Cov tshuaj, lub cev, thiab txhua yam khoom ntawm titanium raj siv rau GR1 pa.

1, qhov ceev ntawm titanium hlau yog 4.51g / cm3, siab dua txhuas thiab qis dua hlau, tooj liab, npib tsib xee, tab sis lub zog tshwj xeeb yog nyob rau hauv thawj hlau. Lub melting point ntawm titanium 1660 ± 10 degree. Kub taw tes 3287 degree. Lub valence +2, +3 thiab +4. Nws muaj kev tiv thaiv corrosion zoo thiab tsis cuam tshuam los ntawm huab cua thiab dej hiav txwv. Nyob rau hauv chav tsev kub, nws yuav tsis corroded los ntawm dilute hydrochloric acid, dilute sulfuric acid, nitric acid los yog dilute alkali tov; tsuas yog hydrofluoric acid, kub concentrated hydrochloric acid thiab concentrated sulfuric acid tuaj yeem ua haujlwm.

2, Titanium hlau plua plav yog tawg thiab yuav kub hnyiab thiab tawg thaum nws ntsib cua sov, qhib nplaim taws lossis tshuaj tiv thaiv. Nws cov hmoov tshuaj ua haujlwm siab heev, nyob rau hauv cov huab cua tuaj yeem ua rau spontaneous combustion. Titanium hlau tsis tsuas yog hlawv hauv huab cua, tab sis kuj nyob rau hauv carbon dioxide los yog nitrogen. Nws yog ib qho yooj yim los ua ke nrog halogen, oxygen, sulfur thiab nitrogen ntawm qhov kub thiab txias. Thaum titanium hlawv, siv cov hmoov qhuav thiab cov xuab zeb qhuav los tua hluav taws. nruj me ntsis txwv tsis pub dej, ua npuas ncauj, carbon dioxide extinguishing. Thaum tshav kub kub los yog khaus combustion, dej extinguishing yuav ua rau tawg.

3, titanium kev ua haujlwm loj heev, tsis yog tsuas yog nyob rau hauv lub xeev yaj, txawm tias nyob rau hauv lub xeev siab tshaj 400 degree, tab sis kuj yooj yim kis los ntawm dej, huab cua, roj thiab oxides, nqus oxygen, nitrogen, hydrogen, carbon thiab thiaj li nyob. Yog li txo cov plasticity thiab toughness ntawm welded pob qij txha thiab tawg. Hlau cov pa phem ntawm titanium feem ntau yog nyob rau hauv vuam thiab cua sov txheej txheem los tsim titanium-hlau tebchaw, txo cov neeg kho tshuab zog ntawm welds thiab corrosion kuj; Nyob rau hauv lub luag hauj lwm ntawm corrosive media, nto hlau hais yuav ua rau pitting thiab hydrogen embrittlement.

4, lub coefficient ntawm linear expansion ntawm titanium yog hais txog 2/3 ntawm carbon steel, sib npaug rau 50% ntawm stainless hlau. Titanium lub thermal conductivity yog 4.5 npaug me dua li ntawm cov hlau thiab qis dua cov hlau tsis muaj steel.

5, titanium muaj qhov ua kom pom tseeb, nws qhov kev tiv thaiv yog stainless hlau thaum txias molding 2 mus rau 3 zaug. Thiab stainless hlau li yooj yim rau lo. Titanium lub zog tensile txo qis thaum kub nce. Thaum qhov kub nce mus txog 250 degrees nws lub zog tensile tsuas yog 50% ntawm chav tsev kub.

6, kev lag luam ntshiab titanium plasticity thiab kub muaj kev sib raug zoo tshwj xeeb, chav tsev kub rau 200. C, tus txheeb ze elongation ntawm titanium nce, thiab tom qab ntawd txuas ntxiv nce qhov kub thiab txias pib poob. Nyob rau hauv 450 ~ 500 thaum tus txheeb ze elongation mus txog qhov tsawg kawg nkaus thiab tom qab ntawd nce ho. Yog li ntawd, kev siv kub tsis tshaj 350 degree.
