By 3 dimensional X-ray diffraction (3DXRD) using high energy X-rays from synchrotron sources it is possible to study in-situ the nucleation and growth during recrystallization. In this paper it is described and discussed how 3DXRD can supplement EBSP measurements of nucleation and growth. Three types of studies are considered: i) orientation relationships between nuclei and parent deformed matrix, ii) recrystallization kinetics of individual bulk grains and iii) filming of growing grains in deformed single crystals.

The decomposition of Al-rich Al-Ag-alloys quenched from the solid solution (α) and aged within the metastable miscibility gap, follows the sequence GP zones → γ' → γ (Ag2Al). Nearly spherical GP zones (Guinier-Preston zones) coherent with the fee matrix are formed by homogeneous nucleation and growth, whereas γ' plate-like precipitates with an hdp structure — lying on {111}-planes of the fee matrix — nucleate heterogeneously at dislocations after a certain incubation time. In the present work HREM was used to investigate the internal structure of the GP zones.Single crystals of Al-3 at.% Ag grown by strain-annealing were cut along (110) by spark erosion. The samples were homogenized for 2 h at 580°C prior to ageing for 43 h at 160°C. They were electrolytically thinned at −30°C in a methanol-HNO3 (2:1) solution. The TEM work was performed on a Philips CM 30 fitted with a Super Twin Lens and a double tilt holder. To bring the electron beam parallel to the optical axis the coma-free alignment was used. At 300 kV the instrumental point resolution was determined to be 1.9 Å using the Young’s fringes method.
