1. Core Mechanical Property Indicators (Room Temperature, After Standard Heat Treatment)
Kev daws annealing: Kub rau 927–982 degree, tuav rau 30–60 feeb, ces dej-quench mus rau chav tsev kub.
Kev laus kev kho mob: Rov ua kom sov rau 482-510 degree, tuav rau 4-8 teev, ces cua- txias.
Yield zog (0.2% Offset): Ntau dua los yog sib npaug793 MPa (115,000 psi)
Tus nqi no sawv cev rau qhov kev ntxhov siab uas cov hlau tau dhau mus tas li cov yas deformation ntawm 0.2%. Nws yog ib qho tseem ceeb rau kev ntsuam xyuas cov hlau tsis kam rau deformation nyob rau hauv load, uas yog siab tshaj qhov uas tsis yog - tshav kub- kho Monel 400 (yield zog tsuas yog 240 MPa, 35,000 psi).
Elongation (hauv 50 hli ntsuas qhov ntev): Ntau dua los yog sib npaug20%
Elongation qhia txog cov yas deformation muaj peev xwm ntawm cov hlau ua ntej tawg. Monel K500 tuav zoo ductility thaum muaj ultra-lub zog siab, uas tsis txhob nkig tawg thaum ua haujlwm (xws li, txias taub hau, threading) lossis kev pabcuam.
2. Qhov cuam tshuam ntawm kev kho cua sov hloov pauv ntawm cov ntsuas
Kev laus tsis tiav (qhov kub thiab txias lossis lub sijhawm luv luv): Cov nag lossis daus ntawm Ni₃(Al, Ti) cov theem ntxiv tsis txaus. Lub sijhawm no, lub zog tawm los txo qis rau 620-700 MPa, thaum lub elongation nce mus rau 25-30%.
Tshaj - laus (kub kub lossis ntev): Cov theem ua kom muaj zog coarsen thiab sib sau ua ke, ua rau txo qis zog ntawm 690-760 MPa, thiab elongation me ntsis nce mus rau 22-26%.
Tshem tawm kev laus (tsuas yog tshuaj annealing): Lub alloy yog nyob rau hauv ib tug softened xeev, nrog ib tug yield zog ntawm tsuas yog hais txog 276 MPa thiab ib tug elongation txog li 40%, uas poob lub tseem ceeb kom zoo dua ntawm siab zog.
3. Cov nyhuv ntawm qhov kub thiab txias ntawm cov khoom muaj zog thiab elongation
Yield zog trend: Raws li qhov kub thiab txias, lub zog ntawm Monel K500 maj mam txo. Thaum qhov kub siab tshaj 427 degree, qhov txo qis nrawm, vim tias cov theem ntxiv zog pib yaj thiab poob lawv cov kev sib zog ua kom muaj zog.
Elongation trend: Nrog rau qhov kub thiab txias, qhov ductility ntawm cov hlau txhim kho, thiab qhov elongation nce raws li, uas txhais tau hais tias cov hlau tsis tshua muaj nkig tawg nyob rau hauv siab - qhov kub thiab txias.
4. Cov Lus Cim Tseem Ceeb
Qauv Qauv: Rau forged lossis txias- ua haujlwm Monel K500 fasteners, lub zog tawm los yuav yog 5-10% siab dua tus nqi tus qauv, thaum lub elongation yuav txo los ntawm 2-3% vim ua hauj lwm hardening.
Txuj kev ua raws cai: Cov ntawv thov sib txawv muaj cov kev cai sib txawv rau cov ntsuas. Piv txwv li, aerospace-qib Monel K500 yuav tsum muaj lub zog tawm los ntawm Ntau dua lossis sib npaug rau 827 MPa, thaum cov khoom lag luam- qib yuav qis dua me ntsis.
