Modeling of continuous dynamic recrystallization in commercial-purity aluminum

Recrystallization Behavior of Commercial Purity Aluminium Alloys

3D reconstruction of microstructure in a commercial purity aluminum

The topic of reconstruction of polycrystalline microstructures is briefly reviewed. An example is given of using orientation maps to reconstruct digital microstructures with a representation of a polycrystal structure that includes crystallographic orientation information. The method uses packing of ellipsoids to approximate the grain structure, coupled with Voronoi tessellation. For the exampl...

Observation of recovery and recrystallization in high-purity aluminum measured with forward modeling analysis of high-energy diffraction microscopy

High-energy X-ray diffraction microscopy is a non-destructive materials characterization technique that is capable of tracking the evolution of three-dimensional microstructures as they respond to external stimuli. We present measurements of the annealing response of high-purity aluminum using the near-field variant of this technique. The data are analyzed with the forward modeling method which...

Ultrasonic Monitoring of Recrystallization Textures in Aluminum

The present paper is an attempt to use ultrasonic velocity measurements to characterize the texture of an aluminum-magnesium alloy ( Al 5xxx ) and to compare the results with orientation imaging microscopy ( OIM ) results. The results are characterized in terms of three orientation distribution coefficients ( ODC's ), W400 , W420 , and W440 , each of which describes a particular forming anisotr...

A Method of Measuring Stored Energy Macroscopically Using Statistically Stored Dislocations in Commercial Purity Aluminum

Stored energy from plastic deformation in rolled aluminum has been quantified with both macroscopic and microscopic methods. Differential scanning calorimetry (DSC) and Microhardness tests were used to determine a value for stored energy based on energy released during recrystallization and resistance to plastic flow from the accumulated dislocation content, respectively. For a value of stored ...
