Abstract
The evolution of aggregates formed from an amorphous hydrogenated CuTi alloy has been measured by small-angle neutron scattering as a function of temperature. The total correlation function has been used to determine both fractal dimension D and crossover length ξ which are found to increase with temperature. The temperature range studied can be divided into three regions corresponding respectively to the formation, restructuration, and growth of the aggregates. This evolution is related to the variation of the hydrogen content and to its mobility inside the sample.
