Abstract
Particles of Zr3Si in a number of Zr-2.5Nb pressure tubes are found to exhi bit segregation of Fe and Nb to the Zr3Si/matrix interface. On oxidation be tween 553 and 673 K, an amorphous oxide of the silicide is formed. Neutron irradiation at 563 K resulted in no significant structural modifications to the silicide. The segregation of Fe and Nb to the silicide/matrix interfac e is retained after either oxidation or irradiation. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
