Tsawg Coefficient ntawm Thermal Expansion (Core Advantage)
Lub ntsiab kom zoo dua ntawm INVAR yog nyob rau hauv nws tsis tshua muaj coefficient ntawm thermal expansion. Nyob rau hauv qhov kub ntawm -100℃mus rau +200 degree, nws qhov nruab nrab linear expansion coefficient yog tsawg li 1.2 × 10⁻⁶ /℃rau 1.8 × 10⁻⁶ / degree, ho qis dua li cov carbon hlau zoo tib yam (kwv yees li 11 × 10⁻⁶ thiab 1℃stainless hlau) 10⁻⁶ / degree). Nyob rau hauv chav tsev kub mus rau 100℃ncua sij hawm, nws expansion coefficient yuav tsawg li 0.8 × 10⁻⁶ /℃rau 1.2 × 10⁻⁶ / degree, thiab txawm mus zero expansion nyob rau hauv tej yam kub thiab txias. Cov cuab yeej no ua rau nws tsis tuaj yeem hloov pauv hauv cov ntawv thov nrog cov kev xav tau siab heev rau qhov ntev thermal stability, xws li precision ntsuas ntsuas, laser resonators, thiab satellite structural Cheebtsam.
Zoo plasticity thiab kev ua haujlwm zoo
INVAR nthuav tawm cov yas zoo thiab ua haujlwm tau zoo nyob rau hauv lub xeev annealed, nrog rau elongation txog li 30% mus rau 40% thiab txo qhov siab ntawm cheeb tsam. Nws tuaj yeem dhau los ua ntau yam txheej txheem txias txias xws li txias dov, kos duab txias, stamping, thiab dabtsi yog khoov, thiab tseem tuaj yeem tsim ua ntau hom ntawv xws li daim hlau, strips, xov hlau, thiab cov raj los ntawm cov pa machining txoj kev xws li tig, milling, thiab drilling. Nws muaj lub siab nyiam ua haujlwm nyuaj, yog li nws raug pom zoo kom siv cov cuab yeej ntse thiab cov kev txiav tsim nyog.
Zoo heev low -kub txhua yam khoom
INVAR tsis ua rau lub cev tsis muaj zog - mus rau - kev hloov pauv hauv qhov qis - qhov kub thiab txias thiab tuav lub zog zoo thiab tawv txawm nyob ntawm -196℃(kua nitrogen kub), yam tsis muaj qhov kub tsawg - qhov kub thiab txias tawg. Cov cuab yeej no ua rau nws yog cov khoom siv tseem ceeb rau cov roj liquefied natural gas (LNG) nqa thiab cov tso tsheb hlau luam-vim LNG khaws cia ntawm kwv yees li -162 degree, qhov twg cov hlau zoo tib yam yuav muaj qhov txias txias. INVAR qhov qis coefficient ntawm thermal nthuav dav txo qhov kev ntxhov siab ntawm qhov txias txias, ua kom muaj kev ruaj ntseg ntawm cov tso tsheb hlau luam.
Zoo dimensional stability thiab lub koom haum stability
INVAR tuaj yeem ua tiav austenitic microstructure ruaj khov thiab ruaj khov zoo ntawm cov txheej txheem kho cua sov (annealing + stabilization). Thaum lub sij hawm ntev - kev pab cuam, nws qhov kev hloov pauv me me, ua rau nws haum rau cov cuab yeej precision thiab cov qauv ntsuas ntsuas uas yuav tsum tau ua kom ntev ntev - kev cia siab rau lub sijhawm thiab qhov ruaj khov. Kev kho kom ruaj khov (tuav ntawm 300-400℃rau 10-20 teev) zoo tshem tawm cov kev ntxhov siab uas seem, txo qis qhov dav ntawm kev siv tom ntej.
Kev ua haujlwm vuam zoo
INVAR tuaj yeem koom nrog siv txoj hauv kev xws li TIG welding, tsis kam vuam, thiab electron beam vuam. Thaum vuam, nws raug nquahu kom siv cov xaim xaim ntawm tib INVAR cov ntaub ntawv los xyuas kom meej tias qhov tsis tshua muaj kev nthuav dav ntawm cov vuam seam zoo ib yam nrog cov khoom siv hauv paus. Kev ntxhov siab- feem ntau yuav tsum tau ua kom muaj kev ntxhov siab tom qab vuam kom tshem tawm cov qoob loo loj hlob lossis cov txheej txheem precipitated uas yuav tshwm sim hauv tshav kub- qhov cuam tshuam, yog li tiv thaiv kev hloov pauv hauv zos coefficient ntawm thermal expansion.

Ntev -Lub sij hawm Thermal thiab Dimensional Stability:
INVAR nthuav tawm qhov zoo microstructural stability thiab qhov me me hloov pauv thaum nyob rau hauv kev pab cuam ntawm qhov kub thiab txias tsawg dua los yog sib npaug rau 200℃rau ncua sij hawm. Txawm li cas los xij, kev hloov pauv me me (hnub nyoog shrinkage) yuav tshwm sim thaum lub sij hawm ntev - cia ntawm chav tsev kub. Nws raug nquahu kom ua kev kho kom ruaj khov (tuav ntawm 300-400℃rau 10-20 teev) ntawm cov khoom siv high-precision kom tshem tawm cov kev ntxhov siab seem, ua kom cov qauv austenitic ruaj khov, thiab txo qis qis thaum siv tom ntej. Qhov tseem ceeb, INVAR yog qhov nkag siab zoo rau cov cua txias thaum kho cua sov. Cov cua txias nrawm tuaj yeem ua rau austenite supersaturation, ua rau nag lossis daus theem hloov thaum siv tom qab thiab ua rau muaj kev hloov pauv hauv coefficient ntawm thermal expansion.
Kev kho cua sov
Kev kho cua sov ntawm INVAR muaj kev txiav txim siab ntawm qhov kawg microstructural stability thiab qhov tseeb qhov tseeb, nrog rau cov lus qhia raws li hauv qab no:
1. Annealing (kom daws tau qhov kev ntxhov siab ntawm machining thiab stabilize microstructure): Thaum tshav kub kub mus rau 815-830℃(1525℃F), tuav rau 0.5 teev ib nti ntawm thickness, rauv txias ntawm tus nqi tsawg dua los yog sib npaug rau 200℃F ib teev, thiab cua txias tom qab txias hauv qab 600℃F.
2. Kev kho kom ruaj khov (pom zoo rau siab-Qhov Precision): Tuav ntawm 300-400℃rau 10-20 xuab moos, tom qab ntawd maj mam txias rau hauv chav sov kom tshem tawm cov kev ntxhov siab uas seem, ua kom lub austenitic microstructure ruaj khov, thiab txo qis qhov dav dav.
3. Kev kho kev ntxhov siab (Tom qab Machining): Tuav ntawm 200-300℃rau 1-2 teev, ces cua txias kom tsis txhob deformation los ntawm kev txiav kev ntxhov siab.
Faj seeb: INVAR yog rhiab heev rau cov cua txias thaum kho cua sov. Txhua qhov kev kho cua sov yuav tsum tau ua los ntawm kev ua kom txias txias; Kev ua kom txias sai sai (xws li dej quenching) tuaj yeem ua rau tsis ruaj khov microstructure thiab kev hloov pauv tom ntej.
