Cov txheej txheem ntawm kev ua ib lub home rab riam?

, Cov khoom xaiv: prelude mus rau lub suab nkauj ntawm cov hlau
Cov tub ntxhais tseem ceeb ntawm Damascus riam nyob rau hauv nws cov composite steel qauv, thiab niaj hnub rab riam siv feem ntau siv 3-5 sib txawv cov ntsiab lus rau laminated. Coj tus yam ntxwv ntawm tus kws ua ntoo ua ke "sib xyaw ua ke", nws cov hniav muaj cov ntsiab lus carbon (nrog rau 3.5% npib hlau (nrog 52100 chromium). Qhov kev sib xyaw ua ke no tsis tsuas yog ua kom qhov tseeb ntawm cov hniav, tab sis kuj tseem ua cov qauv sib piv siab los ntawm cov kua tsib ntawm cov kua qaub.
Cov ntaub ntawv sib piv ua raws li txoj ntsiab cai ntawm "sib txuas ua ke thiab hloov hluav taws xob thiab yoog raws": tawv steel muab txiav kev ua tau zoo, thaum mos steel txhim kho kev cuam tshuam. Raws li cov ntaub ntawv los ntawm Swedish Steel Kuaj, tom qab 300 txheej ntawm folding forging, thaum lub zog ntau dua li ntawm ib qho hlau, thaum lub hardness nyob rau hauv cov golden ntau ntawm hrc58-60. Riam ua kemer brian muag khoom lag luam preved 1080 carbon carbon steel, thiab 151 lub caij nplooj ntoo hlau nyob rau hauv ib tug ua persian tsov rog, tsim qauv gradient zoo ib yam li cov duab kos duab.
2, Forging txheej txheem: molecular recombination uas tau ua kom zoo dua los ntawm kev suav tsis txheeb thiab kev txom nyem
1. Cov kos duab ntawm kev tswj hluav taws
Cov txheej txheem FORT
Tsaus liab (800 degree): Cov hlau yog nyob rau hauv thaum ntxov ntxov ntawm autustenitization thiab tsis muaj plasticity
Cherry liab xim (950 degree): kev pom kev zoo saib xyuas qhov kub, carbon caij carbon pib ua rau tsis sib xws
Ci daj (1100 degree): nce qhov tseem ceeb ntawm kev hlawv, nws yuav tsum tau muab tshem tawm tam sim ntawd thiab forged
Tus kws qhia khoom siv tes ua rau "peb {- preheat los kho hluav taws kub ua ntej, thiab thaum kawg siv hluav taws kub kom ncav cuag 1250℃rau kev tseem ceeb. Cov txheej txheem no tuaj yeem kho cov mov loj ntawm cov hlau rau Astm qib 8, hloov kho nruj heev.
2. Kev zoo nkauj ntawm kev muab quav folding fquam kev ua lej
Txhua lub txee yuav ua rau muaj kev nthuav dav ntxiv nyob rau hauv tus naj npawb ntawm cov khaubncaws sab nraud povtseg, thiab cov txheej txheem forging raug yog raws li hauv qab no:
Thaum pib cov khaubncaws sab nraud povtseg: 1 txheej txhua rau 3 hom hlau, nrog tag nrho ntawm 3 txheej
Thawj zaug folding: tom qab forging, tus naj npawb ntawm cov khaubncaws kom txog 6
Thib ob quav: nce tus naj npawb ntawm cov khaubncaws sab nraud rau 12
Thib peb cov ntawv ntim: tsim 24 Txheej Txheem Txheej Txheem Yooj Yim
Twisted Forging: Los ntawm Twisting ntawm 45℃kaum, tus kauv qauv yog tsim tawm hauv txheej
Tom qab 12 folds, cov hniav tuaj yeem ua tiav microstructure ntawm 4096 txheej. Japanese Moidurgists tau nrhiav pom los ntawm Electron microscopy uas tiv thaiv cov qauv txheej txheem cig, tso cai rau cov cuab yeej los tswj hwm kev ncaj ncees ntawm 200kg.
3. Lub cev siv lub cev ntawm cov qauv tsim
Lub ntsiab lus ntawm cov qauv Damascus yog qhov sib txawv hauv kev xeb tus nqi ntawm cov hlau nrog cov khoom sib txawv ntawm cov roj carbon ntau. Thaum lub sij hawm pickling:
Dark grooves are formed in the high carbon steel area (carbon content>1.0%)
Tsawg Cov Khoom Siv Hluav Taws Xob (Cov Ntsiab Lus Carbon<0.5%) maintains light colored protrusions
Gloss kab txaij yog tsim nyob rau hauv lub npib tsibel thaj chaw vim corrosion tsis kam
Tus kws qhia khoom siv tau txais cov tshuaj txhuam tsev, ua ntej, ua ntej, ci ntsa iab rau ntawm "
3, Kev Kho Cua sov: Phoenix Nirvana ntawm Hlau
1. Kev tswj hwm ntawm kev txiav txim siab quenching
Kev xaiv ntawm quenching nruab nrab ncaj qha cuam tshuam cov kev ua tau zoo ntawm cov cuab yeej txiav:
Cov roj quenching: ntxhia roj cua txias ceev ntawm 800℃/ s, haum rau kev ua kom muaj hardness blades
Dej Quenching: tus nqi txias nce mus txog 1500℃/ s, uas tuaj yeem ua rau yooj yim tawg thiab xav tau kev siv cov av nkos buffering
Graded quenching: ua ntej kom sov nyob rau hauv 550℃ntsev da dej, tom qab ntawd hloov mus rau cov roj rau cua txias, uas tuaj yeem txo qhov tsis zoo
Tus kws ua haujlwm ua haujlwm "Huibi" admts ib hom kua txiv neej ua kua: Ua ntej ua kom sov rau hauv 1200 degree, thiab tom qab ntawd hloov mus rau cov dej khov kom tiav rau cov martensitic kev hloov pauv. Cov txheej txheem no tau ua rau lub ntsej muag tawv tawv ntawm HRC60, thaum rov qab ntawm cov hniav tau tuav cov tawv ntawm HRC45.
