Faa'iidooyinka Isticmaalka Birta Ductile sida Alaabta Valve

Birta ductile waxay ku fiican tahay qalabka waalka, sababtoo ah waxay leedahay faa'iidooyin badan.Beddelka birta, birta ductile waxaa la sameeyay 1949. Kaarboonka ku jira birta shubku waxa uu ka yar yahay 0.3%, halka tan shubka iyo birta ductile ay ugu yaraan tahay 3%.Kaarboonka hooseeya ee birta shubka ah ayaa ka dhigaysa kaarboonka jira sida garaafiga bilaashka ah ee aan samaynin jajabyo.Qaabka dabiiciga ah ee kaarboon ee ku jira birta shubka ah waa jajab garaafka bilaashka ah.In birta ductile, graphite waa qaab nodules halkii ay ka samaysan yihiin sida birta shubka ah.Marka la barbardhigo birta shubka ah iyo birta shubka, birta ductile waxay leedahay sifooyin jidheed oo wanaagsan.Waa qanjidhada wareegsan ee xakameynaya abuurista dildilaaca, sidaas darteed waxay siinaya ductility la xoojiyay oo siinaya daawaha magaceeda.Si kastaba ha ahaatee, jajabka ku jira birta shubka ah waxay keentaa la'aanta ductility birta.Qulqulka ugu fiican waxaa lagu heli karaa matrix ferrite.

Marka la barbardhigo birta kabka ah, birta ductile waxay leedahay faa'iidooyin buuxda xagga xoogga.Xoogga xajinta ee birta ductile waa 60k, halka tan kabka ay tahay kaliya 31k.Awoodda wax-soo-saarka birta ductile waa 40k, laakiin birta kabka ah ma tuso xoogga dhalidda waxayna dillaaci doontaa ugu dambeyntii.

Xoogga birta ductile waxay la mid tahay tan birta shubka ah.Birta xuubka xuubka ayaa leh xoog waxsoosaar sare.Awooda wax-soosaarka ugu hooseeya ee birta ductile waa 40k, halka awoodda wax-soo-saarka birta shubku ay tahay 36k oo keliya.Codsiyada degmada intooda badan, sida biyaha, biyaha cusbada, uumiga, iska caabinta daxalka iyo iska caabinta oksaydhka ee birta ductile ayaa ka sarreeya kuwa birta shubka ah.Birta birta ah waxa kale oo loo yaqaanaa graphite iron spheroidal.Sababtoo ah spheroidal graphite microstructure, birta ductile waxay ka sareysaa birta lagu tuuro gariir qoynta, sidaa darteed waxay aad ugu habboon tahay dhimista walaaca.Sababta muhiimka ah ee loo dooranayo birta ductile sida maaddada waalka waa in ay ka qiimo jaban tahay birta shubka ah.Qiimaha hooseeya ee birta tuubada ah ayaa ka dhigaysa alaabtan mid caan ah.Ka sokow, doorashada birta ductile waxay yarayn kartaa kharashka mashiinka.
