Molybdenum Aluminium Alloy

 

Molybdenum Aluminium Alloy yog cov khoom siv siab tshaj -cov khoom siv alloy ua los ntawm kev siv txhuas los ua lub hauv paus thiab ntxiv cov hlau molybdenum (cov ntsiab lus molybdenum feem ntau yog nruab nrab ntawm 2% thiab 30%, thiab tuaj yeem ncav cuag 50% mus rau 85% thaum siv los ua cov hlau nruab nrab). Cov hlau no yog tsim los rau hauv cov kev daws teeb meem los yog cov sib txuas sib txuas los ntawm cov txheej txheem melting lossis hmoov metallurgy, kev sib koom ua ke ntawm cov yam ntxwv tsis tshua muaj siab ntawm txhuas nrog lub siab melting point thiab siab hardness zoo ntawm molybdenum. Nws yog ib qho kev daws teeb meem zoo tshaj plaws rau cov teeb meem ntawm lub zog tsis txaus thiab cov cua sov tsis zoo ntawm cov ntshiab txhuas, thiab tau siv dav hauv high-kawg kev lag luam xws li aerospace, automotive manufacturing, thiab hluav taws xob thiab hluav taws xob kev lag luam.

 

 

1.Hloov siab zog thiab hardness

Cov txhuas-molybdenum alloy yog ntxiv dag zog los ntawm cov khoom sib tov ntawm molybdenum atoms thiab tsim ntawm intermetallic compounds (xws li Al₁₂Mo, Al₈Mo₃), ua kom muaj zog tensile thiab hardness. Nws lub zog muaj zog tshaj qhov zoo tib yam aluminium alloys, thiab nws tseem muaj peev xwm tuav tau zoo heev creep kuj nyob rau hauv siab - qhov kub thiab txias ib puag ncig, zoo tiv thaiv deformation txaus ntshai thaum lub sij hawm ntev - siv, thiab yog haum rau siab - load structural Cheebtsam.

 

2. Qhov zoo tshaj plaws tshav kub tsis kam thiab tsis kam mus rau siab -kub creep

Ordinary aluminium alloys muaj kev poob qis hauv lub zog siab tshaj 200 degree, thaum lub sij hawm recrystallization kub ntawm aluminium-molybdenum alloys tau nce ntau vim qhov sib ntxiv ntawm molybdenum. Lawv tuaj yeem tuav lub zog siab thiab oxidation tsis kam ntawm qhov kub thiab txias li 300℃lossis siab dua. Cov yam ntxwv no ua rau lawv cov khoom siv tseem ceeb rau cov khoom siv cav, siab - cov khoom siv kub, thiab lwm yam kev siv.

 

3. Zoo heev corrosion kuj

Cov khoom molybdenum txhim khu kev ruaj ntseg ntawm oxide zaj duab xis ntawm aluminium nto thiab txhim kho qhov tsis kam rau pitting corrosion hauv chloride ion ib puag ncig. Aluminium-molybdenum alloys ua tau zoo tshwj xeeb hauv marine engineering, cov khoom siv tshuaj lom neeg thiab lwm qhov chaw ntub dej lossis corrosive, ua kom lub neej ntev ntawm cov khoom siv.

 

4. Kev ua haujlwm zoo heev thiab lub cev muaj zog

Los ntawm cov khoom tsim kho kom zoo, aluminium-molybdenum alloy tuav lub zog siab thaum tseem muaj cov yas zoo thiab ua haujlwm tau zoo, ua kom casting, forging, thiab mechanical processing. Nws tau txais lub thermal thiab hluav taws xob conductivity ntawm txhuas thiab yog tsim rau kev siv xws li tshav kub dissipation substrates thiab conductive structural Cheebtsam.

 

 

 

1. As an intermediate alloy (with high molybdenum content, >50%)

(1) Aerospace thiab 3D luam ntawv: High-purity aluminium-molybdenum alloys (xws li AlMo60, AlMo80) yog cov tseem ceeb nruab nrab alloys rau titanium alloy manufacturing, siv nyob rau hauv dav hlau cav hniav, fuselage Cheebtsam, thiab kev npaj ntawm 3D- luam ntawv hlau hmoov khoom.

(2) Grain refiner: Ntxiv ib qho me me ntawm txhuas-molybdenum alloy thaum lub sij hawm txhuas alloy casting tuaj yeem kho cov qauv ntawm cov nplej, tshem tawm cov kab nrib pleb thiab cov kab nrib pleb, thiab txhim kho cov khoom siv dag zog thiab cov txiaj ntsig ntawm cov castings, thiab tau dav siv nyob rau hauv siab - kawg aluminium alloy ntau lawm.

 

2. Raws li siab -kev ua tau zoo aluminium alloy (molybdenum ntsiab lus 2% - 30%)

(1) Aerospace thiab kev tiv thaiv: Siv rau kev tsim khoom siab - qhov kub thiab txias ntawm cov dav hlau, cov foob pob hluav taws xob, foob pob hluav taws cov qauv thiab cov tshuab compressor ntawm lub dav hlau. Nws lub zog siab thiab kub tsis kam ua kom muaj kev sib npaug ntawm lub teeb yuag thiab kev ntseeg tau.

(2) Automotive kev lag luam: Siv rau lub cav pistons, lub tog raj kheej taub hau, turbocharger rotors thiab lwm yam khoom, ua kom cov roj efficiency thiab lub zog tso zis los ntawm siab - kub lub zog thiab lub teeb yuag yam ntxwv.

(3) Electronics thiab hluav taws xob: Raws li lub tshav kub dissipation substrate rau siab -power LEDs, ib daim ntawv tshav kub dissipation rau integrated circuits thiab lead thav duab cov ntaub ntawv, leveraging nws high thermal conductivity los daws cov teeb meem kub dissipation.

(4) Chemical thiab marine engineering: Tsim los rau corrosion-cov valves, lub cev twj tso kua mis, cov khoom siv hluav taws xob thiab cov khoom siv nkoj, ua tau raws li qhov yuav tsum tau ua rau lub sijhawm ntev - ua haujlwm nyob rau hauv ib puag ncig hnyav.
