“…The elastic constants, primarily the compliances, of bulk silver have been measured by several sources [30][31][32][33][34][35] -the most recent by Wolfenden et al 35 Using the expressions for calculating the Young's modulus, E, outlined in Nye 36 , Wolfenden's measurements can be presented in terms of directional Young's moduli as shown in Table II. This table illustrates that in bulk silver, the directionally-dependent Young's modulus, E, is greater in the <111> than in the <200> and <220> directions (E<111> > E<110> > E<100>). If the silver nanoparticles behaved like the bulk material, this would mean that the nanoparticles would more likely compress in the {200} direction than the {111} direction.…”

We present experimental evidence that silver nanoparticles in the size range of 5 -10 nm undergo a reversible structural transformation under hydrostatic pressures up to 10 GPa. We have used xray diffraction with a synchrotron light source to investigate pressure-dependent and size-dependent trends in the crystal structure of silver nanoparticles in a hydrostatic medium compressed in a diamond-anvil cell. Results suggest a reversible linear pressure-dependent rhombohedral distortion which has not been previously observed in bulk silver. We propose a mechanism for this transition that considers the bond-length distribution in idealized multiply twinned icosahedral particles. To further support this hypothesis, we also show that similar measurements of single-crystal platinum nanoparticles reveal no such distortions.

“…In the early days of material and metallurgical science, the lattice constant [1] and elastic constant [2] have been measured and investigated thoroughly for silver primary solid solution, namely, silver solid solution of cadmium, indium, tin, antimony, etc. Solid solution strengthening mechanism is well-known, responsible for increasing the yield strength and hardness of metal which is the result of the interactions between dislocations and solute atoms by following mechanisms: elastic interaction, modulus interaction, stacking-fault interaction, electrical interaction, short-range order and long-range order interaction [3].…”

The growth and stress vs. strain characterization of the silver solid solution phase with indium Silver solid solution phase with indium has been discovered to have great mechanical properties and anti-tarnishing property, as shown in the results of our previous study. It is important to know the stress vs. strain curve before adopting this material in industrial applications. The growth of the homogeneous silver solid solution phase with indium is first described. The X-ray diffraction (XRD) patterns and scanning electron microscope/energy dispersive X-ray spectroscopy (SEM/EDX) results are reported to verify the chemical composition of silver solid solution phase with indium samples. Based on the results, one could reversely determine the indium element composition in (Ag)exxIn solid solution by examining the lattice constant value using XRD for unknown compositions. The preparation of ASTM tensile test samples and tensile test experimental setting are explained in details. The intrinsic mechanical material properties of silver solid solution phase with indium, i.e., characteristic stress vs. strain curves, are presented and analyzed, with pure silver stress vs. strain curve in comparison. According to the experimental results, silver solid solution phase with indium exhibits low yield strength, high ultimate tensile strength, and large elongation value before fracture, compared to pure silver. In addition, fractography of the fracture surface of the tested sample has been studied to confirm the superior ductility of silver solid solution phase with indium. These superior mechanical properties may bring silver solid solution phase with indium new applications in various industries such as electronics and brazing.

The texture and microstructure of thin silver films in Ag/Ti bilayer structures have been characterized as a function of vacuum annealing temperature and time with the use of x-ray diffraction and transmission electron microscopy. A strong preexisting ͑111͒ texture in Ag films was further improved upon annealing as evidenced by an increased intensity and narrower distribution of the texture along the film normal. A new ͑200͒ texture component was generated after 600°C annealing; it however had a relatively low intensity when compared to the dominant ͑111͒ texture. No abnormal grain growth was observed in annealed Ag films. The texture evolution in all films appeared to complete within the first 15 min annealing, while the microstructure continued to change with additional annealing time. The roles of both surface energy and strain energy in the grain growth were evaluated. A model of the grain growth and texture evolution has been proposed to explain these observations.
