Impembelelo yeCerium kwiiPropati zeTin Phosphor Bronze Alloy

Iimvavanyo zibonakalise impembelelo ye-cerium kwi-microstructure ye-i-tin-phosphor ubheduI-alloy ye-QSn7-0.2 eye yaphoswa, i-homogenized kunye ne-recrystallized.Umnatha uba ngcono, kwaye ulwakhiwo lweenkozo luyacocwa ngokucacileyo emva kokwenziwa kwe-deformation annealing.Ukongeza inani elincinci le-cerium yomhlaba elinqabileyo liyakwazi ukuhlambulula ukungcola okuyingozi kwi-alloy okanye ukuphelisa umphumo walo onobungozi, kwaye unokuxutywa nobhedu ukwenza i-CuCeP intermetallic compounds, ezihlakazwa kwimida yengqolowa okanye iinkozo.Ezi zigaba zesibini, ezisasazwa kwiindawo ezincinci ezimnyama, zicokiseke kwisakhiwo se-alloy, kwaye ukongezwa kwe-cerium kuphucula kakhulu amandla kunye nobulukhuni be-alloy, kwaye kumiselwe ukuba isixa esikhulu sokongeza se-cerium ehlathini lobhedu lwe-0.1% -0.15% , ephucula ngokufanelekileyo ukusebenza okubanzi kwe-alloy ye-tin tin bronze, kwaye icula ubomi benkonzo yezinto zobhedu.
Ukuqina kwe-ingot ye-tin phosphor bronze kunye nobudlelwane phakathi kokuqina kokuqina kunye nobude bemizekelo yamaphepha kunye nomxholo we-cerium.Amandla kunye nobunzima be-tin phosphor bronze buya kunyuka ngokunyuka komxholo we-cerium wemveliso, kodwa xa umxholo we-cerium udlula i-0.125%, amandla kunye nobunzima bemveliso ayiyi kunyuka kakhulu;ukwanda kuyanda kunye nomxholo wecerium.Ukunyuka kwevolumu kunciphe kancinci.Ukuqwalasela ukuphucula iimpawu zomatshini we-alloy, umxholo ophezulu we-cerium we-tin phosphor bronze ngu-0.1% -0.15%.Ukuba umxholo we-cerium uphezulu kakhulu, iplastiki ye-alloy iya kuncipha kakhulu;ukuba umxholo we-cerium uphantsi kakhulu, umphumo wokuqiniswa kwezinto ezinqabileyo zomhlaba kwi-alloy aziyi kubaluleka.
