Abstract
Abstract Three-dimensional finite element simulations of nano-porous silver structures are performed to understand the correlation between the porous morphology and the mechanical behavior. The nanostructures have been obtained from ptychographic X-ray computed tomography. The simulations allow distinguishing between the interplay and role of the ligament size, the pore morphology and the porosity, and therefore provide a better comprehension of the experimental observations. We show that the proposed model has a predictive character for mechanical behavior of nano-porous silver.

Abstract This work reports on the microstructure and mechanical properties of porous silver films produced with different sintering parameters. The microstructure is investigated by high-resolution ptychographic X-ray computed tomography and scanning electron microscopy. The mechanical properties are obtained from constant strain rate tensile tests. It is found that for this class of samples both grain size and ligament diameter have little effect on the magnitude of the yield stress. Instead, a...

In microelectronics applications, SnAgCu lead-free solder joints play the important role of ensuring both the mechanical and electrical integrity of the components. In such applications, the SnAgCu joints are subjected to elevated homologous temperatures for an extended period of time causing significant microstructural changes and leading to reliability issues. In this study, the link between the change in microstructures and deformation behavior of SnAgCu solder during ageing is explained by d...

High-pressure die-casting (HPDC) AZ91 tensile specimens were used to investigate characteristics of gas pores and their effects on mechanical properties of HPDC AZ91 magnesium (Mg) alloy. Combining the stereoscopic morphology of gas pores obtained from a three-dimensional (3D) reconstruction technique with the experimental data from uniaxial tensile testing, we worked on finite element simulation to find the relationship between gas pores and the mechanical properties of HPDC AZ91 Mg alloy. Resu...

High resolution serial block-face scanning electron microscopy has been performed on sintered micro-silver pastes that are used as lead replacement joints for die bonding. The size and spatial distributions of the porosity before and after ageing were determined by quantification of the segmented 3D images. The elastic modulus was determined by an image-based finite element model and validated by results obtained from a dynamical resonance method. In agreement with contemporary analytical models...

The microstructure of porous silver layers produced under different low temperature pressure-assisted sintering conditions is characterized and linked with the mechanical behavior studied insitu during X-ray diffraction. Peak profile analysis reveals important strain recovery and hardening mechanism during cyclic deformation. The competition between both mechanisms is discussed in terms of porosity and grain size.

Abstract Mechanical properties of porous SOFC electrodes are largely determined by their microstructures. Measurements of the elastic properties and microstructural parameters can be achieved by modelling of the digitally reconstructed 3D volumes based on the real electrode microstructures. However, the reliability of such measurements is greatly dependent on the processing of raw images acquired for reconstruction. In this work, the actual microstructures of La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) cath...

The Materials Science beamline at the Swiss Light Source has been operational since 2001. In late 2010, the original wiggler source was replaced with a novel insertion device, which allows unprecedented access to high photon energies from an undulator installed in a medium-energy storage ring. In order to best exploit the increased brilliance of this new source, the entire front-end and optics had to be redesigned. In this work, the upgrade of the beamline is described in detail. The tone is did...

The Weaire–Phelan (WP) structure is the lowest energy structure known of an ideal monodisperse foam in the dry limit. To date, it has not been realized in the laboratory. Instead Lord Kelvin's 1887 structure, which it supplanted in 1994, has repeatedly been found in attempts to produce an ordered structure. This paradox is attributable to the flat walls of the containers used, with which the Kelvin structure is more compatible. Accordingly, we have fabricated a patterned mould whose faceted wall...

With the progress of miniaturization, in many modern applications the characteristic dimensions of the physical volume occupied by particle-reinforced composites are getting comparable with the reinforcement size and many of those composite materials undergo plastic deformations. In both experimental and modelling contexts, it is therefore very important to know whether, and up to which characteristic size, the description of the composites in terms of effective, homogenized properties is suffic...

Abstract In-situ Al–Mg2Si composites (0, 5, 10, 15, 20 wt% Mg2Si) were synthesized in an Al–Mg–Si system through gravity casting route. Influences of the Mg2Si addition (in terms of Mg and Si) on the mechanical properties, microstructural morphology, fracture behaviors, micro-mechanical response and failure initiation were systematically studied through experiments and mathematical modeling. Experimental results show that the primary Mg2Si formed in Al-10 wt% Mg2Si composite and the volume perce...

Abstract Sintered silver is a very promising die-attach material which is hopeful to be adopted in the third generation of power electronics. Thermal conductivity is an important index to characterize the heat conduction capacity of sintered silver. In this paper, a numerical model to compute equivalent thermal conductivity of sintered silver is proposed and verified based on the method with microstructure characteristics modelling. Based on the computations, the variations of the equivalent the...

Abstract Alumina hexagonal microplatelets, have been widely utilized to fabricate biomimetic materials. Due to their complex microstructure, accurately predicting the response of biomimetic materials using analytical or numerical approaches can be difficult. More specifically, for computational finite element assessment, the main challenge is regarding the generation of realistic non-uniformly dispersed 3D representative volume element (RVE) geometries. Hence, a novel rapid approach named stagge...

Abstract During the last years more and more investigations on the viscoplastic behavior of sintered silver inter-connections were published. To classify the meaning of the rate-dependency of porous silver films a good model description is necessary. Since different formulations are available and already used, this work focusses on different continuum mechanics modeling strategies for describing the experimental results. Creep tests at different load and temperature levels as well as monotonic h...
