Abstract

Kanzaki force induced by substitutional solutes was introduced as a composition-dependent oscillating defect field in the Ginzburg-Landau model to simulate the pre-transition structure preceding the b-to-x phase transformation. A three-dimensional (3-D) modulated incommensurate structure of the x phase composed of alternating x and b phases was predicted to be present in the moderately concentrated Zr-Nb alloys. The modeling work suggests that the Kanzaki force acts as a resistance that generates and retains the incommensurate structure of the x phase.
