Zirconium Niobium Alloy Qws
Zirconium Niobium Alloy Qws
FANMETAL muab Zirconium Niobium Alloy Qws UNS Qib R60904.
Zr-2.5Nb (Qib R60904) yog binary alloy nrog niobium kom muaj zog. Cov hlau tau raug siv rau cov raj siab hauv CANDU reactors.
Zirconium Niobium Alloy Qws, binary alloy raws li zirconium thiab ntxiv cov ntsiab lus niobium, lub hauv paus muaj pes tsawg leeg yog Zr-1 feem pua Nb thiab Zr-2.5Nb feem pua. Nws muaj corrosion kuj zoo rau acids, alkalis thiab ntsev. Nws muaj qhov zoo corrosion kuj thiab txhua yam khoom rau qhov kub thiab txias thiab dej siab thiab chav ntawm 300-400 degree .
