Izinsimbi ziyi-thermoplastic futhi zingacindezelwa lapho zishiswa (izinsimbi ezihlukene zidinga amazinga okushisa ahlukene). Lokhuokubizwa ngokuthi yi-malleability.
I-Malleability ikhono lensimbi lokushintsha isimo ngaphandle kokuqhekeka ngesikhathi sokusebenza kwengcindezi. Kuhlanganisa ikhono lokwenza isando sokufoja, ukugingqa, ukwelula, ukukhishwa, njll. ezimeni ezishisayo noma ezibandayo. Ukonakala kuhlobene kakhulu nokwakheka kwamakhemikhali ensimbi.

1. I-titanium inamuphi umthelela ezimpahleni nasekusebenzisekeni kalula kwayoinsimbi?
I-Titanium ihluza okusanhlamvu kwensimbi. Yehlisa ukuzwela kokushisa okweqile kwensimbi. Okuqukethwe kwe-titanium ensimbi akufanele kube kuningi kakhulu, lapho okuqukethwe kwekhabhoni kungaphezu kwezikhathi ze-4, kunganciphisa izinga lokushisa eliphakeme le-plasticity yensimbi, engalungile yokubumba.
I-Titanium inokumelana nokugqwala okuhle, yengeza i-titanium kuyoinsimbi engagqwali(engezwe ku-AISI321 steel) ingaqeda noma yehlise i-intercrystalline corrosion phenomenon.

2. Imuphi umphumela i-vanadium enawo ezakhiweni nasekusebenzisekeni kalula kwensimbi? I-Vanadium ikhulisa amandla, ukuqina nokuqina kwensimbi.
I-Vanadium inomkhuba oqinile wokwenza ama-carbides kanye nomthelela oqinile ekucwengeni okusanhlamvu. I-Vanadium inganciphisa kakhulu ukuzwela kokushisa okweqile kwensimbi, ikhulise izinga lokushisa eliphezulu lensimbi yensimbi, ngaleyo ndlela ithuthukise ukusebenziseka kalula kwensimbi.
I-Vanadium e-iron solubility ilinganiselwe, kanye ngaphezu kwalokho izothola isakhiwo se-crystal esimahhadla, ukuze icala lokwehla kwepulasitiki, ukumelana ne-deformation anda.

3. Uyini umphumela wesulfure ezimpahleni nasekusebenzisekeni kalula kweinsimbi?
Isibabule siyinto eyingozi ensimbi, futhi umonakalo omkhulu ukuqina okushisayo kweinsimbi. Ukuncibilika kwesibabule esixazululweni esiqinile kuncane kakhulu, futhi kuhlangana nezinye izakhi ukwenza okufakiwe okufana ne-FeS, MnS, NiS, njll. I-FeS iyingozi kakhulu, futhi i-FeS yenza ama-cokuns ane-Fe noma i-FeO, encibilika ku-910. ~ 985C futhi isakaza emngceleni wokusanhlamvu kunethiwekhi, inciphisa kakhulu ipulasitiki yensimbi futhi ibangele ukufudumala okushisayo.
I-Manganese iqeda ukushisa okushisayo. Ngenxa yokuthi i-manganese nesibabule kunokuhlobana okukhulu, isibabule esisensimbi sakha i-MnS enephoyinti eliphezulu lokuncibilika esikhundleni se-FeS.

4. I-phosphorus inamuphi umthelela ezimpahleni nasekusebenziseni kalulainsimbi?
I-Phosphorus nayo iyisici esiyingozi ensimbi. Ngisho noma okuqukethwe kwe-phosphorus ensimbi kuyizinkulungwane ezimbalwa kuphela, i-brittleness yensimbi izokhula ngenxa yemvula ye-brittle compound FegP, ikakhulukazi ekushiseni okuphansi, okuholela "ekubanda okubandayo". Ngakho nciphisa inani le-phosphorus.
I-Phosphorus inciphisa ukushiselainsimbi, futhi kulula ukukhiqiza imifantu ye-welding lapho idlula umkhawulo. I-Phosphorus ingathuthukisa ukusebenza kokusika, ngakho okuqukethwe kwe-phosphorus kungandiswa ngensimbi ngaphambi kokusika kalula.
