摘要：
The atomic order of the metastable beta phase influences on the characteristics of the martensitic transformation in Cu-Al-Ni shape memory alloys. On the other hand, the pro-eutectoid gamma(1) precipitation and the eutectoid decomposition produce deleterious effects in the martensitic transformation. In this work, the Rietveld analysis performed on neutron diffraction spectra allows to determine the order, the volume fraction of the different precipitated phases and their evolution during heating in a Cu-14.37Al-4.2Ni (wt%) shape memory alloy.
