متن کاملMicrostructural evolution during recrystallization in hot rolled Aluminum Alloy 1050
The evolution of texture as a function of recrystallization has been characterized for hot-rolled AA1050. Samples prepared from a hot rolled sheet were annealed isothermally for sufficient time to allow complete recrystallization. The spatial orientation variation within the deformed microstructure of nucleation, growth and orientations of recrystallized grains is examined. The microstructural ...
متن کاملDynamic Recrystallization by Necklace Mechanism During Hot Deformation of 316 Stainless Steel
The aim of this study is to investigate the nucleation of new grains by necklacing mechanism during dynamic recrystallization (DRX). The material used is 316 stainless steel. In order to modeling the deformation behavior during hot rolling, one-hit compression tests were performed at temperature range of 950-1100 °C with strain rates of 0.01-1s-1. The result shows that at the tempera...
متن کاملDiscontinuous Dynamic Recrystallization during Accumulative Back Extrusion of a Magnesium Alloy
The study of nucleation mechanism of new grains during severe plastic deformation of magnesium alloys is of great importance to control the characteristics of final microstructures. To investigate the role of discontinuous recrystallization, a wrought AZ31 magnesium alloy was deformed by accumulative back extrusion process at 330 °C. The obtained microstructures were studied using optical and...
متن کاملDynamic Recrystallization under Hot Deformation of a PH Stainless Steel
Dynamic recrystallization, DRX, behaviour of a precipitation hardened, PH, stainless steel was studied in connection with microstructural developments in a compression test. The experimental results showed that the dominant mechanism of softening is DRX, but at high strain rates and low temperatures, ie, high Zener-Holman parameter, Z, work hardening and dynamic recovery, DRV, produced a pancke...
