Khoom Taw Qhia

1. Tshuaj ntsuam xyuas muaj pes tsawg leeg

Cov tshuaj tseem ceeb ntawm 2.4619 (NiCr22Mo7Cu) thiab 2.4618 (NiCr22Mo6Cu) muaj xws li carbon (C), silicon (Si), manganese (Mn), chromium (Cr), molybdenum (Mo), nickel (Ni), niobium (Nb), cobalt (Co) thiab hlau (Fe). Ntawm lawv, npib tsib xee yog lub ntsiab matrix ntawm ob lub alloys, muab lawv zoo toughness thiab corrosion kuj. Qhov sib ntxiv ntawm chromium, molybdenum thiab niobium ntxiv txhim kho cov hlau tsis kam rau oxidation thiab corrosion, tshwj xeeb tshaj yog nyob rau hauv high-temperature ib puag ncig.

Tshwj xeeb, cov ntsiab lus carbon hauv 2.4619 qis dua (tsawg dua lossis sib npaug rau 0.015%), uas yuav pab txo qhov brittleness ntawm alloy. Nyob rau tib lub sijhawm, nws cov ntsiab lus molybdenum yog dav (6.0~ 8.0%), uas pab txhim kho corrosion kuj ntawm cov alloy. Cov ntsiab lus niobium hauv 2.4618 yog qhov siab (1.75 ~ 2.5%), uas txhim kho qhov kub thiab txias stability thiab oxidation tsis kam ntawm cov hlau.

2. Cov yam ntxwv ua tau zoo

1. Corrosion tsis kam: Vim muaj chromium siab, siab molybdenum thiab qhov sib ntxiv ntawm qhov tsim nyog ntawm niobium, ob lub alloys qhia zoo corrosion kuj nyob rau hauv ntau yam xov xwm, tshwj xeeb tshaj yog nyob rau hauv oxidizing media.
2. Kev ruaj ntseg kub siab: Cov ntsiab lus niobium siab hauv 2.4618 muab kev ruaj ntseg zoo dua ntawm qhov kub thiab txias thiab tsim nyog rau qhov kub thiab txias ua haujlwm.
3. Mechanical zog: Ob lub alloys no muaj lub zog siab thiab hardness thaum tuav zoo toughness thiab ductility, muab lawv zoo heev mechanical zog nyob rau hauv ntau yam kev siv.

3. Daim ntawv thov teb

1. Aerospace: Vim lub siab kub stability thiab corrosion kuj ntawm nickel-raws li alloys, lawv tau dav siv nyob rau hauv lub aerospace teb, xws li cav qhov chaw, combustion chambers, turbine hniav, thiab lwm yam.
2. Petrochemical kev lag luam: Ob lub alloys no feem ntau siv rau hauv kev lag luam petrochemical los tsim cov kav dej corrosion-resistant, li qub, twj tso kua mis, kub exchangers thiab lwm yam khoom siv.
3. Nuclear zog: Cov hluav taws xob tsis zoo ntawm cov nickel-based alloys muab qee qhov kev cia siab rau lawv hauv thaj chaw ntawm lub zog nuclear, xws li cov khoom siv hluav taws xob thiab cov twj tso kua mis hauv nuclear reactors.
