| 1 | Microstructure in the Weld Metal of Austenitic-Pearlitic Dissimilar Steels and Diffusion of Element in the Fusion Zone显示文摘Microstructure and alloy element distribution in the welded joint between austenitic stainless steel (1Cr18Ni9Ti) and pearlitic heat-resistant steel (lCr5Mo) were researched by means of light microscopy, scanning electron microscopy (SEM) and electron probe microanalysis (EPMA). Microstructure, divisions of the fusion zone and elemental diffusion distributions in the welded joints were investigated. Furthermore, solidification microstructure and &-ferrite distribution in the weld metal of these steels are also discussed. | Yajiang LI, Zengda ZOU and Bing ZHOU Department of Materials Engineering, Shandong University, Jinan 250061, China E-mail: yajli@jn-public.sd.cninfo.net | 2001 | Journal of Materials Science & Technology2001，17，3： | 6 |
| 2 | Effect of Thermal Cycle on Microstructure and Fracture Morphology in HAZ of HQ130 Steel显示文摘The effect of different peak temperature(T_P) and cooling time(t_(8/5)) on microstructure,hardness,impact toughness and fracture morphology in the heat-affected zone(HAZ) of HQ130 steel was studied by using weld thermo-simulation test.Experimental results indicate that the impact toughness and hardness decrease with the decrease of T_P or increase of t_(8/5) under the condition of a single thermal cycle.There is a brittle zone in the vicinity of T_P = 800 ℃,where the impact toughness is considerably low.There is a softened zone in the vicinity of T_P = 700℃,where the hardness decreases but the toughness increases.In the practical application of multi-layer and multipass welding,the welding heat input should be strictly limited(t_(8/5)≤20s) so as to reduce the softness and brittleness in the HAZ of HQ130 steel. | Li Yajiang Zou Zengda Cheng Zhunian Wei Xing Jiang Quanchang | 1996 | Journal of Iron and Steel Research(International)1996，3，2： | 3 |
| 3 | ATP11B deficiency leads to impairment of hippocampal synaptic plasticity显示文摘Synaptic plasticity is known to regulate and support signal transduction between neurons, while synaptic dysfunction contributes to multiple neurological and other brain disorders;however, the specific mechanism underlying this process remains unclear. In the present study, abnormal neural and dendritic morphology was observed in the hippocampus following knockout of Atpllb both in vitro and in vivo. Moreover, ATP11B modified synaptic ultrastructure and promoted spine remodeling via the asymmetrical distribution of phosphatidylserine and enhancement of glutamate release, glutamate receptor expression, and intracellular Ca^2+ concentration. Fuithermoe experimental results also indicate that ATP11B regulated synaptic plasticity in hippocampal neurons through the MAPK14 signaling pathway. In conclusion, our data shed light on the possible mechanisms underlying the regulation of synaptic plasticity and lay the foundation for the exploration of proteins involved in signal transduction during this process. | Jiao Wang Weihao Li Fangfang Zhou Ruili Feng Fushuai Wang Shibo Zhang Jie Li Qian Li Yajiang Wang Jiang Xie Tieqiao Wen | 2019 | Journal of Molecular Cell Biology2019，11，8： | 2 |
