“…This point is addressed in the subsection VB. Figures 14(a) and (b) visualize the deformation mode and the damage distribution at the interfaces obtained by the simulation of the bending test assuming T n0 ¼ T s0 ¼ 0:63GPa and G c ¼ 50J=m 2 : Figure 14(a) refers to the softening phase (load reduction) caused by cracking at about 1 lm overall deflection of the sample before unloading, while Figure 14(b) corresponds to approx. 2 lm overall deflection.…”

“…A logical consequence of this relationship is the steadily growing interest in investigating events on the micron scale by means of micromechanical experiments. For the past decade, we have been witnessing an intensive activity in micromechanical material testing such as compression of micropillars [1,2] or bending of microcantilevers. [3,4] Micromechanical testing can be a challenging task due to several reasons including machining of miniaturized specimens, various size effects, or precise and repeatable load application.…”

This work presents a combined experimental and computational study of the deformation and fracture of microcantilever specimens made of chromium(rhenium)-alumina metal-matrix composite (MMC), with a particular focus on the failure properties of the metal-ceramic interfaces. The obtained experimental results show that the bending strength of microcantilevers containing alumina particles in critical cross-sections near specimen's fixed end is considerably higher than that of unreinforced chromium(rhenium) samples. Brittle cracking along chromium-alumina interfaces is the dominant fracture mode of the composite microcantilevers. The interface characteristics are determined in an indirect way by numerical simulations of the experiment with account of the actual specimen microstructure from the scanning electron microscope (SEM) images. A parametric study demonstrates that the overall material response may be reproduced by different sets of model parameters, whereas the actual failure mode permits to discriminate among the possible alternatives. Using this approach, the in situ values of the chromium-alumina interface cohesive strength and the fracture energy are estimated.

Metal matrix nanocomposites (MMNCs) are an emerging class of metals with nanosized reinforcements and have been investigated extensively in recent decades due to their promising properties for widespread applications such as aerospace, automotive, biomedical, and electronics. In this article, a comprehensive review is presented on the science and engineering aspects of MMNCs, especially the processing, microstructures, and properties of MMNCs. Common processing and manufacturing approaches and post‐processing of MMNCs are discussed. Recent advances in the unusual mechanical, physical, and chemical properties of MMNCs are reviewed. Furthermore, the latest progress on the fundamental study of interactions between nanoparticles and metals, including dispersion, pushing, and engulfment during solidification, nucleation, and phase control, is presented. It is worth noting that the exciting opportunities of nanotechnology‐enabled metallurgy (nanotech metallurgy), which have grown out of the domain of MMNCs recently, are also presented briefly.
