Iintsimbi zi-thermoplastic kwaye zinokucinezelwa xa zishushu (iintsimbi ezahlukeneyo zifuna amaqondo okushisa ahlukeneyo). Yi leebizwa ngokuba yimalleability.
I-malleability ukukwazi kwezinto zetsimbi ukutshintsha imilo ngaphandle kokuqhekeka ngexesha lokusebenza koxinzelelo. Kubandakanya ukukwazi ukwenza isando sokubumba, ukuqengqeleka, ukolula, ukukhupha, njl. kwiindawo ezishushu okanye ezibandayo. I-malleability ikakhulu inxulumene nokwakheka kweekhemikhali zezinto zetsimbi.
1. Yiyiphi impembelelo enayo i-titanium kwiipropati kunye nokuthambile kweintsimbi?
I-Titanium icokisa ukhozo lwentsimbi. Nciphisa ubushushu bobushushu bentsimbi. Umxholo we-titanium kwintsimbi akufanele ube mkhulu kakhulu, xa umxholo wekhabhoni ungaphezu kwamaxesha angama-4, unokunciphisa ubushushu obuphezulu beplastiki yensimbi, engafanelekanga ukwenza.
I-Titanium inokumelana ne-corrosion, yongeza i-titanium kuyoyenziwe ngentsimbi eshayinayo(eyongeziweyo kwintsimbi ye-AISI321) inokuphelisa okanye ukunciphisa i-intercrystalline corrosion phenomenon.
2. I-vanadium inefuthe lini kwiipropati kunye ne-malleability yensimbi? I-Vanadium ikwandisa amandla, ukuqina kunye nokuqina kwentsimbi.
I-Vanadium inomdla oqinileyo wokwenza i-carbides kunye nefuthe elinamandla ekuphuculeni okusanhlamvu. I-Vanadium inokunciphisa kakhulu uvakalelo olugqithisiweyo lwentsimbi, inyuse ubushushu obuphezulu beplastiki yentsimbi, kwaye ngaloo ndlela iphucule ukunyibilika kwentsimbi.
Vanadium ekunyibilikeni kwentsimbi kulinganiselwe, kanye ngaphezu uya kufumana isakhiwo crystal erhabaxa, ukuze imeko ukuhla zeplastiki, ukumelana deformation anda.
3. Yintoni umphumo wesulfure kwiipropati kunye nokungabi nangxaki yeintsimbi?
I-Sulfur yinto eyingozi kwintsimbi, kwaye eyona nto iyingozi kakhulu yi-brittleness eshushuintsimbi. I-solubility yesulfure kwisisombululo esiqinileyo sincinci kakhulu, kwaye idibanisa kunye nezinye izinto ukuze zenze ukubandakanywa okufana ne-FeS, i-MnS, i-NiS, njl njl. I-FeS yeyona nto inobungozi, kwaye i-FeS yenza i-cokuns nge-Fe okanye i-FeO, enyibilika kwi-910. ~ 985C kwaye isasaza kumda wengqolowa kumnatha womnatha, ukunciphisa kakhulu iplastiki yentsimbi kunye nokubangela ukufudumala kwe-thermal.
IManganese iphelisa ubuqhophololo obushushu. Ngenxa yokuba imanganese kunye nesalfure zinobudlelwane obukhulu, isulfure kwintsimbi yenza i-MnS enendawo yokunyibilika ephezulu endaweni ye-FeS.
4. Iphosphorus inefuthe lini kwiipropati kunye nokululaintsimbi?
Iphosphorus ikwayinto eyingozi kwintsimbi. Nokuba umxholo we-phosphorus kwintsimbi ungamawaka ambalwa kuphela, ukunyanzeliswa kwentsimbi kuya kwanda ngenxa yemvula ye-brittle compound FegP, ngokukodwa kwiqondo lokushisa eliphantsi, elibangela "i-cold brittle". Ngoko nciphisa inani le-phosphorus.
Phosphorus yehlisa ukuwelda kweintsimbi, kwaye kulula ukuvelisa i-welding cracks xa idlula umda. I-Phosphorus inokuphucula ukusebenza kokusika, ngoko umxholo we-phosphorus unokunyuswa kwintsimbi ngaphambi kokusika lula.
