Sharaxaada wax soo saarka
● Naxdinta nuugista.nuugista shoogga ee birta ductile waxay ka fiican tahay tan kabka cawl.Markasta oo uu sareeyo heerka spheroidization, waa yaraanta nuugista naxdinta.Marka heerkulku kor u kaco, nuugista naxdinta leh ee kabka cawl ayaa hoos u dhacda, laakiin saamaynta birta ductile waa yar tahay.
● goynta waxqabadka.Birta xuubka ayaa ka kooban graphite badan, kaas oo door ka ciyaara jarista saliidda.Sidaa darteed, iska caabbinta goynta birta ductile waxay ka hooseysaa tan birta, iyo xawaaraha goynta ayaa ka sarreeya.
● Weldability.Birta birta ah lama alxan karo, kaliya waxa lagu hagaajiyaa alxanka.Marka waxa ku jira daawaynta magnesium ee naadirka ah ee dhulka ee birta ductile ay sarreyso, way fududahay in la soo saaro afka cad ama qaab-dhismeedka martensitic si uu u sameeyo diiqad gudaha ah iyo dildilaaca aagga u dhow alxanka.
● U adkaysiga kulaylka.Garaafka ku jira birta ductile ayaa midba midka kale ka soocaa, kaas oo xannibaya faafinta ogsijiinta heerkulka sare marka loo eego birta cawlan.Sidaa darteed, caabbinta oksaydhka iyo caabbinta korriinka ee birta ductile waxay ka fiican tahay kuwa birta cawlan iyo birta malleable.Iska caabbinta korriinka heerkulka sare ee birta ductile ferritic ayaa ka fiican tan birta ductile pearlitic.Kordhinta maadada silikoon ama aluminiumku waxay wanaajin kartaa iska caabbinta oksaydhka iyo iska caabbinta kulaylka birta ductile.
● Iska caabbinta daxalka.Birta xuubka iyo birta cawl leh waxay leeyihiin iska caabin daxaleed wanaagsan oo ku jira xalalka alkaline, iyo iska caabinta daxalka ee birta ductile ee organics, sulfides, iyo biraha dhalaalay (barta dhalaalka hoose) waxay la mid tahay tan birta cawlan.
● Iska caabbinta nabarrada.Birta birta ah waa wax fiican oo u adkaysta xidhashada iyo xidhashada, adkaysigeeduna waxa uu ka fiican yahay ka birta cawlan, birta kaarboonka iyo xataa birta daawaha hoose oo isku mid ah.
● (1) Saliid iyo xidhashada caabbinta, caabbinta xidhashada birta ductile ayaa ka fiican tan kabka cawl
● (2) Xiro-xiran, birta ductile waxay sidoo kale leedahay codsiyo gaar ah oo hoos yimaada xaaladaha xirashada xoqidda.Si kastaba ha ahaatee, marka la barbar dhigo birta kabka cad iyo birta daawaha hoose, caabbinta xirashada ee birta ductile caadiga ah ma aha mid aad u wanaagsan, kaliya birta ductile birta ah ama Alloy Bainite ductile birta ayaa leh iska caabin wanaagsan.
Aagga Codsiga
Waxaa loo adeegsadaa gaadiidka noocyada kala duwan ee biyaha (tusaale: biyaha ceeriin, biyaha la daweeyay, dib u isticmaalka biyaha, iwm.)
