Tin bronze (Cu–Sn–Zn system) was employed as the base alloy. Specimens were prepared by sand casting methods. Ingots of JIS CAC403 were melted using a high–frequency induction furnace, followed by the addition of an alloy containing sulfur. Specimens were subjected to strength tests and machinability tests. The sulfur was crystallized as sulfide particle composed of Cu<sub>2</sub>S and ZnS among the branches of dendrite of copper solid solution. There was not high correlation between sulfur content of specimens and tensile strength or breaking elongation. It was considered that more influence on mechanical properties other factors, such as gas dissolution, than sulfur content. When the sulfur concentration was larger than 0.23mass%, machining resistance decreased about 15%. Sulfide particles behaved as a chip breaker. Further Cu<sub>2</sub>S adhered cutting edge of machining chip, and behaved as solid lubricant.</p>"}],"abstractLicenseFlag":"allow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410302093672484225","@type":"Researcher","foaf:name":[{"@language":"ja","@value":"安田 吉伸"},{"@language":"en","@value":"Yasuda Yoshinobu"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Northeastern Industrial Research Center of Shiga Prefecture"},{"@language":"ja","@value":"滋賀県東北部工業技術センター"}]},{"@id":"https://cir.nii.ac.jp/crid/1410302093672484353","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Mase Satoshi"},{"@language":"ja","@value":"間瀬 慧"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Northeastern Industrial Research Center of Shiga Prefecture"},{"@language":"ja","@value":"滋賀県東北部工業技術センター"},{"@language":"ja","@value":"現：滋賀県工業技術総合センター"},{"@language":"en","@value":"Present：Integrated Industrial Research Center of Shiga Prefecture"}]},{"@id":"https://cir.nii.ac.jp/crid/1410302093672484352","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Imada Takumi"},{"@language":"ja","@value":"今田 琢巳"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"滋賀県工業技術総合センター"},{"@language":"en","@value":"Integrated Industrial Research Center of Shiga Prefecture"},{"@language":"en","@value":"Present：Ryukoku University, Faculty of Advanced Science and Technology"},{"@language":"ja","@value":"現：龍谷大学　先端理工学部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410302093672484224","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Matsubayashi Masaki"},{"@language":"ja","@value":"松林 正樹"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Matsubayashi Co., Ltd."},{"@language":"ja","@value":"株式会社マツバヤシ"}]},{"@id":"https://cir.nii.ac.jp/crid/1410302093672484354","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Maruyama Toru"},{"@language":"ja","@value":"丸山 徹"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"関西大学　化学生命工学部 化学・物質工学科"},{"@language":"en","@value":"Department of Chemistry and Materials Engineering, Faculty of Chemistry, Materials and Bioengineering, Kansai University"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"13477234"},{"@type":"EISSN","@value":"2435872X"},{"@type":"NDL_BIB_ID","@value":"000003536269"},{"@type":"ISSN","@value":"13477234"},{"@type":"LISSN","@value":"13477234"},{"@type":"NCID","@value":"AA11995570"}],"prism:publicationName":[{"@language":"en","@value":"Journal of Japan Institute of Copper"},{"@language":"ja","@value":"銅と銅合金"}],"dc:publisher":[{"@language":"en","@value":"Japan Institute of Copper"},{"@language":"ja","@value":"日本銅学会"}],"prism:publicationDate":"2024","prism:volume":"63","prism:number":"1","prism:startingPage":"247","prism:endingPage":"252"},"url":[{"@id":"http://id.ndl.go.jp/bib/033688952"},{"@id":"https://ndlsearch.ndl.go.jp/books/R000000004-I033688952"}],"availableAt":"2024","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=bronze","dc:title":"bronze"},{"@id":"https://cir.nii.ac.jp/all?q=sulfur","dc:title":"sulfur"},{"@id":"https://cir.nii.ac.jp/all?q=microstructure","dc:title":"microstructure"},{"@id":"https://cir.nii.ac.jp/all?q=strength","dc:title":"strength"},{"@id":"https://cir.nii.ac.jp/all?q=machinability","dc:title":"machinability"},{"@id":"https://cir.nii.ac.jp/all?q=cutting%20resistance","dc:title":"cutting resistance"},{"@id":"https://cir.nii.ac.jp/all?q=bronze","dc:title":"bronze"},{"@id":"https://cir.nii.ac.jp/all?q=sulfur","dc:title":"sulfur"},{"@id":"https://cir.nii.ac.jp/all?q=microstructure","dc:title":"microstructure"},{"@id":"https://cir.nii.ac.jp/all?q=strength","dc:title":"strength"},{"@id":"https://cir.nii.ac.jp/all?q=machinability","dc:title":"machinability"},{"@id":"https://cir.nii.ac.jp/all?q=cutting%20resistance","dc:title":"cutting resistance"}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:2013441605"},{"@type":"NDL_SEARCH","@value":"oai:ndlsearch.ndl.go.jp:R000000004-I033688952"}]}
