Metallographic study of abnormal grain growth during aging of a /beta/-quenched Zr-1.14 wt% Cr-0.08 wt% Fe alloy
Description
Certain quenching rates, which produce a mixed martensitic-Widmanstaetten structure, should be avoided during the fabrication of fuel sheathing, since recrystallization and grain growth occurs at a much lower temperature than a material quenched at such a rate that the structure is wholly Widmanstaetten or wholly martensitic. Preaging at 350 or 450/degree/C prior to the high-temperature (700-750/degree/C) aging reduces the incidence of recrystallization and grain growth. 15 refs
