Inconel yog Suav transliteration ntawm English Inconel. Qhov tseeb, qhov no yog lub npe sau rau ib pawg ntawm austenitic superalloys raws li nickel thiab chromium.
Inconel series yog thawj zaug tsim nyob rau hauv 1940s raws li cov khoom tsim los ntawm Wiggin Alloys hauv Hereford, England, los txhawb kev tshawb fawb txog Whittle lub dav hlau dav hlau.
Cov nroj tsuag tom qab tau txais los ntawm American Special Metals Corporation.
Cov yam ntxwv ntawm Inconel
Inconel muaj cov yam ntxwv zoo sib xws rau Hastelloy, lossis yog vim li cas super alloys hu ua "super": lawv tiv taus oxidation thiab corrosion dua li lwm yam khoom siv hlau.
Thaum cov khoom siv hlau zoo ib yam (xws li hlau, txhuas, thiab lwm yam) raug rau qhov kub thiab txias, qhov tsis xws ntawm lattice feem ntau pib tshwm sim hauv cov khoom siv lead ua, uas ua rau muaj kev ntxhov siab heev. Nyob rau hauv layman cov ntsiab lus, qhov no txhais tau hais tias nyob rau hauv high kub, lub zog ntawm cov qauv yog txo, ua rau cov khoom tsim los poob lawv cov thawj functions.
Cov yam ntxwv thiab cov qauv ntawm Inconel alloy
Corrosion kuj:
Thaum Inconel yog rhuab, qhov saum npoo ntawm lub alloy yog passivated los ua ib tug tuab thiab ruaj khov passivation oxide txheej, tiv thaiv sab hauv ntawm cov hlau los ntawm corrosion.
Kub kub kuj:
Ntau hom Inconel siv cov tshuaj tiv thaiv kom muaj zog lossis nag lossis daus hardening mechanisms kom tswj tau cov khoom zoo ntawm qhov kub thiab txias. Inconel tuaj yeem tswj tau cov khoom siv kho tshuab zoo tshaj qhov kub ntau.
Qhov no ua rau Inconel haum rau siv nyob rau hauv ntau yam kub, siab siab thiab hnyav ib puag ncig. Qhov no yog ib yam dab tsi uas cov khoom siv hlau zoo li cov hlau thiab txhuas tsis tuaj yeem ua tiav.
advi ua
1. Hauv thev naus laus zis, Inconel qee zaum hu ua "Inco" (lossis tsis raug "iconel"). Cov npe lag luam feem ntau rau Inconel 625 alloy suav nrog:
Inconel 625, Chronin 625, Altemp 625, Haynes 625, Nickelvac 625 thiab Nicrofer 6020, thiab lwm yam.
2. Cov qauv sib txawv ntawm Inconel muaj cov tshuaj sib txawv heev, tab sis txhua tus ntawm lawv yog tsim los ntawm npib tsib xee, thiab qhov thib ob yog ua los ntawm chromium.
3. Rau cov Inconels no, uas siv los nag lossis hnub nyoog ntxiv zog raws li lub zog ntawm lub zog, me me ntawm niobium thiab npib tsib xee ua ke los ua ib qho intermetallic compound Ni3Nb hu ua 'theem.
Lub 'theem yuav loj hlob mus rau hauv me me cubic unit cell, zoo tiv thaiv plam thiab nkag ntawm qhov kub thiab txias. Lub 'theem nce nrog lub sij hawm, tshwj xeeb tshaj yog tom qab 3 teev ntawm kev raug thermal ib puag ncig ntawm 850 degree, thiab txuas ntxiv nce tom qab 72 teev ntawm raug.
Qhov no yog lub hauv paus ntsiab lus ntawm Inconel tsis kam mus rau qhov kub thiab txias.
Hom kev siv thiab kev ua haujlwm
Hauv qhov teeb meem tom ntej no, peb yuav qhia koj txog daim ntawv thov kev paub ntawm Inconel alloys, suav nrog cov qib tseem ceeb ntawm Inconel alloys, nrog rau kev siv cov yam ntxwv, kev sib txuas, machining thiab lwm yam.
Raws li lub superalloy, Inconel tsis tsuas yog sawv cev rau qib siab tshaj plaws hauv kev tsim cov khoom siv raw, tab sis nws tsim nyog ua thiab siv kuj tseem ceeb heev.
