Qhov sib txawv tiag tiag ntawm Nimonic 75 (solid solution) thiab Nimonic 80A
Qhov sib txawv tiag tiag ntawm Nimonic 75 thiab Nimonic 80A yog nyob rau hauv lawv cov qauv metallurgical thiab hardening mechanism, uas txiav txim siab lawv qhov muaj zog thiab kev siv zoo tagnrho. Txawm hais tias ob qho tib si yog npib tsib xee-chromium raws li alloys, Nimonic 75 yog ib qho kev daws teeb meem zoo- ntxiv dag zog rau kev ua kom zoo, thaum Nimonic 80A yog nag lossis daus-cov hlau alloy tsim kom muaj kev ntxhov siab thiab siab - qhov kub thiab txias.
NIMONIC 75 yog dab tsi?
Nimonic 75 yog npib tsib xee-chromium alloy nrog zoo corrosion kuj thiab kub kuj, thiab nws kuj muaj ntxiv titanium thiab carbon. Keeb kwm siv nyob rau hauv 1940s rau kev tsim turbine hniav, Nimonic 75 yog ib qho yooj yim rau tshuab thiab vuam, thiab yog tam sim no ntau lug siv nyob rau hauv roj turbines, industrial furnaces, thiab nuclear engineering.
1. Nimonic 75 Taw qhia
Nim 75yog high -kev ua tau zoo nickel-chromium alloy. Nimonic 75 nthuav tawm cov khoom siv kho tshuab zoo, qis qis, thiab siab -kub oxidation tsis kam. Titanium yog ib qho tseem ceeb hauv kev txhim kho lub zog tag nrho ntawm cov hlau.
Nimonic 80A Taw Qhia
Nimonic 80Ayog lub hnub nyoog -nickel hardening-chromium alloy. Cov hlau no yog tsim los ntawm cov txheej txheem nag lossis daus nrog kev sib ntxiv ntawm titanium thiab txhuas. Alloy 80A nthuav tawm zoo heev corrosion kuj, siab tensile zog thiab creep rupture zog, thiab zoo oxidation kuj.
