基于文献计量和知识图谱的冶金学科研究前沿分析

Frontal Analysis of Metallurgy Based on Bibliometrics and Knowledge Mapping

通过收集中文核心期刊(CNKI数据库)和科学引文索引(SCI-E)中2010—2016年间冶金学科领域研究文献,并运用知识图谱技术和文献计量方法对数据进行定性和定量分析,推演2010—2016年冶金学科的研究轨迹和研究热点。结果表明:从时间序列上看,冶金学科研究处于一个高位、稳定的成熟阶段;从冶金学科文献中关键节点文献相关信息来看,6篇关键节点文献分别来自美国、日本和德国,关键节点文献主要研究方向主要是机械合金化(MA)、金属泡沫材料或其他多孔金属结构、纯铁碳合金等;2015—2016年的研究热点是mu-m、基复合材料、断裂面、热点热循环、热处理、滑动轴承、耐磨涂层、耐腐蚀性、热变形、冲击韧性、镍基高温合金能等;各国在研究冶金学科研究领域存在明显的层次差异。

The study collected the metallurgical literature from Chinese core periodicals in China National Knowledge Infrastructure (CNKI) and Science Citation Index (SCI-E) during 2010-2016.A quantitative statistical and a qualitative analysis of metallurgy discipline research literature were made with bibliometrics and knowledge mapping.And metallurgical science research trajectory and the research hotspot from 2010-2016 were deduced.The results showed that from the time series,the study of metallurgical discipline is in a high and stable mature stage.From the relevant information of key points in the metallurgical discipline literature,6 key nodes paper respectively come from the United States,Japan and Germany,whose main research direction were mainly mechanical alloying (MA),metallic foams,or other structure of porous metal,pure iron carbon alloy,etc.;The hot research areas in 2015-2016 were mu-m,matrix composites,fracture,hot thermal cycle,heat treatment,sliding bearing,wear resistant coating,corrosion resistance,thermal deformation,impact toughness,Nickel base high temperature alloy energy,etc..There were obvious level differences in the research fields of metallurgical discipline.
