Elastic properties of a tungsten-silver composite above and below the melting point of silver

Thermal Diffusivity Measurement for p-Si and Ag/p-Si by Photoacoustic Technique

“…The melting point of pure silver is 961°C [19]. The result show the melting point of the silver is within the range from 960 to 1200°C (two-layer sample) [20]. The decrease of silver thickness means the silver atoms distributed through diffusion inside of the bulk of the silicon as well as evaporation of silver atoms into atmosphere.…”

Reconstruction of three-dimensional anisotropic microstructures from two-dimensional micrographs imaged on orthogonal planes

“…The data was used within a finite-element simulation to compute the elastic modulus of the reconstructed microstructure using the method described in [17]. The computed properties of the reconstructed 3D microstructure closely follow the experimentally measured Young's modulus from [13] as shown in Figure 8b with an average error from the experimental data of about 5%.…”

“…Short-range correlations carry the greatest weightage in determining mechanical properties such as elastic modulus (e.g., [4]), although long-range correlations have been found to be important for phenomena such as surface roughening during plastic deformation [16]. To test if the elastic properties are well captured in the reconstructed 3D microstructure, we compared against the experimental data from [13] of the elastic modulus as a function of temperature. The elastic properties of the individual components at different temperatures are available from [14] and are listed in Table 1.…”

“…The experimental data in [13] provides a high-resolution planar microstructure image (Figure 7a) of a silver-tungsten composite with porous tungsten matrix and molten silver (volume fraction of silver phase p = 20%). The microstructure has been employed for several reconstruction studies [14,15].…”

A seamless approach towards stochastic modeling: Sparse grid collocation and data driven input models

“…The image (204 m × 236 m), shown in Fig. 19, is of a tungstan-silver composite [64]. This composite was produced by infiltrating a porous tungsten solid with molten silver.…”
