Dab tsi yog titanium hlau?

Cov hlau uas muaj kev sib xyaw ntawm titanium thiab ntxiv alloying ntsiab xws li npib tsib xee, molybdenum, chromium, txhuas, vanadium, tooj liab, thiab carbon yog hu ua titanium hlau, los yog titanium alloy hlau. Hlau lub cev thiab txhua yam zoo, xws li lub zog, hardness, tawg toughness, thiab high-temperature creep resistance, tuaj yeem txhim kho los ntawm kev ntxiv titanium ua ib qho khoom siv alloying.

titanium steel yog dab tsi?

Thawj hlau hauvtitanium hlauyog hlau, uas tsim lub hauv paus matrix ntawm alloy. Tus nqi ntawm cov hlau txawv tab sis feem ntau yog nyob ib ncig ntawm 85-95 feem pua ​​ntawm qhov hnyav. Titanium tau ntxiv txog li ntawm 5-15 feem pua ​​​​los muab cov khoom muaj txiaj ntsig. Lwm cov ntsiab lus alloying xws li npib tsib xee, molybdenum, chromium, vanadium, tooj liab, aluminium, thiab carbon kuj yuav raug ntxiv rau me me kom txuas ntxiv cov khoom thiab cov yam ntxwv ntawm cov hlau.

Kev tsim cov titanium hlau pib nrog melting hlau thiab lwm yam hlau ua ke nyob rau hauv ib tug hluav taws xob arc rauv los yog ib tug induction rauv. Tom qab ntawd cov hlau molten yog refined thiab alloying ntsiab xws li titanium, npib tsib xee, chromium, molybdenum yog ntxiv rau cov nqi meej. Cov sib tov yog ces cam khwb cia rau hauv ingots los yog nruam nrum rau hauv billets rau ntxiv ua. Cov hlau tom qab ntawd ua rau kub dov, kho cua sov, thiab ua haujlwm txias los tsim cov khoom siv titanium kawg.

Dab tsi yog titanium steel siv rau?

Titanium steel pom siv nyob rau hauv ntau yam kev siv tseem ceeb uas yuav tsum muaj lub zog siab, qhov hnyav, thiab kev tiv thaiv corrosion zoo. Qee qhov kev siv loj ntawm titanium steels yog:

Aerospace kev lag luam: Siv nyob rau hauv aircraft structural qhov chaw xws li tis, fuselages, tsaws gears qhov twg lub zog thiab tsis tshua muaj ceeb thawj. Lub siab tshwj xeeb lub zog ntawm titanium steel pab ua kom muaj peev xwm them taus thiab roj efficiency.

Cov ntawv thov kev lag luam: Siv nyob rau hauv chav thiab roj turbines rau kev tsim hluav taws xob. Lub siab kub lub zog tso cai rau cov khoom xws li cov hniav, discs, casings kom tiv taus qhov chaw huab cua. Kuj tseem siv nyob rau hauv cov cua kub exchangers thiab condensers nyob rau hauv fais fab nroj tsuag.

Automotive kev lag luam: Siv nyob rau hauv qhov chaw xws li txuas rods, crankshafts, springs, fasteners, tso pa tawm qhov twg lub zog ntawm siab kub yuav tsum tau. Lub siab qaug zog muaj nuj nqis.

Kev lag luam tshuaj lom neeg: Vim muaj kev tiv thaiv corrosion zoo, titanium steels yog siv rau hauv cov tshuaj reactors, tshav kub exchangers, li qub, twj rau tuav corrosive ib puag ncig.

Biomedical implants: Lub biocompatibility thiab corrosion kuj tso cai rau siv nyob rau hauv phais kev cog hniav zoo li lub duav thiab lub hauv caug pob qij txha, pob txha daim hlau, screws.

Cov khoom ntaus pob ncaws pob: Cov koom haum ntaus golf, tsheb kauj vab thav duab thiab rims leverage lub zog siab rau qhov hnyav piv thiab qaug zog.

Cov khoom siv ua zaub mov: Nrog zoo corrosion kuj, titanium steels ua tau zoo nyob rau hauv cutlery, siab hlab ntsha, boilers rau zaub mov.

Puas yog titanium steel zoo zoo?

