Dissolution mechanism of solid nickel in liquid zinc saturated with Fe KONG Gang(孔 纲), LU Jin-tang(卢锦堂), XU Qiao-yu(许乔瑜) School of Materials Science and Engineering, South China University... by diffusion of nickel atom across a concentration boundary layer in liquid Zn saturated with Fe, and is different from a mixed control mechanism of nickel in liquid pure zinc. The participation of Γ2......
GmbH Germany, part of Springer Nature 2021 Abstract: To study the influence of B4C particle size on the microstructure and damping capacities of (B4C+Ti)/Mg composites, in situ reactive infiltration... capacities of the composites prepared with 5 mm B4C are inferior to those of coarser particles. The dominant damping mechanism for the strain-damping capacity is dislocation damping and plastic zone......
