Investigation of Deformation Induced Disorder and Re-Ordering by Subsequent Annealing in Ni3Al+B

Abstract

The change of the degree of order with increasing rolling reduction was determined by X-ray diffraction. During a subsequent isochronal annealing treatment between 273 K and 1473 K of 40% rolled samples, hardness, yield-stress and the intensities of the superlattice reflections were measured and the microstructural evolution was investigated by TEM. The correlation between the measured property changes are discussed.
