Impembelelo enenzuzo yomhlaba onqabileyo kwizinto zetsimbi ezingenayo i-ferrous ibonakala kakhulu kwii-alloys ze-magnesium. Ayipheleli nje ekuqulunqeni iintlobo zengxubevange ye-Mg-RE, kodwa ibe nefuthe elicacileyo kwiMg-Al, iMg-Zn kunye nezinye iinkqubo zealloyi. Indima yayo ephambili yile ilandelayo:
1. Sula iinkozo
Ii-lygs ezifanelekileyo zomhlaba ezinqabileyo zinokucokisa iinkozo ze-magnesium kunye ne-magnesium alloys. Eyokuqala kukusulungekisa okuziinkozo kokutyhidiweyo. Indlela yokuphosa ilungiselelo lezinto ezinqabileyo zomhlaba zokucokisa i-magnesium alloy ayisosenzo se-nuclei ene-heterogeneous. Umatshini wokucokisa ukutya okuziinkozo okucokisekileyo kwe-magnesium kunye ne-magnesium alloy grain sinofs yezinto ezinqabileyo zomhlaba kukwanda kokupholisa okugqithisileyo kumda wokusika wecrystallization. Okwesibini kukuthintela i-recrystallization kunye nokukhula kweenkozo kwinkqubo yokushisa ukushisa kunye nenkqubo yokukhupha.
2. Ukucoca kunyibilika
Izinto zomhlaba ezinqabileyo zinobudlelwane obukhulu kunye nokurhawuzelelwa kune-magnesium kunye neoksijini, ngoko zinokufakwa kwi-Rare Earth oxides ezisabela nge-Mgo kunye nezinye ii-oxides ekunyibilikeni kwaye zisuse i-oxidizing. Idibana nehydrogen kunye nomphunga wamanzi ekunyibilikeni, ivelise okanye iioksidi zomhlaba ezinqabileyo ezifikelela kwiinjongo zokukhutshwa kweoksijini. Kunye kunokongeza ukunyibilika okunyibilikayo kunye nokunciphisa ukubuna okubumbileyo, inkqubela phambili yokulunga.
3. Amandla engxubevange yobushushu begumbi
Uninzi lwezinto ezinqabileyo zomhlaba kwi-magnesium zinenqanaba elikhulu lokunyibilika okuqinileyo, kwaye ngokuhla kweqondo lobushushu kukho utshintsho olubalulekileyo kwiqondo lokunyibilika, ngoko ke izinto ezinqabileyo zomhlaba ukongeza kokomeleza okunyibilikayo okuqinileyo, kuseyinto eluncedo yokuqinisa ukwaluphala. ye-magnesium alloy, ezinye iikhompawundi zomhlaba ezinqabileyo kunye nokuqiniswa kwe-dispersive.
4. Ukuzinza kwe-Thermal ye-progressive alloy mechanical imisebenzi
Izinto zomhlaba ezinqabileyo zezona zinto ziluncedo kakhulu zokuxhathisa ubushushu be-magnesium alloy, zinokuphucula kakhulu amandla obushushu obuphezulu be-Mg ingxubevange kunye nobushushu obuphezulu bokuxhathisa, izizathu zazo zininzi: i-coefficient yomhlaba enqabileyo kwi-magnesium incinci, inokucotha. Ukuhla kwenkqubo yokuhlaziya kunye nenkqubela phambili yobushushu bokuhlaziya, yongeza umphumo wokwaluphala kunye nesigaba esichithwayo sokuzinza kwe-thermal, I-compound yomhlaba enqabileyo enendawo yokunyibilika ephezulu ikhupha ikristale. umda, uthintela ukungahambi kakuhle kwentshukumo, kwaye uqhubela phambili ukuxhathisa kweqondo lokushisa eliphezulu.
5. I-Progressive alloy corrosion resistance
Ngenxa yokuba i-melt iyahlanjululwa, imiphumo eyingozi yentsimbi engcolileyo, njl.