2. Kev ntxhov siab ntawm cov txheej txheem tempering
Cov txheej txheem tempering yuav tsum tau kho kom meej txog kev tswj qhov kub thiab txias:
Tsawg Tsawg Kub Kub (150-250 Degree): Tshem tawm quenching kev ntxhov siab thiab txhim kho kev nyuaj
Nruab nrab kub kub (300-450 degree): tiav qib siab zoo tshaj plaws, haum rau kev ua cov khoom caij nplooj ntoos hlav
Kub kub tempering (500-650 degree): hloov kho yooj yim heev, siv rau kev zam txim loj
Damascus feem ntau siv peb lub sijhawm tempering:
Thawj Zempering: Khaws ntawm 200℃rau 2 teev rau tshem tawm kev ntxhov siab saum npoo
Qhov thib ob tempering: khaws ntawm 250℃rau 1.5 teev, kho cov qauv tseem ceeb
Peb npau taws thib peb: tuav ntawm 180℃rau 3 teev kom ruaj khov ntawm cov qauv siv lead ua
4, precision Ua: sublimation los ntawm riam phom mus rau artworks
1. Millimeter Nyob saib txoj kev sib tsoo tshuab
Lub Damascus saum toj kawg nkaus yuav tsum muaj 12 txoj kev sib tsoo cov txheej txheem:
Kev sib tsoo ntxhib rau theem: Siv 80 tus ncej sib tsoo kom tshem tawm cov cim forging
Nruab Nrab Sib Tsoo Theem: 400 Mesh Sandpaper Yas Txiav Ntug Contour
Cov theem zoo sib tsoo: 3000 grit sib tsoo pob zeb los tsim daim iav ua haujlwm
Polishing theem: nano nplai alumina polished txog 10000 mesh
Raws li cov ntaub ntawv los ntawm Nyij Pooj me me Hiroji Yamada, ib qho hniav polished nrog 10000 GRIT muaj qhov cuab yeej thiab khoom noj khoom noj khoom noj 82% qis dua.
2. Ergonomic tsim ntawm riam kov ntau lawm
Tus kov tsim yuav tsum ua tau raws li "peb tus ntiv tes nyem txoj kev":
Tsov lub qhov ncauj qhov ncauj: kub loj nrog txoj kab uas hla ntawm 32-3MM
Tus ntiv tes ntawm qhov chaw uas muag khoom tob: Kev tswj hwm ntawm 8-10 hli
Nruab nrab ntawm txoj haujlwm nqus haujlwm: qhov zoo tshaj plaws tshuav taw tes 4-6cm deb ntawm tes xuas tes
Tus kws ua liaj ua teb Rhiav's "kev sib raug zoo" siv "cov qauv xuab zeb" kov:
Cov txheej txheem: G10 aviation composite muab lub zog
Nruab Nrab Txheej: Liab Rosewood muab kov sov
Nto: Tiaj nrog tooj dag rivets los txhim kho cov kev thov kho kom zoo nkauj
5, Kev tawg thiab nrhav kev tshiab hauv cov khoom siv tes ua niaj hnub
1. Daim ntawv thov ntawm hmoov metallurgy thev naus laus zis
Lub RWL34 hmoov hlau tsim los ntawm Deatasin lub tuam txhab hauv Sweden ua cov hmoov hlau ua kom loj me me ntawm<50 μ m through gas atomization method. After hot isostatic pressing, its performance surpasses traditional forged steel:
Lub zog tensile: 2200Mpa (cov hlau tsoos 1800mpa)
Kev Cuam Tshuam Cov: 45J (Tsoos Hlau 30J)
Corrosion Kuj: tsis muaj xeb tom qab 96 teev ntawm cov tshuaj ntsev
2. Kev sib xyaw ntawm 3D luam ntawv tshuab
Hniav HQ hauv Tebchaws Meskas tau ua tiav 3D luam tawm ntawm Damaxes Hlau:
Siv Laser Laser Melting (SLM) Tshuab Rau Melt Steel Hmoov Txheej Los Txheej
Kev paub cov ntsiab lus carient elient faib los ntawm kev tswj laser fais fab
Luam ntawv raug nce mus txog 0.02mm, muaj peev xwm ntawm kev sau ncaj qha ua qauv
Txawm hais tias cov thev naus laus zis no tuaj yeem tswj tau qhov qauv zoo, nws tseem tsis tuaj yeem hloov qhov zoo kom forgal forging hauv cov khoom tawv.
