Abstract

‘White’ synchrotron radiation topography has been employed to reconstruct almost complete, though slightly shape distorted topographs of polycrystalline samples. Those used in the experiments were commercial (110) Fe-3wt%Si crystals containing several misorientated subgrains and were of thickness between 0.15 and 0.20 mm.

The topographs were reassembled ‘jig-saw puzzle’ fashion from photographically enlarged subgrain mini-topographs located near the centres of each film. Magnetic domains were observed in several subgrain topographs recorded in the Laue-reflection and Laue-transmission modes.

The technique emphasizes one of the advantages in using ‘white’ synchrotron radiation to produce rapid high resolution topographs of polycrystalline samples in relatively hazard free radiation conditions.
