Description
A method for analyzing the contents of Fe and Cr in the matrix of Zircaloy-4 specimens has been developed by means of quantitative metallography and calculation in theory. This indirect measurement method has been found to be acceptable for determining Fe and Cr contents in the matrix of Zr-4 as long as the more exact volume fraction of second phase particles could be measured. The three specimens with different heat treatment history were analyzed. It has been found that there are the different volume fraction of second phase particles Zr(Fe, Cr)2 and the different Fe and Cr contents in matrix among three specimens, and the similar size of second phase particle. It is also considered that the main factor affecting the corrosion behavior of Zr-4 is the solute contents in matrix rather than the size of second phase particles
