1, Cov txheej txheem txheej txheej: Ntsuas qhov hnyav thiab tawv
Cov ntsiab cai tseem ceeb: tus qauv sib xyaw uas muab sib txuas nrog rigidity thiab yooj
Lub ntsiab lus ntawm laminated Damascus Steel yog kev xyaum thaum ntxov ntawm "cov khoom siv sib xyaw". Hauv kev ua yeeb yam ib txwm ua, cov kws ntaus hlau sib txawv ntxiv tab sis cov khoom siv tsawg dua tshiab Piv txwv li, Niaj hnub ua noj ua mov riam phom li 67 txheej txheem ntawm cov qauv tsim los ntawm vg [}) Ntawm ob sab, 33 txheej yog ua los ntawm 420j2 cov roj carless cov hlau stainless (nrog cov ntsiab lus carbon (nrog cov ntsiab lus carbon (nrog cov ntsiab lus carbon) ntawm 0.3% los txhim kho kev cuam tshuam tsis kam. Qhov no "dag cov pob txha mos mos" tso cai rau cov hniav kom nyob twj ywm hauv kev sib txawv ntawm sab nraud deformation, zam brittle bacture.
Cov me me tshuab hluav taws xob: synergistic nyhuv ntawm carbides thiab seem ntawm lub ausustenite
Hauv lub tshuab tsom, cov hniav ntawm laminated Damascus steel nthuav tawm tshwj xeeb "micro serrated" qauv. Hlau carbide (fe {- c) hauv cov ntoo khaub ncaws zoo, ua rau cov hmoov nplej sib dhos uas sib dhos micro serrations thaum lub sij hawm txiav, ua kom zoo nkauj ua kom zoo nkauj. Cov seem ntawm Austenite (tsis tau siv tshuaj pab tsis tau (tsis tau siv tshuaj pab pawg) thiab cov hlawsite hauv cov theem qis {}} pevium roj ua raws li kev ntxhov siab tawg. Piv txwv li, cov carbon nanotube cov qauv pom nyob hauv Uzi Steel (cov khoom siv uas ua tau ntawm thaum ub hlau) ntxiv txhim kho cov khoom muaj peev xwm tiv thaiv tawg. Qhov kev tsim muaj zog multiphase tso cai rau Laminically Steel los tswj hwm tus kheej nyuaj rau ntawm HRC 60, deb ntawm cov cuab yeej txiav ntawm cov cuab yeej txiav.
Kev Tshawb Fawb Kev Tshawb Fawb: Los Ntawm Phau Ntawv Folding rau Hmoov Metallurgy
Cov txheej txheem tsoosing tsoosing ntawm kev paub ntawm cov kws ntaus hlau, thiab ntau dua cov khaub ncaws tuaj yeem ua rau muaj kev cuam tshuam hauv interlayer sib zog (feem ntau tswj hwm ntawm 86-512 txheej). Kev siv thev naus lausOGS nyuam qhuav ua rau muaj cov hmoov ua Damascusous ua rau muaj kev kub ntxhov hauv lub tshuab raj loj. Nws hardness tuaj yeem ncav cuag HRC 62, thaum nws khoov tau muaj zog tau nce 30%, thiab cov qauv raug mus txog ntawm 0.01 hli, deb tshaj li phau ntawv Forging.
2, Hardness Kev Ua Tau Zoo: Los ntawm kev kuaj cov ntaub ntawv los ua pov thawj pov thawj
Quantitative Qhov ntsuas: Tshaj dhau txoj kev ua haujlwm ntawm cov pa hlau
Lub hardness ntawm laminated Damascus hlau feem ntau yog ntawm HRC 58-62, nyob ntawm cov khoom ntawm cov txheej txheem tseem ceeb. Piv txwv li:
VG-10 Cov tub ntxhais Laminated Steel: HRC 60-61, nrog sharmance retention ob zaug uas ntawm dog dig 440c hlau;
Ruifen Damascus Hlau: HRC 62, txiav yuam txog 8.5n (storly stainless hlau yog li ntawm 6n);
Ancient UZI steel: lub hardness ntxiv yog hrc 58-60, tab sis cov pa roj carbon monoxent, tab sis cov pa roj carbon monoxent ua rau nws muaj qhov tseeb dua li niaj hnub cov tawv tawv.
