摘要
The Co-59 nuclear magnetic resonance technique was used to investigate a set of melt-spun Cu85Co15 ribbons heat-treated at different temperatures. In the as-cast sample the grains are very small and the contribution of the surface prevails over the bulk. Heat treating the samples, the contribution of the bulk FCC Co grows and for temperatures around 500 degreesC, a small amount of HCP Co seems also to be present. (C) 2001 Elsevier Science BY.
