1. Cov Khoom Txhais Lus thiab Cov Qauv Txheej Txheem
A31120 yog lub npe tsib caug {{1} Raws li cov yeeb nkab loj hauv cov kab ke NCOr Nws cov cwj pwm tseem ceeb thiab cov qauv muaj xws li:
Composition Tsim:
Nickel - chromium {}}}}}} (n nev }.0%) + Molybdenum Qhov Cuab (MO: 2.5-3.5%);
Ultra - Cov pa roj hmab qis (C Tsawg dua li 0.015%), thiab Boron tswj (B tsawg dua los yog sib npaug los yog sib npaug los ntawm hluav taws xob embriation;
Cov Qauv Siv: RCC {- m m3301 (GB / T 5310 Daim Ntawv Ntxiv Ntawm Nuclear) {3} Cov tseem ceeb} Cov Ntsiab Kev Ua Tau Zoo
Kev tiv thaiv hluav taws xob tiv thaiv: Elongation tswj hwm ntawm ntau dua lossis sib npaug rau 25% ntawm cov nruab nrab ntawm fluon flux ntawm 1 × 10²²n / cm ×;
Corrosion Kuj:
Thawj Circuit Court Dej Corrosion<0.0005mm/year (330°C/15.5MPa);
Hla lub Huey intergranular ntsuas (boiling 65% nitric acid);
High - kub lub zog: tawm lub zog ntau dua los yog sib npaug ntawm 350 qib tsim (60-xyoo tsim lub neej).
3. Raug kev cog qoob loo nuclearle
Cheebtsam Circuit Court:
Reactor siab rau lub taub hau nkag mus;
Tswj Qws tsav tsav tsheb tshuab foob rooj plaub;
Lub Nruab Kev Nyab Xeeb:
Niasurturizer fais fab riam lub tes tsho;
Kev txhaj tshuaj tiv thaiv kev nyab xeeb (SI) nozzle . 4. sib piv nrog cov ntaub ntawv zoo sib piv
vs. A690TT (inconel 690):
Siab dua npib tsib xee, 50% txhim kho kev nyuaj siab ntxhov siab corrosion cracking (SCC) tsis kam;
40% nqi siab dua, tab sis txuas ntxiv tsim lub neej rau 60 xyoo;
vs. z2Cnd18-12n (Fabkis qib neeg qib siab ntawm cov qib qis):
Molybdenum Qhov cuab lub zog muab kev txhim kho intergranular corrosion tsis kam (hu deey kuaj).
5. Kev Ua Lag Luam thiab Kuaj Cov Ntsiab Lus Tseem Ceeb
Nuclear Cov Ntawv Pov Thawj Nuclear Kev Ua Haujlwm: Nnsa {{0} Yuav tsum muaj daim ntawv pov thawj khoom siv ntaub ntawv;
Kev Kuaj Tshwj Xeeb:
Irradiation ntsuam xyuas (simulating 60 xyoo ntawm kev pabcuam);
100% kev sim ntsuas (PT) + ultrasonic sim (ut);
