Title: Distribution of carbon, nitrogen, and oxygen in heavy-ion irradiated vanadium and some vanadium alloys. [Heavy ion irradiation]

Abstract

The depth distribution of C, N, and O was measured in the damage layer of a series of heavy-ion irradiated samples of V and V alloyed with C, O, N, Cr, or Ti. Ion-beam analysis using the simultaneously induced nuclear reactions /sup 12/C(d,p/sub o/)/sup 13/C, /sup 16/O(d,p/sub l)/sup 17/O, and /sup 14/N(d,..cap alpha../sub l/)/sup 12/C provided the C, N, and O distributions to a depth of 2 ..mu..m. The profiles were studied as a function of irradiation temperature and displacement dose produced by MeV V or Ar ions. Displacement dose rates of approx.3 x 10/sup -3/ dpa/s provided peak-damage doses of up to approx.30 dpa, at irradiation temperatures between 250 and 880/sup 0/C. The dominant effect observed was a large enrichment of C, up to approx.20 times the bulk C concentration, in the damage zone of most of the irradiated samples. The C enrichment occurred between approx.400 and approx.700/sup 0/C, and increased with irradiation dose. A similar enrichment of C occurred on the sample surface over the same temperature range. The surface C enrichment was associated with V/sub 3/C precipitates on the sample surface, while the damage-zone C enrichment was associated with an irradiation-induced coherent )012) habit-plane precipitate.
