Abstract
Precipitation characteristics of the Mo-added Zr-alloy were studied by TEM after annealing at 590℃ up to 32 hours. Mo addition was found to decrease the size and to increase the volume fraction of precipitates, and to suppress the grain growth in Zr-1Nb-1Sn-0.1Fe alloy. (Zr,Nb)₄ Fe precipitate was observed in Mo-free Zr-alloy, while ZrNbMoFe type precipitate was found in Mo-added Zr-alloy.
