Simbi ndeye thermoplastic uye inogona kudzvanywa kana ichipisa (simbi dzakasiyana dzinoda tembiricha dzakasiyana). Ichi chiinonzi malleability.
Malleability kugona kwesimbi zvinhu kuchinja chimiro pasina kutsemuka panguva yekumanikidza kushanda. Zvinosanganisira kugona kuita sando forging, rolling, stretching, extrusion, etc. munzvimbo dzinopisa kana kutonhora. Iyo malleability inonyanya kuenderana nekemikari yemidziyo yesimbi.

1. Ko titanium ine mhedzisiro yei pazvivakwa uye kusagadzika kwesimbi?
Titanium inonatsa zviyo zvesimbi. Deredza kupisa kwekunzwa kwesimbi. Izvo zviri mukati me titanium musimbi hazvifanirwe kunge zvakawandisa, kana kabhoni yemukati inopfuura ka4, inogona kuderedza kupisa kwakanyanya kwepurasitiki yesimbi, iyo isiri yakanaka yekugadzira.
Titanium ine yakanaka corrosion resistance, ichiwedzera titanium kusimbi isina ngura(yakawedzerwa kune AISI321 simbi) inogona kubvisa kana kuderedza intercrystalline corrosion phenomenon.

2. Chii chinoita kuti vanadium iite pane zvinhu uye kusagadzikana kwesimbi? Vanadium inowedzera simba, kuoma uye kuoma kwesimbi.
Vanadium ine tsika yakasimba yekugadzira carbides uye simba rakasimba pakunatswa kwezviyo. Vanadium inogona kuderedza zvakanyanya kupisa kwekunzwa kwesimbi, kuwedzera tembiricha yepurasitiki yesimbi, uye nekudaro inovandudza kuumbwa kwesimbi.
Vanadium mune iron solubility ishoma, kamwe chete kupfuura ichawana coarse crystal chimiro, kuitira kuti nyaya yekuderera kwepurasitiki, deformation kuramba yakawedzera.

3. Chii chinokonzerwa nesarufa pane zvivakwa uye kusanzwisisika kwesimbi?
Sulfur chinhu chinokuvadza musimbi, uye chikuru kukuvadza ndiko kupisa brittlenesssimbi. Kunyungudika kwesarufa mumushonga wakasimba idiki zvakanyanyisa, uye inobatanidza nezvimwe zvinhu kuti zvigadzire zvinosanganisirwa zvakaita seFeS, MnS, NiS, nezvimwewo. FeS ndiyo inonyanya kukuvadza, uye FeS inoumba cokuns ine Fe kana FeO, iyo inonyunguduka pa910. ~ 985C uye inogovera mumuganhu wezviyo mumambure, ichideredza zvakanyanya plastiki yesimbi uye ichikonzera kupisa kwekupisa.
Manganese inobvisa brittleness inopisa. Nekuti manganese nesarufa zvine hukama hukuru, sarufa iri musimbi inoumba MnS ine nzvimbo yakakwira yekunyungudika pachinzvimbo cheFeS.

4. Ko phosphorous ine mhedzisiro yei pazvivakwa uye kusarongeka kwesimbi?
Phosphorus zvakare chinhu chinokuvadza musimbi. Kunyangwe kana zviri mukati me phosphorus musimbi zvingori zviuru zvishoma, brittleness yesimbi ichawedzera nekuda kwekunaya kwe brittle compound FegP, kunyanya pakupisa kwakadzika, zvichikonzera "kutonhora brittle". Saka kuderedza huwandu hwe phosphorus.
Phosphorus inoderedza weldability yesimbi, uye zviri nyore kugadzira welding mitswe kana ichipfuura muganhu. Phosphorus inogona kuvandudza kushanda kwekucheka, saka zvirimo zve phosphorus zvinogona kuwedzerwa musimbi isati yave nyore kucheka.
