文档简介

1、检索课题名称:稀土元素铈对奥氏体不锈钢力学性能、耐蚀性及抗菌性影响的研究2、课题分析:我国稀土产量及储量均世界前列,但对稀土的利用及研究却低于国外先进水平。本实验目的是研究稀土元素铈在奥氏体不锈钢中对组织、耐蚀性及抗菌性的作用,并在稀土抗菌材料科学领域进行初步探索:中文关键词:1奥氏体不锈钢2稀土元素铈3耐蚀性4力学强度5抗菌性英文关键词:(1)austeniticstainlesssteel(2)rareearthelementcerium(3)corrosionresistance(4)mechanicalstrength(5)antibacterialproperty3、选择检索工具:本课题检索目标为中文各类相关文献。根据本图书馆的资源情况选择如下数据库:(1)CNKI数据库(外网):中国期刊全文数据库(2)万方数据库(会议论文)(3)超星数字图书馆(图书检索)。4、构建检索策略:“稀土元素铈对奥氏体不锈钢的组织性能的影响”是研究的主体,应优先检索,“稀土元素的物理化学性质”和“奥氏体不锈钢的组织与性能”应在检索结果中同时存在。故制定如下检索策略。“()”表示优先、“*”表示并且。检索算法:(稀土元素铈对奥氏体不锈钢的组织性能的影响)*稀土元素的物理化学性能*奥氏体不锈钢的组织与性能时间范围:2009-2012文献范围:期刊论文、专著为了保证查全率可考虑使用全文检索途径和高级检索方式。5、简述检索策略调整的过程:1)在CNKI中国期刊全文数据库中(CNKI数据库镜像):a、为保证查全率,使用“(稀土元素铈对奥氏体不锈钢的组织性能的影响)*稀土元素的物理化学性能*奥氏体不锈钢的组织与性能”检索运算式,检索项:篇名,检索范围选择:全部期刊中检索,检索出记录0条。b、上述检索策略得到的检索结果0条太少,考虑扩大检索范围。改篇名检索项为全文检索。使用“(稀土元素铈对奥氏体不锈钢的组织性能的影响)*稀土元素的物理化学性能*奥氏体不锈钢的组织与性能”检索运算式,检索范围选择:全部期刊,检索出记录21条,数量适中。c、检索结果的满意度,可根据检索者的需要不断调整。检索字段的选择,可单一,也可以混编,直至满意。2)万方数据库(会议论文):a、由于“万方数据库(会议论文)”收录的文献比较单一,为保证查全率,使用“(稀土元素铈对奥氏体不锈钢的组织性能的影响)*稀土元素的物理化学性能*奥氏体不锈钢的组织与性能”检索运算式,检索范围选择:全字段中检索,不限定年代,检索出记录0条。b、上述检索策略得到的检索结果0条。考虑检索算式复杂,可简单一些。由于本课题的主体是“稀土元素铈对奥氏体不锈钢的组织性能的影响”,改用“稀土元素对不锈钢的组织性能的影响”单一算式检索,检索出记录1条。c、对于数据库收录的文献少、品种单一的情况,目标文献的相关度可适当放宽,以便获得更多的参考文献。3)超星数字图书馆:A、图书类文献属于成熟类知识,出版的数量少且与课题的相关度低,检索时应尽量扩大检索范围。图书类数据库的著录比较简单,可供检索的字段少且不规范,检索时尽量选用默认字段。使用高级检索中的书名检索,不限定年代。检索式(稀土元素铈对奥氏体不锈钢的组织性能的影响+稀土元素的物理化学性能+奥氏体不锈钢的组织与性能),检索出记录0条。B、调整检索策略,改为全文检索。用“稀土元素的物理化学性质”单一算式在全文中检索,检索出记录4条。6、整理检索结果:(1)CNKI中国期刊全文数据库有关专辑检索结果(选1条):铈对1Cr17不锈钢夹杂物的影响【英文篇名】EffectofCeriumontheShapesoftheInclusionsin1Cr17StainlessSteel【作者】徐掌印;张峰;姜银举;【英文作者】XUZhang-yin;ZHANGfeng;Jiangyin-ju(MaterialandMetallurySchool;InnerMongoliaScienceandTechnologyUniversity;Baotou014010;China);【作者单位】内蒙古科技大学材料与冶金学院;【刊名】稀土,ChineseRareEarths,编辑部邮箱2010年02期期刊荣誉:中文核心期刊要目总览ASPT来源刊CJFD收录刊【关键词】铈;1Cr17不锈钢;净化;夹杂物;【英文关键词】cerium;1Cr17stainlesssteel;purification;inclusions;【摘要】 采用金相显微镜、扫描电镜等分析测试手段研究了Ce对1Cr17不锈钢的净化作用及其夹杂物的形态和颗粒直径的影响。结果表明,Ce可使1Cr17钢中的夹杂物的含量显著降低,夹杂物的形态变小,高温机械性能提高。