Monel K500 Monel alloy khoom thiab cov txheej txheem qhia
Monel K500 cov ntaub ntawv qhia
Monel K500 alloy yog Ni-Cu-raws li alloy. Los ntawm kev ntxiv me me ntawm Al thiab Ti cov ntsiab lus, Ni3 (Al, Ti) theem yog precipitated. Nws khaws cov kev tiv thaiv zoo heev ntawm Monel 400 alloy thiab tib lub sijhawm muaj lub zog siab vim los nag lossis daus. , yog dav siv hauv roj av, tshuaj lom neeg kev lag luam, atomic zog thiab lwm yam kev lag luam.
Los ntawm kev ntxiv Al, Ti thiab lwm cov ntsiab lus rau Ni-Cu matrix, cov nag lossis daus hardening Monel K500 alloy yog tsim. Cov alloy no qhia tau hais tias zoo heev corrosion kuj nyob rau hauv seawater, acid, alkali thiab ntsev ib puag ncig, thiab yog sib xws nrog Ni-Cr-raws li alloys thiab nag lossis daus-hardened low-alloy steels muaj chav kub lub zog thiab hardness piv rau Ni-Cr-raws li alloys. . Lawv yog cov tawv thiab yas txawm tias qhov kub thiab txias ntawm -25K thiab tuaj yeem tswj tau lawv lub zog ntawm qhov kub txog li 920K. Cov alloys tshwj xeeb tshaj yog tsim rau kev ua teb roj tsim hluav taws xob. Lub twj tso kua mis ntawm lub twj tso kua mis submersible.
Cov nyhuv ntawm cov kab txuas ntxiv rau qhov kub siab plasticity ntawm Monel K500
(1) Ntxiv cov lej ntawm Mg rau Monel K-500 alloy tuaj yeem ua rau cov qoob loo ciam teb sib txuas ua ke thiab txhim kho cov khoom kub kub.
(2) Qhov kub-kub plasticity ntawm kev sim alloy nrog cov lej ntawm Mg, Cr thiab Co ntxiv nyob rau tib lub sijhawm tau txhim kho zoo, thiab nws nthuav tawm qee qib ntawm superplasticity. Tus nqi rhiab heev index m ntawm 1010 degree yog 0.32, thiab qhov siab tshaj plaws elongation yog 240%.
(3) Kev suav theoretical ntawm kev ua haujlwm tawg ntawm impurity ntsiab cais ntawm cov ciam teb pom tau hais tias Mg, Cr thiab Co muaj cov txiaj ntsig ntawm kev txhim kho cov qoob loo ciam teb ntawm Ni-Cu alloy, thiab yog li ntawd tuaj yeem txhim kho lub siab kub ntawm plasticity. Monel K-500 alloy.
(4) Lub zog deformation ua kom muaj zog tsawg thaum lub sij hawm superplastic deformation, thiab cov txheej txheem yuav raug tswj los ntawm diffusion.
Monel K500 kev laus tiv thaiv kev tawg
(1) Tom qab loj deformation, MonelK-500 alloy muaj ib tug muaj zog nyiam rau hnub nyoog tawg. Cov kab nrib pleb pib rau ntawm qhov chaw thiab nthuav tawm mus rau qhov chaw, nrog rau cov ntawv transgranular thiab intergranular.
(2) Cov kev ntxhov siab uas tshwm sim los ntawm kev ua haujlwm txias, superposition ntawm kev laus thermal kev nyuaj siab, thiab qhov kev nyiam tshaj plaws ntawm cov txheej txheej saum npoo ntawm cov txheej txheem thaum ntxov ntawm kev laus yog cov laj thawj tseem ceeb rau lub hnub nyoog tawg ntawm MonelK500 alloy.
(3) Kev ua haujlwm ncaj qha tom qab ua haujlwm txias yog qhov zoo rau kev so thiab kho cov kev ntxhov siab uas tshwm sim los ntawm kev ua haujlwm txias, thiab tuaj yeem tiv thaiv kev laus ntawm kev sib tsoo ntawm Monel K-500 alloy.
