Titanium alloysmuaj cov khoom zoo heev, suav nrog qhov ntom ntom (4.51 g / cm³, 57% ntawm cov hlau), lub zog siab (lub zog tensile 680-}}1180 MPa), siab hardness (30-40 HRC), dav kev khiav hauj lwm kub ntau yam (siab kub 600 degree, qis kub -253 degree), zoo corrosion kuj, tsis-sib nqus hlau nplaum, kev ua tau zoo thiab tsis tshua muaj thermal conductivity.
Nyob rau hauv xyoo tas los no, qhov kev thov rau titanium alloys hauv aerospace, marine engineering, shipbuilding, automotive, chemical, electronics, kev kho mob, thiab fais fab kev lag luam tau nce. Qhov kev xav tau ntawm kev lag luam thoob plaws no yog maj nrawm rau kev txhim kho ntawm titanium alloy forging txheej txheem thiab thev naus laus zis.
Hom kev kho cua sov rau Titanium Alloys
Feem ntau siv cov kev kho cua sov rau titanium alloys yog annealing, kev kho tshuaj, thiab kev laus kev kho mob. Annealing yog tsim rau txhua hom titanium alloys, feem ntau kom tau txais cov khoom siv kho kom zoo, txo kev ntxhov siab, txhim kho plasticity, thiab ruaj khov microstructure. Kev kho mob thiab kev laus kev kho mob yog lub ntsiab lus tseem ceeb ntawm kev ntxiv dag zog rau titanium alloys.
Kev ntxhov siab -Nyob rau hauv kev ntxhov siab
Qhov kub annealing yog 100-250℃qis dua qhov kub ntawm recrystallization. Lub hom phiaj yog txhawm rau tshem tawm lossis txo cov kev ntxhov siab sab hauv tsim thaum lub sijhawm ua haujlwm, tiv thaiv thiab txo qis deformation.
Tag Nrho Annealing
Kuj tseem hu ua: Recrystallization Annealing
Lub annealing kub yog ze rau lub recrystallization kub thiab lub transformation point. Recrystallization feem ntau tshwm sim thaum lub sij hawm annealing txheej txheem, thiab qhov kub thiab txias yog siab tshaj cov alloy lub recrystallization kub. Lub hom phiaj yog los txo cov hardness, txhim kho plasticity, stabilize lub microstructure, thiab txhim kho kev ua tau zoo.
Ob chav Annealing suav nrog ob txheej txheem annealing: siab-kub thiab qis-kub annealing, ua raws li huab cua txias. Qhov siab -kub annealing kub yog 20-160℃hauv qab ntawm qhov kev hloov pauv, thiab qhov ntsuas kub qis qis yog 300-500℃hauv qab ntawm theem hloov pauv. Lub hom phiaj yog txhawm rau txhim kho kev ruaj ntseg ntawm microstructure thiab cov khoom.
Isothermal Annealing
Ib daim ntawv tshwj xeeb ntawm ob chav annealing Ua ntej, qhov kub yog rhuab mus rau 20-160℃hauv qab ntawm qhov kev hloov pauv, tuav ntawm qhov kub thiab txias, tom qab ntawd hloov mus rau qhov kub qis (600-}}650 degree) rau tuav, thiab thaum kawg cua txias rau chav sov. Haum rau titanium alloys nrog high-stabilizing cov ntsiab lus, qeeb txias yog ua hauj lwm kom tso cai rau kom tiav decomposition ntawm theem. Lub hom phiaj yog kom tau txais kev ruaj khov microstructure.
Kev kho mob
Cov cua sov ua haujlwm saum toj ntawm + ob- theem hloov pauv kub tab sis qis dua qhov hloov pauv (28-83℃). Hauv cov xwm txheej tshwj xeeb, cua sov saum toj ntawm qhov kev hloov pauv kuj tseem ua tau, ua raws li quenching. Lub hom phiaj yog kom tau txais qhov feem ntau ntawm cov hnub nyoog-hardening metastable theem. Kev laus Kev Kho Mob Feem ntau, cov cua sov ua haujlwm ntawm 425-650 degree. Kev laus kub thiab lub sijhawm tuaj yeem txiav txim siab raws li qhov kev laus tawv tawv nkhaus. Lub hom phiaj yog los txhawb qhov decomposition lossis nag lossis daus ntawm cov theem metastable, yog li ua kom lub zog alloy.
