Ukuhlola kufakazele ithonya le-cerium ku-microstructure ye-ithusi le-tin-phosphorIngxubevange ye-QSn7-0.2 ephonswe, yenziwa i-homogenized futhi yaphinde yacwebezelwa.I-mesh iba yinhle, futhi ukwakheka okusanhlamvu ngokusobala kucwengisiswa ngemuva kokukhishwa kwe-deformation.Ukwengeza inani elincane le-cerium yomhlaba engavamile kungahlanza ukungcola okuyingozi ku-alloy noma kuqede umphumela wawo oyingozi, futhi kungaxutshwa nethusi ukuze kwakhiwe ama-CuCeP intermetallic compounds, ahlakazeka emingceleni yokusanhlamvu noma okusanhlamvu.Lezi zigaba zesibili, ezisatshalaliswa ezindaweni ezincane ezimnyama, zicwengisisa isakhiwo se-alloy, futhi ukungezwa kwe-cerium kuthuthukisa kakhulu amandla nobulukhuni be-alloy, futhi kunqunywa ukuthi inani elikhulu lokwengezwa kwe-cerium ehlathini lethusi lethusi liyi-0.1% -0.15% , okuthuthukisa ngempumelelo ukusebenza okubanzi kwe-corolloy ye-corolloy, i-bronze ye-bronze kanye ne-bronze ye-bronze ye-bronze yehlathi, i-bronze ye-bronze kanye ne-bronze.
Ubulukhuni be-ingot be-tin phosphor bronze kanye nobudlelwano phakathi kwamandla aqinile nobude besampula yeshidi nokuqukethwe kwe-cerium.Amandla nokuqina kwethusi le-tin phosphor kuzokwanda ngokwanda kokuqukethwe kwe-cerium yomkhiqizo, kodwa lapho okuqukethwe kwe-cerium kudlula i-0.125%, amandla nobulukhuni bomkhiqizo ngeke kwande kakhulu;ukuphakama kuyanda ngokuqukethwe kwe-cerium.Ukwenyuka kwevolumu kwehle kancane.Uma kucatshangelwa ukuthuthukisa izakhiwo zemishini ye-alloy, okuqukethwe kwe-cerium kwe-tin phosphor bronze kungu-0.1% -0.15%.Uma okuqukethwe kwe-cerium kuphezulu kakhulu, i-plasticity ye-alloy izokwehla kakhulu;uma okuqukethwe kwe-cerium kuphansi kakhulu, umphumela wokuqinisa wezinto ezingavamile zomhlaba ku-alloy ngeke ube ophawulekayo.
