Abstract

Abstract

Microstructure of hot extruded tube was studied by TEM,EDS and SEM equipped with EBSD.The results showed that elongated structure with some recrystallized grains and sub-grainboundaries was formed after extrusion.The second phase particles（SPPs）,distributed randomly,was confirmed as β-Zr with a small quantity of β-Nb and Zr-Fe-Nb type precipitates.