Yog lawm, titanium steel yog suav tias yog cov khoom siv hluav taws xob zoo vim muaj cov khoom zoo hauv qab no:

Lub zog tensile siab - Titanium steels feem ntau muaj lub zog tensile xws li ntawm 700 MPa txog 1300 MPa, siab dua li cov pa hlau. Qhov no tso cai rau tsim cov khoom sib sib zog nqus.

Zoo ductility - Txawm hais tias lub zog siab, titanium steel khaws cov ductility zoo kom tsis txhob ntxov ntxov thaum muaj kev ntxhov siab. Elongation qhov tseem ceeb nyob ntawm 10-25 feem pua ​​ntawm cov titanium alloys feem ntau.

Kev qaug zog zoo heev - Cov kev ntxhov siab tsis zoo ntawm titanium steels tshaj lwm cov hlau alloy, ua rau lawv zoo tagnrho rau kev siv dynamic.

Qhov zoo tshaj plaws corrosion kuj - Titanium zoo heev txhim khu kev tiv thaiv corrosion vim nws cov refractory xwm. Qhov no tso cai rau siv nyob rau hauv ib puag ncig hnyav.

Lub zog kub siab - Titanium steels tswj lawv lub zog thiab nkag mus rau qhov kub txog li 600 degree, tso cai rau kev siv kub.

Tsawg thermal expansion - Lub coefficient ntawm thermal expansion yog yuav luag ib nrab ntawm steels, txo warping thiab thermal qaug zog.

Tsis-sib nqus - Qhov sib ntxiv ntawm titanium tsim cov hlau uas tsis yog hlau nplaum, uas yog qhov tseem ceeb hauv qee qhov kev siv tseem ceeb.

Qhov hwm zoo thiab kev ua tau zoo ntawm titanium steels tuaj ntawm tus nqi siab dua. Txawm li cas los xij, thaum muaj kev cuam tshuam dhau ntawm cov khoom lag luam, cov khoom zoo tshaj plaws feem ntau pom zoo rau tus nqi pib dua.

Puas yog titanium hlau zoo ib yam li stainless hlau?

Tsis yog, titanium hlau thiab stainless hlau yog cov khoom sib txawv kiag li ntawm cov khoom muaj pes tsawg leeg, cov khoom, thiab kev siv. Qhov sib txawv tseem ceeb yog:

Kev sib xyaw: Cov hlau tsis muaj hlau muaj cov qib siab chromium (10-20 feem pua) thiab npib tsib xee (8-20 feem pua) nrog rau cov hlau.Titaniumsteels muaj titanium raws li lub ntsiab alloying tseem ceeb nrog tsawg kawg nkaus ntawm chromium thiab npib tsib xee.

Khoom: Stainless hlau muab lawv lub zog los ntawm cov ntsiab lus chromium siab thiab kev kho cua sov tom qab. titanium steels tau txais lawv lub zog los ntawm titanium ua raws li kev daws teeb meem hauv cov hlau matrix.

Corrosion tsis kam: Stainless hlau nyob ntawm feem ntau ntawm chromium oxide txheej rau corrosion kuj. Titanium steel cia siab rau qhov inertness ntawm titanium los tiv thaiv corrosion.

Lub zog kub siab: Titanium steels khaws lub zog thiab nkag siab txog li 600 degree. Stainless hlau tsis tuaj yeem ua haujlwm siab dua 300-400 degree vim nag lossis daus ntawm nkig theem.

Sib nqus permeability: Stainless hlau yog ferromagnetic vim hlau thiab chromium. Titanium hlau tsis yog hlau nplaum.

Tus nqi: Titanium kim dua li chromium thiab npib tsib xee. Yog li titanium steels raug nqi ntau dua stainless hlau.

Daim ntaub ntawv: Thaum muaj qee qhov sib tshooj, titanium steels feem ntau yog siv qhov ntau dua qhov sib piv ntawm lub zog-rau-qhov hnyav, qaug zog tiv taus lossis kub kub ua haujlwm yog qhov tseem ceeb. Stainless hlau pom dav siv rau kev siv corrosion dav dav.

Hauv cov ntsiab lus, titanium thiab stainless hlau muaj qhov sib txawv kiag li tsim los tsim qee yam khoom thiab kev siv. Titanium steels muab lub zog-rau-qhov hnyav piv tab sis ntawm tus nqi siab dua. Stainless hlau muab zoo heev corrosion kuj ntawm tus nqi qis. Qhov kev xaiv nyob ntawm qhov kev xav tau tshwj xeeb ntawm daim ntawv thov.
