Mphamvu ya Cerium pa Katundu wa Tin Phosphor Bronze Alloy

Kuyesera kwatsimikizira mphamvu ya cerium pa microstructure yatin-phosphor mkuwaQSn7-0.2 alloy yomwe yaponyedwa, yopangidwa ndi homogenized ndi recrystallized.Ukondewo umakhala wowoneka bwino, ndipo kapangidwe kake kake kamakonzedwanso bwino pambuyo pa deformation annealing.Kuwonjezera pang'ono cerium lapansi osowa kwambiri akhoza kuyeretsa zonyansa zoipa mu aloyi kapena kuthetsa zotsatira zake zoipa, ndipo akhoza kusakaniza mkuwa kupanga CuCeP intermetallic mankhwala, amene anamwazikana mu malire a tirigu kapena mbewu.magawo achiwiri awa, amene anagawira ang'onoang'ono mawanga wakuda, yeretsani kamangidwe ka aloyi, ndi Kuwonjezera cerium kwambiri bwino mphamvu ndi kuuma aloyi, ndipo anatsimikiza kuti akadakwanitsira Kuwonjezera kuchuluka kwa cerium m'nkhalango malata mkuwa ndi 0,1% -0.15% , amene bwino bwino mabuku ntchito aloyi nkhalango malata mkuwa, ndi kuimba moyo utumiki wa zinthu zamkuwa aloyi.
Kulimba kwa ingot kwa tin phosphor bronze ndi ubale pakati pa kulimba kwamphamvu ndi kutalika kwa zitsanzo zamapepala ndi zomwe zili mu cerium.Mphamvu ndi kuuma kwa tini phosphor mkuwa kudzawonjezeka ndi kuwonjezeka kwa cerium wa mankhwala, koma pamene cerium okhutira kuposa 0,125%, mphamvu ndi kuuma mankhwala sizidzawonjezeka kwambiri;elongation imawonjezeka ndi zomwe zili mu cerium.Kuwonjezeka kwa voliyumu kunachepa pang'ono.Poganizira kusintha mawotchi zimatha aloyi, momwe akadakwanitsira cerium zili malata phosphor mkuwa ndi 0.1% -0.15%.Ngati cerium ili pamwamba kwambiri, pulasitiki ya alloy idzachepa kwambiri;ngati zomwe zili mu cerium ndizochepa kwambiri, mphamvu yolimbikitsa ya zinthu zosawerengeka zapadziko lapansi pa alloy sizingakhale zofunikira.
