FAQ
Q1: Puas yog Nimonic 75 ua nkig tom qab ntev - kev pabcuam ntawm 800 degree?
A:No. Nimonic 75 yog asolid-kev daws teeb meemhlau alloy. Nws microstructure yog inherently ruaj khov. Tsis zoo li lub hnub nyoog- cov khoom siv tawv tawv (xws li Nimonic 80A), nws tsis muaj kev "tshaj- laus" lossis poob ntawm cov ductility thaum lub sijhawm.
Q2: Nimonic 75 puas tuaj yeem siv rau hauv qhov chaw siab - cua txias?
A:Yog lawm. Nimonic 75 tswj kev ua haujlwm zoo heev. Txawm li cas los xij, rau qhov siab heev -siab rotating qhov chaw, peb xav komNimonic 80Arau nws siab dua creep zog. Rau cov uas tsis yog- tig cov kav dej, Nimonic 75 yog qhovtus nqi feem ntau -kev xaiv zoo.
Q3: Dab tsi yog qhov txiaj ntsig ntawm Titanium (Ti) cov ntsiab lus?
A:0.2-0.6% Titanium ntxiv ua raws li cov nplej refiner. Nws pins cov ciam teb, tiv thaiv lawv los ntawm kev txav thiab coarsening nyob rau hauv high tshav kub, uas yog lub ntsiab yog vim li cas Nimonic 75 outlasts generic nickel alloys.
