This pole figure measurements have been performed on a 300 mm long Fe-Mn-Al-Ni-Ti bar with a diameter of 6.3 mm consisting of two abnormally grown grains. The investigated lattice plane 211 of the present body centered cubic (BCC) phase was measured using a cobalt anode at theta = 98° on the diffractometer Seifert XRD 3003 Micro operated at 40 kV and 35 mA, equipped with a monochromator in the secondary beam paths and a polycapillary with a beam size of 2 mm in diameter in the primary beam path.
