Tšusumetso ea litšepe tse sa tšoaneng ka thepa le malleability ea tšepe

Litšepe ke thermoplastic 'me li ka hatelloa ha li futhumala (litšepe tse fapaneng li hloka mocheso o fapaneng).Sena kee bitsoang malleability.
Malleability/ Bokgoni ba tshepe ya ho fetola sebopeho ntle le ho petsoha nakong ya ho sebetsa ka kgatello.E kenyelletsa bokhoni ba ho etsa hamore forging, rolling, otlolla, extrusion, joalo-joalo libakeng tse chesang kapa tse batang.The malleability haholo-holo e amanang le metsoako ea lik'hemik'hale tsa thepa ea tšepe.

1. Titanium e na le phello efe ho thepa le ho senyeha hatshepe?
Titanium e hloekisa lijo-thollo tsa tšepe.Fokotsa kutloisiso e feteletseng ea tšepe ea tšepe.Lintho tse entsoeng ka titanium ka tšepe ha lia lokela ho ba tse ngata haholo, ha carbon content e feta makhetlo a 4, e ka fokotsa mocheso o phahameng oa polasetiki oa tšepe, o sa lokelang ho etsoa.
Titanium e na le khanyetso e ntle ea kutu, e eketsa titanium hots'epe e sa beng le mabali(e kenyellelitsoe ho AISI321 tšepe) e ka felisa kapa ea fokotsa ts'ebetso ea "intercrystalline corrosion".

2. Vanadium e na le phello efe ho thepa le ho senyeha ha tšepe?Vanadium e eketsa matla, ho tiea le ho thatafala ha tšepe.
Vanadium e na le tšekamelo e matla ea ho theha li-carbides le phello e matla ho ntlafatseng lijo-thollo.Vanadium e ka fokotsa kutloelo-bohloko ea tšepe haholo, ea eketsa mocheso o phahameng oa tšepe ea tšepe, 'me kahoo ea ntlafatsa ho sebetsa ha tšepe.
Vanadium ka ho qhibiliha ha tšepe e lekanyelitsoe, hang ho feta e tla fumana sebopeho sa kristale e mahoashe, e le hore taba ea ho theoha ha polasetiki, khanyetso ea deformation e eketsehe.

3. Sebabole se na le phello efe ho thepa le ho fokola hatshepe?
Sebabole ke ntho e kotsi ka tšepe, 'me kotsi e ka sehloohong ke brittleness e chesang eatshepe.Ho qhibiliha ha sebabole ka har'a tharollo e tiileng ke ntho e nyenyane haholo, 'me e kopana le likarolo tse ling ho etsa li-inclusions tse kang FeS, MnS, NiS, joalo-joalo FeS ke eona e kotsi ka ho fetisisa,' me FeS e etsa li-cokuns tse nang le Fe kapa FeO, tse qhibilihisang ka 910. ~ 985C le ho aba moeling oa lijo-thollo ka marang-rang, ho fokotsa haholo polasetiki ea tšepe le ho baka mocheso oa mocheso.
Manganese e felisa brittleness e chesang.Hobane manganese le sebabole li na le kamano e kholo, sebabole ka tšepe se etsa MnS e nang le ntlha e phahameng ea ho qhibiliha sebakeng sa FeS.

4. Phosphorous e na le phello efe ho thepa le ho se khonehe hatshepe?
Phosphorus le eona ke ntho e kotsi tšepeng.Esita le haeba dikahare tsa phosphorus ka tšepe e le likete tse 'maloa feela, brittleness ea tšepe e tla eketseha ka lebaka la pula ea brittle compound FegP, haholo-holo mocheso o tlaase, o fellang ka "brittle e batang".Kahoo fokotsa palo ea phosphorus.
Phosphorus e fokotsa ho cheseha hatshepe, 'me ho bonolo ho hlahisa mapetsong a ho cheselletsa ha e feta moeli.Phosphorus e ka ntlafatsa ts'ebetso ea ho itšeha, kahoo litaba tsa phosphorus li ka eketsoa ka tšepe pele ho seha habonolo.
