Commercial Mg extrusions usually develop various types of basal textures, affecting the formability and mechanical properties. According to Barbier et al. H. HOSODA, T. INAMURA, in Shape Memory Alloys for Biomedical Applications, 2009. The mechanisms for the formation of basal texture variations were systematically investigated for the first time based on the twinning and dynamic recrystallization (DRX) during extrusion using electron back-scatter diffraction (EBSD) characterization. the act of a person who encloses something in or as if in a casing or covering, a school giving instruction in one or more of the fine or dramatic arts, a comic character, usually masked, dressed in multicolored, diamond-patterned tights, and carrying a wooden sword or magic wand, Unabridged The undeformed material is assumed to have a basal fibre texture perpendicular to tension direction. Bracke et al. definition. Consider the (x,y) plane of the reference basis; its trace on the sphere is the equator of the sphere.We draw a line joining the South pole with the pole of interest P.. They also report that the texture strengthening is dominated by the contribution of slip which strengthens the {111} poles in the tensile direction. [88,163] studied the recrystallization texture of annealed cold rolled Fe-22%Mn-0.6%C (composition in wt.-%, γisf=15 mJ/m2). 4.14 shows the effect of rolling ratio on the deformation texture in a Ti-26Nb-3Al alloy [41]. Other orientations exist, but they do not change the overall texture significantly. This process resulted in small grain sizes. (b) Texture measurements locations. 4.10. Young's modulus of this alloy is lowest along the <100>, indicating that the elastic strain exhibits the largest value along the 45° from the RD (Kim H Y et al., 2006e, Inamura et al., 2005b). The results are summarized as follows: 1.6. 4.15 shows the ODF sections of φ2 = 45° for Ti-(19–29)Nb-2Zr-0.7Ta-1.2O alloys cold-rolled with a reduction of 98.5% in thickness [31]. Basal cell cancer is the most common form of cancer in the United States. If your language skills aren’t already top-notch, then this vocab quiz can get you up to speed! The intensity of the {001}〈110〉 component increases drastically with increasing Nb content reaching maximum at 23 at.% and then decreases with further increasing Nb content. A reduction in final grain size was observed after extrusion, the smallest grain size of Dmean = 8 μm occurring in AZ31-0.4 wt%Ce-0.8 wt%Ca after 250 °C extrusion. It is seen that the {001}〈110〉 is a dominant component and its intensity increases with increasing reduction ratio up to 97%. Diffraction, whether by X-rays or electrons, has been the traditional way to determine film crystallography and extent of texture. The initial alloy strategies emphasized the grain refining effect of alloy additions as well as the role of second phases in work-softening of the deformed alloys.

A variety of physical and mechanical properties depend on texture including elastic modulus, yield strength, magnetic permeability, etch rate, and diffusion. 1.3b). Table 10.1. The reduction in the Cu orientation is caused by mechanical twinning. One possibility is that first the Cu twin orientation, which is a consequence of the twinning of the Cu component, slips into the Goss orientation and eventually to the Brass orientation. We may thus imagine the involved grain boundaries separating grains that are tilted relative to one another. The solution-treated Ti–Nb–Al exhibits a recystallization texture of the {112}β<011>β type by a subsequent heat-treatment at 1273 K for 1.8 ks. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. They found a recrystallization texture which was almost identical to the cold rolled texture, except for a marginal increase of the Goss-{110}<100> component in the recrystallized steel. Grain growth and the formation of recrystallization twins did not have a statistically-relevant effect. Of course, one must consider that some of the HABs may be formed as a result of GNBs, discussed earlier. Rare and alkaline earths that are surface active in Mg and which can refine the grain structure and the microstructure9–11 have been used for micro-level alloying of AZ31. Recrystallization textures are discussed in Chapter 11. KIM, S. MIYAZAKI, in Shape Memory Alloys for Biomedical Applications, 2009. 1. This can occur even when the heterogeneous nucleation and growth stages of primary recrystallization do not occur. Recently, it has been shown that twin-roll-cast (TRC) AZ31 sheet can develop weaker textures upon annealing due to the metastable cast/deformed structure of TRC.8,9. translation and definition "basal melting", Dictionary English-English online. 4.14.
