X-Ray diffraction studies on asymmetrically broadened peaks of heavily deformed Zirconium based alloys
A. Sarkar, P. Mukherjee, P. Barat
The diffraction peaks of Zircaloy-2 and Zr-2.5%Nb alloys at various deformations are found to be asymmetric in nature. In order to characterize the microstructure from these asymme…
