Abstract

The textures that develop in a 5182 aluminum alloy as a result of monotonic high-temperature compression have been investigated. The authors found that the deformation texture was a function of temperature. For compressive deformation at 300 C and below the material formed the classic (101) deformation texture, while the material develops a texture that is a combination of the classical uniaxial compression deformation texture, (101), and static recrystallization texture, (001), as a result of the deformation alone when the deformation temperature was at and above 400 C. The investigation has focused on determining the mechanism responsible for the development of this unusual progression of deformation textures. In addition the authors have performed orientation imaging microscopy (OIM) to identify the shapes of grains with particular orientations and grain-to-grain orientation relationships. The conclusions are summarized as follows: The texture development is not a result of static processes, i.e. static recrystallization at the various hold times altered neither the textures nor the constitutive behavior. Simulation using a crystal plasticity model indicates that the combination of a cube component prevalent in the original texture, slip activity on 011 planes, and increased rate sensitivity leads to a combined (001) and (101) texture. Finally, the microscopicmore »« less

Plastic deformation of CVD textured tungsten; 1: Constitutive response

Journal Article Subhash, G; Lee, Y; Ravichandran, G - Acta Metallurgica et Materialia

The constitutive response of CVD textured tungsten in <001>, <011> and random orientations under uniaxial compression subjected to a range of strain rates is investigated. Both <001> and <011> textured specimens revealed a strong strain rate sensitivity. The <001> specimens showed large ductility at all strain rates and significant strain softening during high strain rate deformation. The <011> texture undergoes homogeneous deformation under quasi-static loading but failed prematurely due to extensive grain boundary cracking during high strain rate loading. The random orientation specimens exhibited brittle failure. The temperature rise during high strain rate deformation was measured using high speed infraredmore »« less

Plastic deformation of CVD textured tungsten; 2: Characterization

Journal Article Subhash, G; Lee, Y; Ravichandran, G - Acta Metallurgica et Materialia

Deformation and failure modes of CVD textured tungsten in <001>, <011> and random orientations subjected to various loading rates under uniaxial compression are characterized using optical and electron microscopy. It is found that <001> orientation undergoes large homogeneous deformation in the range of strain rates investigated (10{sup {minus}}3{minus}10{sup 4}/s). Evolution of dislocation substructure in <001> tungsten is characterized by TEM studies. Under quasi-static loading rates, elongated dislocation cell formation is observed. At high strain rates, the dislocation density initially increases with respect to strain and then saturates when the temperature rise due to adiabatic heating becomes significant. At true strainsmore »« less

Influence of particle stimulated nucleation on the recrystallization textures in cold deformed Al-alloys. Part 2: Modeling of recrystallization textures

Journal Article Engler, O - Scripta Materialia

As discussed in Part 1 of this study, the recrystallization textures of particle containing Al-alloys, in which recrystallization is controlled by PSN, are all very similar. They generally are rather weak which indicates they comprise a high fraction of randomly oriented grains, but they also depict a characteristic ND rotated cube-orientation with the approximately Miller-indices {l_brace}001{r_brace}<310> and, at deformations exceeding 90%, the P-orientation {l_brace}011{r_brace}<122>. It turned out that under certain circumstances the typical PSN-textures may depict intensities as high as f(g) > 10, which means that the general description of PSN recrystallization textures as being random is oversimplified.

Development of recrystallization texture and microstructure in cold rolled copper

Conference Necker, C; Doherty, R; Rollett, A

Oxygen free electronic copper, 99.995% purity, of two initial grain sizes, 50 {mu}m and 100 {mu}m, has been cold rolled to six strains of 1.0, 1.5, 2.0, 2.65, 3.5 and 4.5 (von Mises equivalents). The rolled materials were partially and fully recrystallized to study the development of recrystallization textures as a function of grain size, strain and fraction recrystallized. The initial textures were relatively random and the deformation textures show the classic {beta} fiber development. As strain is increased both materials produce increasingly intense cube recrystallization textures, (100)<001>, as measured both by x-ray diffraction and the electron backscatter pattern (EBSP)more »« less

Texture and microstructure development in Al-2%Mg during high- temperature deformation

Conference Chen, S; Kocks, U

The high rate sensitivity of the flow stress that is exhibited by alloys under solute drag control, such as Al-Mg at high temperatures, influences texture development because more slip systems contribute to deformation. Al-2% Mg was tested in channel-die compression, i.e. idealized rolling, at 290{degree}C and 400{degree}C, at strain rates from 10{sup {minus}1}/s to 10{sup {minus}5}/s. The texture development in rolling predicted by polycrystal plasticity simulation indicates that the brass component increases while the copper component decreases when the rate sensitivity is raised. The experimental results are in good agreement with this prediction. In addition, cube component appears when microstructuralmore »« less
