摘要：

The correlation between the tensile strength and corrosion behavior of Zr-1.0wt%Nb alloy heat treated at 480 degrees C for up to 32 hours was evaluated. The tensile strength at 400 degrees C was continuously reduced with an increasing heat treatment time, mainly due to a grain growth and a decreased area fraction of the precipitates. However, the corrosion resistance in an aqueous ammonia solution at 360 degrees C was enhanced, mainly due to the formation of beta-Nb precipitates. It is thus concluded that a longer heat treatment time provides a better corrosion resistance while degrading the tensile strength.
