Cov hlau thiab titanium feem ntau siv cov hlau hauv kev tsim khoom vim lawv lub zog zoo tshaj plaws, hardness thiab lwm yam khoom siv tshuab thiab tshuab.
Hlau yog ib qho alloy ntawm cov hlau thiab carbon thiab carbon, nrog cov ntsiab lus carbon, nrog cov ntsiab lus carbon, nrog rau}. 2% rau 2.1% los ntawm qhov hnyav. Txawm hais tias cov hlau thiab carbon thiab carbon ntau yog cov muab cov tseem ceeb ntawm lwm cov xws li manganese, siosphorus yuav muaj. Muaj ntau hom hlau, categorized cov ntsiab lus raws li cov ntsiab lus carbon, alloy cov ntsiab thiab kev kho cua sov. Cov no suav nrog cov hlau me me, hlau stainless thiab high-zog tsawg-alloy steel. Hlau yog paub txog nws lub zog, durability thiab versatility, uas ua rau nws haum rau ntau cov ntawv thov. Nws cov kev siv npog txhua yam los ntawm kev tsim kho thiab tsheb rau cov cuab yeej thiab cutlery.
Titanium yog cov tshuaj lom neeg lub cim nrog lub cim Ti atomic number ib nrog cov xim silvery, qis ntom ntom, thiab muaj zog. Thaum nws yog muaj zog npaum li hlau, nws yog qhov tsis tshua muaj zog, ua nws cov hlau ntawm kev xaiv rau kev siv lub zog-qhov hnyav piv yog qhov tseem ceeb. Nyob rau hauv nws unalloyed lub xeev, titanium yog muaj zog raws li qee cov hlau tab sis tsis tshua ntom. Thaum txuam nrog lwm cov ntsiab xws li txhuas thiab Vanadium, nws tuaj yeem ua tau lub zog loj. Ob lub ntsiab siv ntawm titanium yog aerospace (dav hlau, chaw tsim khoom, muaj zog, thiab resistant rau corrosion txawm tias thaum kub siab.
I. Cawv ntawm Titanium ntawm microstructure thiab cua sov kho ntawm cov hlau
Titanium thiab nitrogen, oxygen, carbon muaj ib qho muaj zog heev, yog tus neeg saib xyuas zoo thiab muaj cov neeg sawv cev ntawm nitrogen thiab pupbon zoo.
Titanium thiab carbonium compounds (TIC) ua ke yog muaj zog heev, tsuas yog rhuab rau ntau dua 1000 degree yuav tsum tau tiv thaiv cov noob qoob loo me me thiab muab lub luag haujlwm.
(iii) titanium yog ib qho ntawm cov ntsiab lus ferrite-ua, kom cov Austenite theem cheeb tsam yog nqaim. Titanium nyob rau hauv cov kev daws teeb meem los txhim kho qhov nyuaj ntawm cov hlau, thaum lub xub ntiag los txo qhov nyuaj ntawm cov hlau.
④ Thaum titanium cov ntsiab lus mus txog ib tus nqi, nag lossis daus ua kom puas tsuaj tuaj yeem tshwm sim vim yog diffuse nag lossis daus.
Thib ob, muaj tus ntawm titanium ntawm cov khoom siv me me ntawm cov hlau
① Thaum titanium muaj nyob rau hauv cov kev daws teeb meem nyob rau hauv cov ferrite, nws muaj zog, thiab lwm yam, phosphorus, tooj liab, silicon.
Cov nyhuv ntawm titanium ntawm cov cuab yeej cuab tam ntawm cov hlau nyob ntawm daim ntawv uas nws muaj, qhov sib piv ntawm cov ntsiab lus ntawm TI thiab C, thiab txoj kev kho cua sov. Titanium Pawg feem ntawm {{{0}}}}}. 03%}. 03%}}. 03%}.
(iii) titanium txhim kho cov kev ua kom muaj zog thiab cov creep tsis kam.
(iv) titanium muaj kev txhim kho cov nyhuv ntawm cov hlau tawv, tshwj xeeb tshaj yog cov kev cuam tshuam kub tsawg.
Thib peb, Titanium ntawm kev siv lub cev, tshuaj lom neeg thiab txheej txheem ntawm cov hlau cuam tshuam
①①prove qhov kev ruaj ntseg ntawm cov hlau hauv qhov kub siab, siab siab thiab hydrogen.
Titanium tuaj yeem txhim kho cov xeb tsis kam ntawm stainless acid-resistant steel, tshwj xeeb tshaj yog cov ua kom tsis kam cuam tshuam rau kev txhim kho corrosion.
③ Hauv cov hlau tsawg tsawg, thaum cov kev sib piv ntawm Ti thiab C Cov Ntsiab Lus Mus Txog Ntau Tshaj 4.5, nws muaj qhov zoo tsis txaus ntseeg rau cov oxygen, nitrogen thiab carbon yog txhua tus.
(iv) ntxiv Titanium rau cov hlau nrog lub chromium huab hwm coj ntawm 4% {% txhim kho cov hlau ntawm cov hlau kub siab.
Txuas ntxiv ntawm Titanium rau cov hlau tuaj yeem txhawb kev tsim cov txheej txheem Nitrivate, thiab qhov xav tau cov hardness tuaj yeem tau sai dua. Titanium-muaj cov hlau yog hu ua "Cov neeg nitriding nitriding ceev" thiab tuaj yeem siv los tsim cov ntsia hlau siab.
⑥⑥prove veldability ntawm cov roj carbon manganese steel thiab high alloy stainless sodium.
Daim ntawv thov ntawm Titanium hauv cov hlau
①Titanium Pawg feem ntawm ntau dua 0. 025% tuaj yeem suav hais tias yog ib qho kev sib dhos.
② Titanium raws li ib qho kev sib txuam hauv cov hlau tsawg-hlau, cov hlau hluav taws xob kub tsis kam, thiab cov hlau pov tseg, thiab cov hlau pov tseg tau siv dav.
③Titanium tau siv ntau cov ntaub ntawv siab, dhau los ua cov ntaub ntawv tseem ceeb, siv ntau dua ib nrab ntawm lub nkoj dav hlau, xws li tshuab hluav taws xob.