(2)万方数据库检索结果(1条):稀土对430铁素体不锈钢凝固组织和性能的影响作者:王龙妹,徐彪,朱京希(钢铁研究总院工艺所,北京100081)徐军,戚国平(宝钢股份不锈钢分公司技术中心,上海200431)团体责任者:会议名称:中国工程院化工·冶金与材料工程学部第六届学术会议会议时间:2007年10月23日会议地点:济南主办单位:中国工程院母体文献:中国工程院化工·冶金与材料工程学部第六届学术会议论文集出版单位:出版时间:页码:分类号:关键词:稀土铁素体不锈钢凝固组织塑性应变摘要:本文报道了稀土对430铁素体不锈钢凝固组织性能的影响,稀土细化柱状晶,扩大中心等轴晶区域,并且初步分析了稀土元素改善凝固组织的作者机理;稀土提高430铁素体不锈钢冷轧板的塑性应变比率的平均值,可改善薄板成型性能。(3)超星数字图书馆(1条):《铸铁及熔化(下册)(试用教材)》作者:北京钢铁学院铸工教研组页数:出版日期:主题词:稀土元素的物理化学性质简介:7、标示原文线索:(1)铈对1Cr17不锈钢夹杂物的影响【作者】徐掌印;张峰;姜银举;【作者单位】内蒙古科技大学材料与冶金学院;【刊名】稀土,ChineseRareEarths,编辑部邮箱2010年02期期刊荣誉:中文核心期刊要目总览ASPT来源刊CJFD收录刊(2)稀土对430铁素体不锈钢凝固组织和性能的影响作者:王龙妹,徐彪,朱京希(钢铁研究总院工艺所,北京100081)徐军,戚国平(宝钢股份不锈钢分公司技术中心,上海200431)团体责任者:会议名称:中国工程院化工•冶金与材料工程学部第六届学术会议会议时间:2007年10月23日会议地点:济南主办单位:中国工程院母体文献:中国工程院化工•冶金与材料工程学部第六届学术会议论文集出版时间:(3)《铸铁及熔化(下册)(试用教材)》作者:北京钢铁学院铸工教研组出版日期:(二)利用网络检索工具与搜索引擎1、检索课题名称:稀土元素铈对奥氏体不锈钢力学性能、耐蚀性及抗菌性影响的研究2、课题分析:我国稀土产量及储量均世界前列,但对稀土的利用及研究却低于国外先进水平。本实验目的是研究稀土元素铈在奥氏体不锈钢中对组织、耐蚀性及抗菌性的作用,并在稀土抗菌材料科学领域进行初步探索:中文关键词:1奥氏体不锈钢2稀土元素铈3耐蚀性4力学强度5抗菌性英文关键词:(1)austeniticstainlesssteel(2)rareearthelementcerium(3)corrosionresistance(4)mechanicalstrength(5)antibacterialproperty3、选择搜索引擎:1谷歌(google)2百度(baidu)3360综合搜索()4、构建检索策略:检索算法:(稀土元素铈对奥氏体不锈钢的组织性能的影响)*稀土元素的物理化学性质*奥氏体不锈钢的组织与性能文献范围:期刊论文、学位论文、会议论文、专著使用学术类文献检索、选择。5、简述检索策略调整的过程:1)在谷歌(google):使用“(稀土元素对奥氏体不锈钢的影响)*稀土元素的物理化学性质*奥氏体不锈钢的组织与性能”检索运算式,约有613,000项符合(稀土元素对奥氏体不锈钢的影响)*稀土元素的物理化学性质*奥氏体不锈钢的组织与性能的查询结果。2)百度(baidu):使用“(稀土元素对奥氏体不锈钢的影响)*稀土元素的物理化学性能*奥氏体不锈钢的组织与性能”检索运算式,百度一下,找到相关网页约2,220,000篇。3)360综合搜索():使用检索式“(稀土元素对奥氏体不锈钢的影响)*稀土元素的物理化学性质*奥氏体不锈钢的组织与性能”,综合搜索结果,找到相关网页约14,000篇。6、整理检索结果:(1)谷歌(google)(选1条)。稀土元素Ce对超级双相不锈钢组织与热加工性能的影响RareearthelementCetosuperduplexstainlesssteelorganizationandtheeffectonthepropertiesofhotworking...超级双相不锈钢的热加工的性能以及良好的综合力学性能等特点而被广泛地应用于化学、石化、...对铸态00Cr25Ni7Mo4N超级双相不锈钢的显微组织的研究表明:稀土Ce是一种奥氏体形成元素,可以细一点也是其使用不当,污染钢液的表1-1钢中稀土化合物的物理性质[9]...作者:傅绪鑫–2009-2-25相关文章(2)百度(baidu)(选1条)。一种含有稀土元素的奥氏体不锈钢Akindofrareearthelementcontainstheausteniticstainlesssteel本发明提供了一种含稀土元素的奥氏体不锈钢,该钢的化学成分重量百分比为:C≤0.06%,Cr:17.0-19.0%,Mn:0.5-0.7%,Ni:8.5-10.5%,稀土元素...
