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 iyo inokuvadza, uye inogona kusanganiswa nemhangura kuumba CuCeP intermetallic compounds, iyo yakaparadzirwa mumiganhu yezviyo kana zviyo.Zvikamu zvechipiri izvi, izvo zvakagoverwa munzvimbo diki dema, inonatsa chimiro chealloy, uye kuwedzera kwecerium kunowedzera kusimba uye kuoma kweiyo alloy, uye zvinotemerwa kuti iyo yakakwana yekuwedzera huwandu hwecerium musango tin bronze ndeye 0.1% -0.15% , iyo inonyatso kuvandudza mashandiro akazara ebasa resango, bronze uye simbi.
Ingot kuomarara kwetin phosphor bronze uye hukama pakati pesimba rekusimba uye kurebesa kwemashizha emuenzaniso uye cerium zvirimo.Simba uye kuoma kwetini 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 yakanyanya kuderera, iyo yekusimbisa mhedzisiro yezvinhu zvisingawanzo pasi pane alloy hazvizove zvakakosha.
