Journal of Wuhan University of Technology(Materials Science) 2025年第1期40卷 49-64页

作者： WANG Xin SHEN Dejian TAO Sijie liu Ruixin WU Shengxing college of civil and Transportation Engineering Hohai UniversityNanjing 210098China

This study aims to develop a chloride diffusion simulation method that considers the hydration microstructure and pore solution properties during the hydration of tricalcium silicate(c3S).The method combines the hydration simulation,thermodynamic calculation,and finite element analysis to examine the effects of pore solution,including effect of electrochemical potential,effect of chemical activity,and effect of mechanical interactions between ions,on the chloride effective diffusion coefficient of hydrated c3S *** results indicate that the effect of electrochemical potential on chloride diffusion becomes stronger with increasing hydration age due to the increase in the content of hydrated calcium silicate;as the hydration age increases,the effect of chemical activity on chloride diffusion weakens when the number of diffusible elements decreases;the effect of mechanical interactions between ions on chloride diffusion decreases with the increase of hydration age.

Developing a bridge capping layer between perovskite and hole transport layer materials（HTMs） in the n-i-p perovskite solar cells（pero-Scs） is an effective approach to modify the morphology of HTMs and passivate the perovskite ***, we select the quinoxaline-based bifunctional passivation agent, quinoxalin-6-yl-methylamine hydrochloride（Qx MAcl）,as the bridging layer, and a D-A copolymer PBQ12 containing the same quinoxaline unit as an HTM for the n-i-p pero-Scs. Due to the π-π stacking among the common quinoxaline units in the bridge layer and HTM, Qx MAcl induces the π-π stacking of the PBQ12 film and improves the film morphology of HTMs with better conductivity. Additionally, Qx MAcl can effectively passivate the perovskite surface, and PBQ12 possesses appropriate energy levels and high hole mobility. The pero-Scs based on FAPbI3with PBQ12/Qx MAcl treatment showed a higher power conversion efficiency（PcE） of 24.05% and outstanding stability, maintaining 95.4% and 92.1% of its initial PcE after 750 h of storage and after over 800 h of thermal annealing at 85 °c, respectively. To further enhance the PcE of the PBQ12/Qx MAcl-based devices, we developed a non-metal ion dopant for the PBQ12 HTM. Through trace doping of PBQ12 HTM by the non-metal ion dopant, the PcE of the PBQ12/Qx MAcl-based devices reached 25.24%（the calibrated PcE of 24.55% by the National Institute of Metrology, china）.

Effects of Boron Addition on Grain Refinement in TiAl-based Alloys

Solid state phase transformation characteristics of the body.c.ntred β（Ti） into the hexagonal closed packed α（Ti） in Ti45AI8Nb-（0, 0.3, 0.5 and 0.8 at. pct） B alloys were investigated by heat treatment to clarify γ/α2 lamellar microstructure refinement induced by B addition. Experimental results confirmed two kinds of boron-reduced grain refinement mechanisms through refining either/β phase then α phase （β-refinement） or α phase directly （α-refinement） to refine lamellar microstructure at room temperature; however, the role of α-refinement dominated the as-cast alloy. It was also found that during the lamellar microstructure refinement β-refinement the convoluted flake over β-refinement in Ti45Al8NbxB and plate-like borides along β grain boundaries assisted nucleation of α phase, and the particle-like borides nearβ grain boundaries impeded α phase growth.
