摘要：

The effect of quenching, and cold working after quenching, on the corrosion resistance of a Zr-1Nb alloy has been investigated both in 360 degrees C, 18.6 MPa high temperature water and in 500 degrees C, 10.3 MPa high temperature steam. The corrosion mechanisms have been analysed. It is found;that quenching not only from the alpha+beta two - phase region, but also from the beta single - phase region seriously weakens the corrosion resistance both in high temperatue water and high temperature steam. The corrosion resistance does not improve with aging for 16 h/450 degrees C, However, cold working between quenching and aging can significantly improve the corrosion resistance because of its affect on the distribution of the alloying element Nb.
