Electron crystallography applied to the structure determination of Nb(Cu,Al,X) Laves phases.
The presence of primary precipitates of the Laves phases considerably improves the mechanical properties and the resistance to thermal degradation of the high-temperature shape memory Cu-Al-Nb alloys. The structure analysis of the Laves phases was carried out on particles contained in the ternary and quaternary alloys as well on synthesized compounds related to the composition of the Nb(Cu,Al,X)(2) phase, where X = Ni, Co, Cr, Ti and Zr. The precise structure determination of the Laves phases was carried out by the electron crystallography method using the CRISP software.
