Ti-6Al-4V Titanium Piping Thiab Tubing

Kev tiv thaiv corrosion rau Titanium 6-4 ELI feem ntau zoo heev. Qee lub sij hawm cov hlau yog raug rau kub ntsev kev nyuaj siab corrosion cracking. Qhov kev pheej hmoo no tuaj yeem txo qis, txawm li cas los xij, nrog kev ua kom raug.

Ti-6Al-4V ELI qhia txog ntu me me hardenability, yog li kev kho cua sov feem ntau yog siv rau hauv cov mob annealed (ntau yam kev kho mob hauv qab no). Ntau dua tensile zog, txawm li cas los xij, tuaj yeem tau los ntawm kev kho cua sov ua raws li kev laus. Thaum lub zog tau txais los ntawm qhov no, nws yog, txawm li cas los xij, ntawm tus nqi ntawm pob txha toughness.

Ti-6Al-4V Titanium Piping thiab Tubing

Thaum annealing 6-4 Titanium ELI, Mill anneal (MA) yog lub hom phiaj dav dav siv. Qhov no tshwm sim rau tag nrho cov khoom zeb. Ib tug yuav tsum paub hais tias nws yuav tsis yog ib tug tag nrho anneal, txawm li cas los xij, thiab tej zaum yuav muaj qhov kub, txias lossis sov ua haujlwm hauv cov khoom ua haujlwm hnyav xws li ntawv. Duplex anneal thiab triplex anneal kuj tseem siv tau rau kev txhim kho creep resistance thiab recrystallization anneal (RA) thiab beta anneal (BA) yog siv los txhim kho pob txha toughness. Thaum kawg, Beta annealing yuav tsum tau ua kom siab tshaj qhov beta transus kub.

Thaum ua cov nag lossis daus hardening, kev kho kev daws teeb meem thiab kev laus (STA) tuaj yeem ua rau muaj ntau theem ntawm lub zog thiab ductility, nyob ntawm lub voj voog STA thiab cov seem loj. Tsis tas li ntawd, kev kho kev daws teeb meem thiab kev laus dhau (STOA) tuaj yeem ua rau qee qhov nce hauv lub zog, nrog kev txaus siab toughness thiab seem stability.
