Transformation from glassy + β-Zr to glassy + icosahedral structure in Zr-based alloy

摘要

The phase transformation of the mixed "glassy + submicron β-Zr solid solution particles" structure in Zr_(65)Ni_(10)Al_(7.5)Cu_(7.5)Ti_5Nb_5 on heating is studied. bcc β-Zr solid solution particles dissolve in the glassy phase while the nanoscale particles of the icosahedral phase precipitate after the completion of the first exothermic reaction.
