Influence of Sc content on microstructure and stress corrosion cracking behavior of medium strength AI-Zn-Mg alloy have been investigated by optical microscopy, scanning electron microscopy, electron backscatter diffraction, transmission electron microscopy and slow strain rate test. The results indicate that the addition of Sc results in the formation of the quaternary coherent AI3（Sc, Zr, Ti） dispersoids during homogenization treatment, which will inhibit the dynamic recrystallization behavior. The number density ofAl3（Sc, Zr, Ti） particles increases with the increase of Sc content, and thus the recrystallization fraction of hot-extruded alloy is reduced and the peak strength in two-stage artificial aging sample is enhanced. At the same time, the wide of precipitation free zone is reduced, and the content of Zn and Mg in grain boundary particles and precipitation free zone is increased with the increase of Sc content. In peak-aged state, the 0.06 wt% Sc added alloy shows the better stress corrosion cracking resistance than the Sc-free alloy because of the reduction of recrystallization fraction and the interrupted distribution of grain boundary precipitates along grain boundary. However, the further addition of Sc to 0.11 wt% will result in the deterioration of stress corrosion cracking resistance due to the increase of electrochemical activity of grain boundary particles and precipitation free zone as well as hydrogen embrittlement.2017 Published by Elsevier Ltd on behalf of The editorial office of Journal of Materials Science ＆ Technology.

A new cast Mg-2Gd-2Nd-2Y-1Ho-1Er-0.5Zn-0.4Zr （wt%） alloy was prepared by direct-chill semicontinuous casting technology. The microstructure, mechanical properties and thermal conductivity of the alloy in as-cast, solid-solution treated and especially peak-aged conditions were investigated. The as-cast alloy mainly consists of α-Mg matrix, （Mg, Zn）3 RE phase and basal plane stacking faults. After proper solid-solution treatment, the microstructure becomes almost Mg-based single phase solid solution except just very few RE-riched particles. The as-cast and solid-solution treated alloys exhibit moderate tensile properties and thermal conductivity. It is noteworthy that the Mg alloy with 8 wt% multiple RE exhibits remarkable age-hardening response （AHV=35.7）, which demonstrates that the multiple RE （RE = Gd, Nd, Y, Ho, Er） alloying instead of single Gd can effectively improve the age-hardening response. The peak-aged alloy has a relatively good combination of high strength/hardness （UTS （ultimate tensile strength）〉 300 MPa; TYS （tensile yield strength）〉210 MPa; 115.3 HV）, proper ductility （ε≈ 6%） and moderate thermal conductivity （52.5 W/（m K））. The relative mechanisms mainly involving aging precipitation of β″ and β＂ phases were discussed. The results provide a basis for development of high performance cast Mg alloys.2017 Published by Elsevier Ltd on behalf of The editorial office of Journal of Materials Science ＆ Technology.

【目的】通过分析我国卓越农业期刊和农业领域高起点新刊的发展现状,探索我国农业期刊发展趋势,提出对我国农业期刊发展的启示,为我国农业期刊的高质量发展提供参考。【方法】以2019年入选“中国科技期刊卓越行动计划”(以下简称“卓越计划”)的19种农业期刊、2019—2023年入选“卓越计划”高起点新刊项目的农业期刊为研究对象,从卓越农业期刊优先建设的农业领域学科分布、期刊国内影响力、期刊国际影响力和农业领域高起点新刊的基本特征4个方面分析我国卓越农业期刊的发展趋势,并总结出对我国农业期刊整体高质量发展的启示及展望。【结果】与中国科协、中国科学院和农业农村部主管的农业期刊相比,教育部主管的农业高校所办期刊实力相对较弱,存在“强学科与弱期刊”现象,入选“卓越计划”的农业期刊数量较少。我国农业高校近年已在优势学科中全面布局,高起点新刊的数量呈上升趋势,同时通过挖掘交叉学科的空白领域,创办一批强劲新刊以逐步实现农业期刊与学科协同发展。【结论】我国农业领域虽然入选“卓越计划”的期刊数量较少,但优势学科明显,期刊发展动力十足,势头强劲,呈显著上升趋势。我国卓越农业期刊优先发展,将带动普通农业期刊共同发展。
