摘要：

The precipitation behavior of second phase particles (SPPs) of Zr-Sn-Nb-Fe-Cr-Cu alloy after 6% and 12% pre-compressed deformation during aging was investigated by scanning electron microscope (SEM) and transmission electron microscope (TEM). The results show that the pre-deformation has a marked influence on precipitation behavior of Zr alloy. The average size of SPPs of 12% pre-compressed deformation samples is about 10 nm larger than that of 6% pre-compressed deformation samples, and the average size of SPPs is linearly inversely proportional to the volume fraction of pre-deformation when the alloy is aged at 600 degrees C. From TEM observation, the precipitates of orthorhombic Zr3Fe containing Cu element are detected when Zr alloys are aged at 550 degrees C for 30 min; the precipitates of hexagonal Zr(Fe, Nb)(2) are also found with smaller size to Zr3Fe when the aging time is prolonged to 1800 min. The pre-deformation has no remarkable impact on the type of SPPs.
