Normalized channeling yield curves of bulk InAsBi on GaSb for <100> and <110> channeling. Its influence on wear has been well recognized in earlier literature. For Corrosion rates were accelerated 10–100-fold when their concentrations were increased [51]. 12.3, the junction depth, χj determined at a background concentration of 1 × 1018 cm–3, for the sample after laser annealing at 0.52 J/cm2 is ~ 300 Å and is shallower than that of a reference samples using spike anneal by at least 280 Å. (1979) and Tsu et al. Mayer et al., 1970) gave clear indications of the possibility of forming super-saturated solid solutions via solid-phase recrystallization. Such results (Williams and Short, 1982) have suggested that the equilibrium substitutional solubility limit for Sb in Si in the temperature range 750-850°C is close to 2.2 × 1020 cm−3, about a factor of three above the maximum equilibrium solubility reported by Trumbore (1960). In this state the alloy becomes softer, and it is then said to be in the over-aged condition (see Figure 8.2). This quantity is The microstructural investigations and microanalysis of a series of Ba6–3x Ln8+2xTi18O54 (Ln = Nd, Gd) revealed that the solid solubility limit of Bi substitution of Ln depends on the composition of the Ba6–3xLn8+2xTi18O54 phase. Variation of τf as a function of Bi 3+ content in Ba6–3x(La1–y–z SmyBiz)8+2x Ti18O54. The rapid cooling suppresses the separation of the θ-phase so that the alloy exists at the low temperature in an unstable supersaturated state. Theoretical calculations indicate that displacement of Si crystal atoms by 0.1 Å into the <110> channel results in a 0.2 decrease in normalized yield curve width (Zhu et al., 2006). The maximum substitutional solubility concentrations which can be achieved in these dilute Si alloys by rapid quenching are limited by three mechanisms; lattice strain; instabilities created at the liquid-solid interface, which leads to segregation of the dopants; and fundamental thermodynamic considerations. C. Subramanian, in Surface Engineering of Light Alloys, 2010. The above results strongly indicate that due to the near-zero thermal budget of the laser thermal process, single-pulsed laser irradiation can produce abrupt, highly activated and ultrashallow p+/n junctions for CMOS technologies. Wersing [131] found that the addition of Bi2O3 in BaO–Nd2O3–5TiO2 decrease τf remarkably with an increase in ɛr and a decrease in Qf. Li has a high solid-solubility limit to Mg_2X to provide Mg_2X having high electric conductivity. This precipitation occurs by a nucleation and growth process, fluctuations in solute concentration providing small clusters of atoms in the lattice which act as nuclei for the precipitate. The τf of La-and Nd-based ceramics decreased up to y = 0.15 and then continuously increased. 14 can be understood on the basis of redistribution by diffusion in the liquid, provided k' is treated as a fitting parameter (White et al., 1980, 1982). 3.17. The peak-aged alloys have been shown to offer the best wear resistance among this group of alloys (Subramanian,1985). The total concentration of Bi incorporated into the lattice is ∼500 times the maximum equilibrium solid solubility limit. The validity of this Md method has been confirmed through a series of examinations of more than 30 ternary phase diagrams [13–16]. Addition of small amount of Mn and WO3 further improved Qf to about 7000 GHz. The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and presence of other chemicals (including changes to the pH ) of the solution. As discussed earlier, many alloying elements are useful in forming solid solution with aluminium, but their influence is limited to their solid solubility limits. From the XRD patterns of LA–Ni–Cu (Fig. The critical tolerance level [56] for commercial alloys were defined and applied to the production specifications for AZ91 and AM60. The backscattered ion yield increases as the sample is tilted away from the aligned orientation, and the angular deviation from zero is indicated for each curve. Therefore, this method is contrary to the classical approach by Hume-Rothery and Darken-Gurry [4,5], and inevitably the prediction along this Nv method is poor. In this case, the high resolution channeling spectra of Fig. Further addition of Bi caused the formation of Bi-rich phase, accompanied with considerable reduction of Qf value and increase of τf. This increased Qf to about 5800 GHz with ɛr = 88 and τf τ 0 ppm/°C.
