| 1 | Deformation Temperature Dependence of Mechanical Properties and Microstructures for a Novel Quenching—Partitioning—Tempering Steel显示文摘The present investigation on a designed high strength Fe-0.25C-1.48Mn-1.20Si-1.51Ni-0.05Nb(wt%) steel treated by a novel quenching—partitioning—tempering(Q—P—T) process was focused on deformation temperature dependence of mechanical properties and microstructures.The results indicate that the Q—P—T steel deformed at various deformation temperatures from -70 to 300℃exhibits superior mechanical properties due to excellent thermal stability of retained austenite.The microstructural characterization by transmission electron microscopy(TEM) reveals that the high strength of the Q—P-T steel results from dislocation-type martensite laths and fcc NbC carbides or/and hcpε-carbides precipitated dispersively in martensite matrix,while excellent ductility is attributed to the significant transformation induced plasticity (TRIP) effect produced by considerable amount of retained austenite.The relationship between mechanical properties and microstructures at different deformation temperatures was clarified. | Ying Wang Zhenghong Guo Nailu Chen Yonghua Rong | 2013 | Journal of Materials Science & Technology2013，29，5： | 5 |
| 2 | Dynamic Compression Behavior and Microstructure of a Novel Low-Carbon Quenching-Partitioning-Tempering Steel显示文摘A 0.2C-1.5Mn-1.5Si-0.6Cr-0.05Nb(wt%) steel is treated respectively by novel quenching-partitioning-tempering(Q-P-T) process and traditional quenching and tempering(Q&T) process for comparison. X-ray diffraction analysis indicates that Q-P-T steel has about 10% retained austenite, but Q&T steel hardly has one. With the increase of compression strain rate from 7 9 102 to 5 9 103s-1, the flow stress of Q-P-T steel increases, which demonstrates the positive strain rate effect, but does not exist in Q&T steel. The characterization of scanning electron microscopy indicates that a large number of long, straight martensite laths in Q-P-T steel will bend or be destroyed by large compressive strain of 35%at 5 9 103s-1. However, relative small compressive strain of about 5% at 7 9 102s-1almost does not have any effect on the original lath morphology. The characterization of transmission electron microscopy further reveals the origin of the positive strain rate effect and the microstructural evolution during dynamic compressive deformation. | Qingguo Hao Ying Wang Xiaoshuai Jia Xunwei Zuo Nailu Chen Yonghua Rong | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，3： | 5 |

| 4 | Application of the Controllable Quenching Technology to the Quenching and tempering Workpieces显示文摘In order to obtain the desired mechanical properties of quenching and tempering workpieces, as well as reduce the cracking tendency and distortion, a program of controllable quenching was established. Furthermore, a computer-aided quenching system (CAQ) was also developed. The application samples of the CAQ system showed satisfactory results. | Chen Nailu, Liao Bo, Niu Wanbin’, Slum Jin, Zhu Xiaoqian 1.Zhengzhou Research Institute of Mechanical Engineering, Zhengzhou 450052,China 2.Department of Materials, University of Yanshan, Qinhuangdao 066004, China | 2000 | Journal of Shanghai Jiaotong university(Science)2000，5，1： | 2 |

| 9 | Computer simulation of flow fields for quenching medium显示文摘Using finite element method (FEM), the com-plex flow fields of quenching medium in a quenching tank are calculated for the cases with and without a work-piece in it. The influence of the flow homogenization device on the flow fields is studied. The computer simulation results are in consistency with the actual measurement results. According to the simulated results, the structure of the quenching tank and the flow homogenization device are optimized and more uniform flow fields are obtained. | LI Qiang, WANG Ge, CHEN Nailu, LIAO Bo & WANG Tongzhen College of Mechanical Engineering, Yanshan University, Qinhuangdao 066004, China Correspondence should be addressed to Li Qiang (e-mail: Liqiang@ ysu.edu.cn) | 2003 | Chinese Science Bulletin2003，48，8： | 1 |

| 11 | Achieving stable K-storage performance of carbon sphere-confined Sb via electrolyte regulation显示文摘Potassium-ion batteries(PIBs)have been considered as one of the most promising alternatives to lithiumion batteries(LIBs)in view of their competitive energy density with significantly reduced product cost.Moreover,alloy-type materials are expected as a high-performance anode of PIBs thanks to their intrinsic chemical stability as well as high theoretical specific capacity.Unfortunately,the serious incompatibility between alloy-type active materials and electrolytes,especially for the formation of unstable solidelectrolyte interfacial(SEI)films,often leads to insufficient cycle life.Herein,the formation mechanism of SEI films in the K-storage systems based on carbon sphere confined Sb anode(Sb@CS)were investigated in commercially available electrolytes.Physical characterizations and theoretical calculation revealed that the solvents in the dilute electrolyte of 0.8 M KPF_(6)/EC+DEC were excessively decomposed on the interface to generate unstable SEI and thus result in inferior K-storage stability.On the contrary,a salt-concentrated electrolyte(3 M KFSI/DME)can generate inorganic-dominated stable SEI due to the preferential decomposition of anions.As a result,the prepared Sb@CS in the matched 3 M KFSI/DME electrolyte delivered a high reversible capacity of 467.8 m A h g^(-1)after 100 cycles at 100 m A g^(-1),with a slow capacity decay of 0.19%per cycle from the 10th to the 100th cycle.These findings are of great significance for revealing the interfacial reaction between electrodes and electrolytes as well as improving the stability of Sb-based anode materials for PIBs. | Ningning Chen Nailu Shen Xiaoping Yi Yinshuang Pang Jing Zheng Qingxue Lai Yanyu Liang | 2023 | Journal of Energy Chemistry2023，，1： | 1 |
