Cov nyhuv ntawm Cerium ntawm Cov Khoom ntawm Tin Phosphor Bronze Alloy

Cov kev sim tau ua pov thawj qhov cuam tshuam ntawm cerium ntawm microstructure ntawm lubtin-phosphor tooj liabQSn7-0.2 alloy uas tau raug cam khwb cia, homogenized thiab recrystallized.Lub mesh ua finer, thiab cov qauv nplej yog pom tseeb refined tom qab deformation annealing.Ntxiv ib qho me me ntawm lub ntiaj teb uas tsis tshua muaj cerium tuaj yeem ntxuav cov teeb meem tsis zoo hauv cov hlau los yog tshem tawm nws cov txiaj ntsig tsis zoo, thiab tuaj yeem sib xyaw nrog tooj liab los ua CuCeP intermetallic compounds, uas tau tawg mus rau hauv cov ciam teb lossis cov nplej.Cov theem thib ob, uas tau muab faib rau hauv cov xim dub me me, ua kom zoo dua cov qauv hlau, thiab qhov sib ntxiv ntawm cerium tseem txhim kho lub zog thiab hardness ntawm cov hlau, thiab nws tau txiav txim siab tias qhov zoo tshaj plaws ntxiv ntawm cerium nyob rau hauv hav zoov tin bronze yog 0.1% -0.15%, uas zoo txhim kho cov kev ua tau zoo ntawm cov hav zoov tin bronze alloy cov khoom siv thiab kev pab cuam lub neej.
Ingot hardness ntawm tin phosphor bronze thiab kev sib raug zoo ntawm tensile zog thiab elongation ntawm daim ntawv specimens thiab cerium cov ntsiab lus.Lub zog thiab hardness ntawm tin phosphor bronze yuav nce nrog nce ntawm cov ntsiab lus cerium ntawm cov khoom, tab sis thaum cov ntsiab lus cerium tshaj 0.125%, lub zog thiab hardness ntawm cov khoom yuav tsis nce ho;elongation nce nrog cov ntsiab lus cerium.Qhov nce hauv ntim tau qis me ntsis.Xav txog kev txhim kho cov khoom siv ntawm cov hlau, qhov zoo tshaj plaws cerium cov ntsiab lus ntawm tin phosphor bronze yog 0.1% -0.15%.Yog tias cov ntsiab lus cerium siab dhau lawm, cov yas ntawm cov hlau yuav txo qis ntau dhau;Yog hais tias cov ntsiab lus cerium tsawg dhau lawm, qhov kev txhawb zog ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb ntawm cov hlau yuav tsis tseem ceeb.
