Kuedza kwakaratidza simba recerium pane microstructure yetin-phosphor bronzeQSn7-0.2 alloy yakakandwa, yakaitwa homogenized uye yakadzokororwa.Iyo mesh inova yakanaka, uye chimiro chezviyo chiri pachena chakanatswa mushure me deformation annealing.Kuwedzera shoma shoma yepasi isingawanzo cerium inogona kuchenesa tsvina inokuvadza mualloy kana kubvisa mhedzisiro yayo inokuvadza, uye inogona kusanganiswa nemhangura kuti iite CuCeP intermetallic compounds, iyo inoparadzirwa mumiganhu yezviyo kana zviyo.Izvi zvikamu zvechipiri, izvo zvakagoverwa munzvimbo diki nhema, inonatsiridza iyo alloy chimiro, uye kuwedzera kwecerium kunovandudza zvakanyanya kusimba uye kuoma kweiyo alloy, uye zvakatemwa kuti iyo optimum yekuwedzera huwandu hwecerium musango tin bronze i0.1% -0.15% , iyo inobudirira inovandudza kushanda kwakazara kwemasango tin bronze alloy, uye inoimba hupenyu hwebasa remhangura yemhangura.
Ingot kuomarara kwetin phosphor bronze uye hukama pakati pesimba rekusimba uye kurebesa kwemashizha emuenzaniso uye cerium zvirimo.Simba uye kuoma kwetin phosphor bronze kuchawedzera nekuwedzera kwecerium yezvigadzirwa zvechigadzirwa, asi kana zvinyorwa zvecerium zvinopfuura 0.125%, simba uye kuoma kwechigadzirwa hazvizowedzera zvakanyanya;iyo elongation inowedzera nehuwandu hwecerium.Kuwedzera kwezwi kwakadzikira zvishoma.Tichifunga nezvekuvandudza ma mechanical properties yealloy, iyo optimum cerium content ye tin phosphor bronze ndeye 0.1% -0.15%.Kana zvinyorwa zvecerium zvakanyanyisa, plastiki yealloy ichaderera zvakanyanya;kana iyo cerium yemukati yakaderera zvakanyanya, iyo yekusimbisa mhedzisiro yezvinhu zvisingawanzo pasi pane alloy hazvizove zvakakosha.
