Titanium alloys: cov khoom tseem ceeb rau cov ntawv thov kev ua tau zoo
Titanium, ib qho hlau paub txog nws lub zog zoo kawg nkaus, qis dua qhov hnyav, thiab zoo dua los ua cov khoom tseem ceeb hauv kev lag luam siab. Nws cov cuab yeej tuaj yeem hloov kho ntxiv los ntawm kev ua kom zoo thiab theem manymulation, uas ua rau nws tsis tseem ceeb hauv kev kho mob, kev kho mob, thiab kev siv khoom siv.
Cov theem tseem ceeb thiab cov yam ntxwv
Titanium muaj nyob rau hauv ob lub ntsiab crystalline: tusAlpha ()theem thiab covBeta ()theem. Lub alpha theem yog ruaj khov nyob rau hauv qis dua kub, muab lub zog siab, thaum lub sij hawm beta, nyob rau theem pib, ruaj khov thiab tawv. Qhov kev hloov pauv theem no ua lub luag haujlwm tseem ceeb hauv kev shap cov hlau kev ua tau zoo nyob rau ntau daim ntawv thov.
Alloying rau kev ua tau zoo
Titanium lub zog yog qhov ua tau zoo los ntawm kev sib txuam nrog cov khoom xws liAluminium (AL), Vanadium (V), thiabMolybdenum (mo)Cov. Cov ntsiab lus no ua rau lub alpha theem lossis cov theem beta ntawm kev sib txawv ntawm kev sib txawv, tso cai rau ntau lub zog, muaj txiaj ntsig, thiab tawv. Kev xaiv ua tib zoo ntawm alloy cov ntsiab ua rau kev tsim cov titanium alloys uas yog qhov zoo tagnrho rau cov kev lag luam tshwj xeeb.
Titanium alloy koom
Titanium alloys tau faib ua plaub pawg, txhua tus nrog cov cwj pwm tshwj xeeb ua rau cov ntawv thov sib txawv:
Kev lag luam ntshiab titanium:
Paub txog nws qhov zoo heev corrosion tsis kam, lag luam titanium alloys muaj tsawg heev alloy thiab tau siv hauv kev lag luam xws li kev mob kho mob thiab kev ua haujlwm.
Alpha alloys:
Cov alloys no feem ntau yog feem ntawm alpha theem thiab muab lub zog-kub zog, ua rau lawv zoo tagnrho rau kev siv hauv aerospace thiab kev lag luam tsheb.
Alpha-beta alloys:
Cov feem ntau dav siv titanium alloys, alpha-beta alloys muab txoj kev sib npaug zoo tag nrho ntawm lub zog, ua rau muaj zog, thiab cov ntawv thov siv tsheb.
Beta alloys:
Feem pua ntau dua ntawm Beta theem, cov alloys muaj kev zam lub zog tshwj xeeb, uas yog qhov tseem ceeb rau cov txheej txheem kev lag luam hauv Aerospace kev lag luam.
Cov Ntawv Qhia Tseem Ceeb
Titanium thiab nws cov alloys tau siv hauv ntau cov kev xav tau kev lag luam. Hauvib tug tub rog, Titanium yog ua haujlwm rau cov tswv cuab aircraft, tshuab, thiab tsaws lub zog vim nws qhov kev tawm dag zog lub zog thiab kev tawm tsam rau huab cua sov heev. HauvTsis-Aerospace Sectors, xws li kev kho mob, cov tubrog nkoj, thiab lub zog loj ua rau corrosion thiab biocompatibility ua rau nws zoo tagnrho rau kev phais thiab kev hloov pauv cua sov.
