摘要
Precipitation kinetics in hot-deformed Nimonic 80a alloys is investigated by small-angle neutron scattering. The integrated intensity increases faster and the average size of the precipitates is generally smaller in the deformed alloy as compared to an undeformed reference sample. It is shown that small carbide precipitates contribute considerably to the SANS signal from Nimonic 80a. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
