1. Nws muaj cov nyhuv ntawm kev laus los nag thiab ntxiv dag zog. Lub siab solubility ntawm lub ntiaj teb tsis tshua muaj cov ntsiab lus magnesium txo qis thaum qhov kub thiab txias. Thaum cov khoom siv ib-theem ntawm qhov kub thiab txias yog txias, ib qho kev daws teeb meem tsis ruaj khov supersaturated yog tsim. Tom qab lub sij hawm ntev ntawm kev laus, nplua thiab dispersed khoom daws yog tsim. ntawm nag lossis daus theem. Kev sib cuam tshuam ntawm cov theem precipitated thiab dislocations nce lub zog ntawm cov hlau.
2. Cov nyhuv ntawm cov nplua nplej ntxiv dag zog. Qhov kev nplua nuj ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb nyob rau pem hauv ntej ntawm cov khoom-kua interface ua rau supercooling ntawm cov khoom, thiab ib cheeb tsam nucleation tshiab yog tsim nyob rau hauv cheeb tsam supercooling los tsim cov pob zeb zoo equiaxed. Tsis tas li ntawd, qhov kev nplua nuj ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb tiv thaiv kev loj hlob ntawm -Mg nplej. ntxiv txhawb cov nplej refinement.
3. Melt purification nyhuv. Cov ntsiab lus tsis tshua muaj hauv ntiaj teb tuaj yeem tshem tawm hydrogen, oxygen, sulfur, hlau thiab suav nrog hauv magnesium alloy melts, ua tiav cov teebmeem ntawm degassing, refining thiab purifying lub yaj.
4. Melt tiv thaiv nyhuv. Magnesium alloys yooj yim heev rau oxidize thiab hlawv thaum lub sij hawm smelting. Kev tsim khoom ntawm magnesium alloys feem ntau yog smelted los ntawm flux npog lossis roj tiv thaiv txoj kev, tab sis ob qho tib si muaj ntau yam tsis txaus. Yog tias qhov kub thiab txias ntawm magnesium alloy yaj nws tus kheej tuaj yeem nce ntxiv, nws tuaj yeem ua tiav magnesium alloy Direct smelting nyob rau hauv huab cua yog qhov tseem ceeb rau kev txhawb nqa ntxiv thiab kev siv magnesium alloys. Lub ntiaj teb tsis tshua muaj zog ntawm Magnesium alloy yaj, uas tuaj yeem ua rau qhov kev sib ze ntawm cov cua nab kuab thiab qhov kub thiab txias .
