Ukuhlola kufakazele ithonya le-cerium ku-microstructure ye-ithusi le-tin-phosphorIngxubevange ye-QSn7-0.2 ephonswe, yenziwa i-homogenized futhi yaphinde yafakwa amakristalu.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, zicwengisa ukwakheka kwe-alloy, futhi ukungezwa kwe-cerium kuthuthukisa kakhulu amandla nobulukhuni be-alloy, futhi kunqunywa ukuthi inani elikhulu lokwengezwa kwe-cerium ehlathini lethusi le-tin ngu-0.1% -0.15% , okuthuthukisa ngempumelelo ukusebenza okuphelele kwe-alloy ye-bronze ye-tin yehlathi, futhi icule impilo yesevisi ye-alloy alloy material.
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.
