DIP无氧铜的氢脆试验分析

20134No．42013ElectricWire＆Cable20138Aug．2013DIP周林平，于友姬，李国昌，徐龙311400对不同批次的无氧铜杆进行了氢脆试验分析，比较了试验后的反复弯曲断裂次数、断面的形貌特征、金相组织的结构特点以及维氏硬度的变化。在实际生产中氢脆试验可以简单间接判断无氧铜杆中氧含量是否超标，对实际生产有一定的指导和帮助。DIP;无氧铜;氢脆;断面;金相组织;维氏硬度TM241A1672-6901201304-0029-03AnalysisoftheDIPOxygen-FreeCopperHydrogenEmbrittlementTestZHOULin-pingYUYou-jiLIGuo-changXULongFutongGroupCo．Ltd．Fuyang311400ChinaAbstractThedifferentbatchesofoxygen-freecopperrodforthehydrogenembrittlementtestanalysisthetestafterrepeatedbendingfracturesectionnumbersmorphologymetallographicstructureandhardnessofVivtorinoxarecom-pared．Thehydrogenembrittlementtestcanindirectlydeterminewhetherthecontentofoxygenfreecopperrodtoex-ceedthestandardintheactualproduction．Itwillbeguidancefulandhelpfulfortheactualproduction．KeywordsDIPOFChydrogenembrittlementsectionmicrostructurevickershardness2012-10-211982－．1－8311400．0OFC、。45%90%1。DIPSCR———。2。。、、、。“”2-3。。11.12#、8#、9#2mm。30cm2。1.2AMF-1PRO-116LEICADVM50005XB-PCHV-1000。1.361850℃30min。。1gRO-116。。122.12#、8#、9#1。1//2#8#9#2－115212－215238－117228－217239－11429－215219#2#、8#2#、8#。EMGA2#、8#、9#2#8#2.3ppm2.4ppm9#6.7ppm305ppm49#。2.22。2#、8#。9#。2.33。32。9#2#、8#9#。2.42。210s0.3kgf2#8#9#2－1105.02－2103.38－1113.58－2112.39－1107.69－2107.92·03·20134No．42013ElectricWire＆Cable20138Aug．2013。33110。2。。3。1．M．1983．2．M．1982295-314．3．M．1988127-129．4GB/T5231—2001S檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿檿．254FT2VW-1IEC60332-1。TMPU、。FT2。。5。－40～－15℃、、、、。。1．M．2001．2VDE0282-42005Cablesofratedvoltagesuptoandincluding450/750Vandhavingcrosslinkedinsulation-Part4CordsandflexiblecablesS．3HD22.102007Cablesofratedvoltagesuptoandincluding450/750Vandhavingcrosslinkedinsulation-Part10EPRin-sulatedandpolyurethanesheathedflexiblecablesS．4UL6218thEditionflexiblecordandcablesS．5．、J．200751-5．6PolyurethanesheathedmaterialZ．Techno-informationofBASF．7．105℃J．2012116-18．·13·20134No．42013ElectricWire＆Cable20138Aug．2013
