A Four Zones With Different Grain Size Distribution Along The Billet Download scientific diagram | a four zones with different grain size distribution along the billet section. grain size distribution of exp 1 (b to e) for single step on left side and (f to i) for. Based on the variation in grain size distribution, four different zones were found, as shown in fig. 5a. first, coarse grains were found at the top of the central line (fig. 5 b). then, 1.5–2 mm below this zone, a grain growth occurred (fig. 5 c) until the midsection of the billet, where the grain size started to reduce (fig. 5 d), and.
A Four Zones With Different Grain Size Distribution Along The Billet The grain sizes in the ii w and iii w zones are relatively smaller, but the grain size distribution in the ii w zone is more uniform, while there are individual coarse grains in the iii w zone. the average grain size and aspect ratio of each zone are shown in fig. 6 (e) and (f). as is seen, the average aspect ratio in the i–w zone is. Direct chill (dc) casting billets of an aa7050 alloy produced with different melt feeding schemes and casting speeds were examined in order to reveal the effect of these factors on the evolution of microstructure. experimental results show that grain size is strongly influenced by the casting speed. in addition, the distribution of grain sizes across the billet diameter is mostly determined by. Billet central region, is the necessary prerequisite to the floating grain research. the radius variations of grain size and das along the billet diameter are shown in fig. 3, (a) grain size and (b) das. grain size is shown to increase gradually with the increasing distance from the billet periphery. the mean value. Longitudinal section photographs (only deformation zone is outlined in dashed green line, angle θ for strain calculation is indicated with solid white line) of deformation zone in the ecap billets with different billet size, (a) 12 mm (b) 32 mm and (c) 50 mm (for interpretation of the references to colour in this figure legend, the reader is.

The folding, die underfilling, rib shifting and average grain size of primary equiaxed α were investigated using five different unequal thickness billets in transitional region of ti alloy multi rib component under isothermal local loading and compared with integral loading. in terms of the macro deformation, the results show that the material transfers from the second loading zone into the. Per zhang et al. [14], during dynamic recrystallization grain size is a function of temperature and strain rate, and schikorra et al. argued that this is a result of a critical strain value being.
