, precipitation behavior, mechanical properties was systematically investigated. results show that Cu–9Ni–6Sn-0.6Cr alloy exhibits outstanding higher level electrical conductivity after aging at 400 °C for 8 h: peak-aged hardness reaches 323.6 ± 8.4 HV, with a tensile strength 876.4 MPa an 12.59 0.33% IACS. These excellent comprehensive are attribute to...
The mechanical properties of solder alloys are a performance that cannot be ignored in the field electronic packaging. In present study, novel Sn-Zn were designed by cluster-plus-glue-atom (CPGA) model. effect copper (Cu) addition on microstructure, tensile properties, wettability, interfacial characterization and melting behavior Sn-Zn-Cu investigated. Sn29Zn4.6Cu0.4 alloy exhibited fine but excessive substitution Cu atoms CPGA model resulted extremely coarse intermetallic compound (IMC)....
Pesticides are widely detected in large quantities the environment, posing an ecological threat to human body and ecology. Semiconductor nanomaterials such as nano-titania (nTiO2) have strong photocatalytic degradation efficiency for pollutants. However, wide bandgap limited light absorption range inhibit nano-titania’s practical application. Therefore, nTiO2 was modified by Fe3+ doping using microwave hydrothermal method improve its performance this study. Fe-nTiO2 doped with a 1.0% mass...
A novel high step-up DC–DC converter with a three-winding-coupled-inductor and an output capacitor in series is proposed this study. By charging for two windings of dotted terminal connection by input source, the can achieve higher gain using smaller turns ratios when active switch turned on. The passive clamping circuits are introduced not only recycling leakage energy but also alleviating voltage spike on main effectively. Meanwhile, reverse-recovery problem diode alleviated inductor....
