Microstructure, Texture and Mechanical Properties Anisotropy of Ni-16Cr and Ni-16Cr-16Mo Solid Solution Alloys in Hot Rolled and Annealed Condition

Abstract

Present work describes microstructure-texture-mechanical property anisotropy correlation of Ni-16Cr and Ni-16Cr-16Mo alloys in hot rolled and annealed condition. The high and low SFE values associated with Ni-16Cr and Ni-16Cr-16Mo alloys result in partial recrystallization after recovery and presence of twins in recrystallized grains, respectively. Both the alloys display two-slopes in the true plastic stress-strain curves and follow Ludwigson relation. However, the deformation mechanisms of both the alloys are different. Sample orientation dependent ductility of these alloys has been explained based on dislocation storage capacity and dynamic recovery coefficient using Kock-Mecking-Estrin analysis. © 2015 Elsevier Ltd.
