1.Qhov: Dab tsi yog cov ntsiab lus tseem ceeb hauv N07718 (Inconel 718) Stainless hlau daim hlau thiab kav dej, thiab lawv ua li cas txhawb nws cov khoom?
Teb: N07718 feem ntau muaj npib tsib caug (50-55%), chromium (4.8-3%), thiab sib npaug ntawm titanium thiab txhuas. Niobium thiab molybdenum txhim kho siab kub-kub lub zog thiab cov chromium muab cov corrosion tsis kam. Titanium thiab Aluminium Daim Ntawv Intermetallic nag los nag dab tsi uas txhawb nqa cov matrix, ua rau nws haum rau ib puag ncig.
2.Quion: Dab tsi yog qhov kev ua haujlwm siab tshaj plaws rau N07718 daim hlau thiab kav dej, thiab lawv ua li cas lawv ua nyob rau hauv thermal cycling?
Teb: N07718 can operate continuously at temperatures up to 650℃(1200℃F) and intermittently at higher temperatures up to 800℃(1472℃F). Nws ua kom pom cov khoom siv hluav taws xob zoo heev thiab tiv thaiv kom sov cycling, tswj hwm nws cov khoom siv tshuab txawm tias tom qab muab cua sov ntxiv thiab txias dua. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov zoo li cov roj av tshuab thiab tshuab hluav taws xob.
3.Quion: Dab tsi cov txheej txheem fabrication yog qhov haum rau n07718 daim hlau thiab kav dej, thiab puas muaj cov kev cov nyom tshwj xeeb?
Teb: N07718 tuaj yeem muab welded siv cov txheej txheem zoo li Tig thiab Mig vuam, tab sis nws yuav tsum tau kho cua sov kom tiv thaiv kom tsis txhob tawg vim nws lub zog siab. Machining yog ua tau tab sis xav qeeb qeeb thiab ntse cuab tam vim nws txoj haujlwm ua haujlwm hnyav. Txoj kev sib sau tau nyob rau hauv chav tsev kub rau cov duab ntsuas kub, txawm tias kev sib tw kub kom tsis txhob muaj ntau txoj hlab ntshav kom tsis txhob muaj kev tawv nqaij ntau dhau.
4.Qhov: Cov kev siv muaj kev lag luam feem ntau siv siv N07718 daim hlau thiab kav dej, thiab vim li cas lawv nyiam dua lwm cov alloys?
Teb: Lawv tau siv dav hauv Aerospace (dav hlau cav Shafts, roj thiab roj av (cov khoom siv hluav taws xob, thiab cov nkoj siv hluav taws xob (cov nkoj siab). Lawv nyiam stems los ntawm kev sib xyaw ua ke ntawm lub zog siab, xeb tawm tsam ntau yam, ua kom muaj ntau yam ntawm nockel alloys hauv cov xwm txheej huab.
5.Qhov: Dab tsi cov qauv thoob ntiaj teb N07718 daim hlau thiab kav dej, thiab cov ntawv pov thawj zoo yog li cas?
Teb: N07718 daim hlau thiab kav dej ua tiav nrog cov qauv xws li ASTM B637 (rau cov pob zeb, thiab cov ntawv txheeb (rau seamel tsis muaj txiv kav). Cov ntawv pov thawj cov ntaub ntawv koom tes suav nrog cov ntaub ntawv xeem ntawv (MSTRS) ib ASTM ET413, ISO cov khoom siv tshuaj lom neeg raug, thiab cov cuab yeej ua si txhua yam.
