Qhov cuam tshuam Toughness ntawm Monel Alloys
Cov yam ntxwv tshwj xeeb ntawm kev ua haujlwm yog raws li hauv qab no:
Kev cuam tshuam toughness hloov pauv ntawm qhov kub thiab txias
Tsis zoo li cov pa roj carbon steel thiab qee qhov qis- alloy steels uas nws qhov cuam tshuam qhov hnyav poob qis thaum qhov kub thiab txias poob qis dua cov khoom siv hluav taws xob- qhov kub thiab txias hloov pauv, Monel alloys (xws li Monel 400 thiab K-500) muajtsis pom tseeb ductile-kub hloov pauv hloovnyob rau hauv qhov kub thiab txias ntawm chav tsev kub mus rau-253℃(kua hydrogen kub). Lawv qhov cuam tshuam toughness tseem nyob rau theem siab lossis qhia tau tias nce me ntsis nrog txo qhov kub thiab txias.
Piv txwv li, Charpy V-notch impact toughness of Monel 400 at room temperature is about 180–220 J. Thaum qhov kub poob mus rau -196℃(kua nitrogen kub), nws qhov cuam tshuam toughness tseem tuaj yeem khaws cia siab tshaj 150 J, deb tshaj qhov tsawg kawg nkaus toughness yuav tsum tau rau cov khoom siv.
Hauv paus ua rau tsis kam mus rau qis -kub embrittlement
Monel alloys yogib zaug -theem ntsej muag-centered cubic (FCC) cov kua tshuaj alloysyog tsim los ntawm nickel thiab tooj liab. FCC siv lead ua qauv muaj ntau lub tshuab plam, uas tuaj yeem ua tau zoo rau cov yas deformation txawm tias qhov kub thiab txias tsis tshua muaj, zam qhov tawg tawg los ntawm kev txwv ntawm kev txav txav. Hauv qhov sib piv, cov hlau nrog lub cev -centered cubic (BCC) cov qauv (xws li cov pa roj carbon zoo tib yam) muaj qhov cuam tshuam rau qhov ntsuas qhov ntsuas kub ntawm qhov kub qis, ua rau muaj qhov hnyav poob qis.
Kev siv engineering cuam tshuam
Qhov zoo heev uas tsis tshua muaj -kub toughness ntawm Monel alloys ua rau lawv nyiam cov khoom siv rau cryogenic engineering, xws liLiquid Natural Gas (LNG) khaws cia thiab cov khoom siv thauj mus los, kua hydrogen / kua oxygen roj system Cheebtsam ntawm foob pob ua ntxaij, thiabqis-kub li qub thiab cov kav dej hauv cov tshuab ua kom txias txias. Lawv tuaj yeem ua kom muaj kev ncaj ncees thiab kev nyab xeeb ntawm cov khoom nyob rau hauv ntev -lub sij hawm qis - qhov kub thiab txias kev pab cuam.