Cov Ntaub Ntawv Siv: Kev ua tau zoo rau hauv daim teb ntawm cov riam ua noj
Hauv cov riam ua mov kuaj, laminated Damascus Steel tsom cov txiaj ntsig tseem ceeb:
Hnav Kuj: Tom qab txiav cov duab qhia 1000 zaug, qhov tseeb ntawm cov hniav txo qis los ntawm tsuas yog 15% (dog dig hlau tau los ntawm ntau dua 50%);
Corrosion Kuj: 316L stainless hlau txheej yog hloov cov roj carbon hlau muaj zog, txuas ntxiv ntawm cov ntsev kom ntev mus txog 72 teev (steel hlau tsuas yog 24 teev);
Lub cev tswj hwm: tus cim micro serrated qauv cia li pom cov carbide tshiab bands tom qab hnav, ua tiav "tus kheej cellening" nyhuv.
3, Kev Ntsuam Xyuas Ntev: Cov khoom siv philosophy tshaj lub sijhawm
Anti Rog Rog Tsim: Interlayer Kev Nyuaj Siab Rho Tawm Mechaism
Cov qauv laminated lamin tau zoo sib cav sib ceg los ntawm interlayer cuam tshuam. Thaum cov hniav yog cuam tshuam, cov nrib yuav tsum dhau los ntawm ntau cov interfaces nrog ntau tawv tawv, siv lub zog thiab kev hloov pauv txhua zaus nws kis tau. Piv txwv li, hauv simulated pob txha txiav ntsuas ntawm Japanese "Laminated Riam, tsis muaj riam siv hluav taws xob tom qab 50000 kev cuam tshuam.
Ib puag ncig kev hloov kho: kev ua tau ruaj khov los ntawm huab txias kom kub
Niaj hnub nimno laminated steel txhim kho kev tiv thaiv ib puag ncig los ntawm kev ua kom ua tau zoo:
Low temperature toughness: Adding nickel (Ni) element to maintain an impact toughness value of>30J / cm ² ntawm -40 degree;
Kev kub siab: ntxiv rau ntawm Molybdenum (MO) thiab Vanadium (V) muaj peev xwm tswj cov hardness (muaj peev xwm los tswj cov hardness (muaj peev xwm los tswj lub hardness (muaj peev xwm los tswj kev nyuaj) txog qib 400℃ntawm 400℃ntawm cov hlau dog dig.
Tus nqi kav: kev siv hluav taws xob ntawm ntev -} kev siv
Txawm hais tias thawj tus nqi ntawm laminated Damascus Steel yog 3-5 zaug uas ntawm cov hlau zoo tib yam, nws tus nqi kav tag yog qis dua:
Sib tsoo ntau: Kev tshaj tawm cov kws ua txuj ntsuas kev ntsuam xyuas qhia tau tias cov riam ua mov laminated ua txhua 6, thaum cov hlau ua tib zoo li txhua lub hli;
Kev Pab Lub Neej: Hauv chav ua noj ua lag luam uas tau siv rau 8 teev hauv ib hnub, lub neej ntawm tus laminated riam tuaj yeem ncav ntau dua 10 xyoo (dog dig steel riam tsuas yog siv 2-3 xyoos nkaus xwb);
Reallual Tus Nqi: Qhov thib ob {- Tes Ua Kev Ua Lag Luam Tus Nqi Laminated Tus Nqi Laminated Hwj Siab-}}}}}}}}}} {prot} tsim tawm rab riam.
4, Kev Lag Luam Trend: Kev Sib Tham Txog Kev Lag Luam thiab Cov Khoom Siv
Ntsortonic Forging: AI Pab Txheej Txheej Txhim Kho Kom Txhim Kho
Lub lag luam hauv Solingen, Lub teb chaws Yelemees tau qhia txog Ai Algorithms kom rov xam cov khaubncaws sab nraud ntawm cov khaubncaws sab nraud ntawm cov cuab yeej siv. Piv txwv li, tua cov kab tua hniav rau 43 txheej txheej txheem (ntsuas qhov tsis zoo), thaum lub khob hliav tshuaj siv 127 txheej (txhim kho pom kev ua tau zoo).
Nano txheej: dual txhim kho ntawm hardness thiab lubrication
Deposter - Zoo li cov pa roj carbon (DLC) txheej ntxiv rau HRC 70, thaum txo cov hlau sib txhuam tau ntxiv rau 0.05 (0.3 rau kev sib txawv ntawm cov hlau), 0.3 ntxiv txo kev txiav tawm.
Kev tsim khoom siv khoom: Kev thov cov khoom siv ua rov ua dua tshiab
Qee cov tuam ntxhab tau pib siv cov hlau rov ua rau cov laminated forging. Piv txwv li, "eco Damascus" series tau tsim los ntawm hniav HQ hauv Tebchaws Meskas nrog kev phais lub caij nplooj ntoo hlav hluav taws xob hlau kom txo cov pa roj carbon monissions thaum tswj kev ua tau zoo.
