Abstract
Atomic mass transport behavior of carbon in two-phase Nb-lZr-0.1C alloy under a temperature gradient was investigated using a radioactive tracer technique. Samples were heated in different temperature ranges for various times to study the effects of temperature and time on the development of carbon concentration profiles. The direction of carbon transport in the Nb-lZr0.1C alloy heated below the solvus of carbon is toward the colder regions, which is a reversal from that in the Nb-lZr-C solid solution alloys. A one-phase region develops in the hotter portion of an initially two-phase sample, and the concentration profile therein approaches that of steady state upon prolonged heating.
