Inhomogeneous grain growth
WebbThe grain-growth behavior of the 100nm-thick 6N-Cu ・〕m is similar to that observed in the 100nm-thick 4N-Cu ・〕m, as shown in Fig. 1. However, the grain growth rate of the 6N-Cu ・〕m is slower than that of the Table 1 Impurity concentrations detected in Cu targets and sputter- deposited ・〕ms. Webb9 juni 2024 · As can be seen in figure 2, the grain size distribution is inhomogeneous, and there are small grains around larger grains, which is due to DRX. At the same time, the number of large grains at the edge and center of 250 °C is significantly more than 350 °C.

With the increase in grain size and decrease in Z parameter, the geometrically necessary dislocation density decreases, which shows the approximately power-law relationship.
WebbThe grain growth, which dominates the plastic deformation of the present sample, can be reasonably interpreted as a mechanically driven GB migration process, similar to previous obser- vations in NG metals (16–23). Webb29 maj 2024 · The common phenomena can be summarized as follows: with the decreasing grain size, both the contents of tetragonal and rhombohedral structures and TC (or Td) increase, while the dielectric and piezoelectric responses decrease. For this issue, several possible mechanisms have been proposed.
WebbGraphs show that the slope of the curve representing the bridging rise grows sharply with the value of the height of the bridging base exceeding 0.2 m. For a bridging base height of 0.34 m, it attains its maximum value, indicating inhomogeneous behavior of grain flow from the hopper outlet hole.
Webb18 dec. 2009 · The grain growth observed in this study is also characterized by a grain size distribution that broadens as grain size increases ( Fig. 4B ), as opposed to a pure shift in the distribution toward larger grain sizes as would be expected for normal thermally driven grain growth ( 28) or the grain growth observed in superplastic deformation ( … hotel sunroute goshogawara agodaWebb5 apr. 2024 · In the case of 0.58 T m, the total number of grains increases rapidly from approximately 100 ps after an incubation period.
