TL;DR: The possibilities for manufacturing metal foams or other porous metallic structures are reviewed in this article, where various manufacturing processes are classified according to the state of matter in which the metal is processed, such as solid, liquid, gaseous or ionised.

TL;DR: In this paper, the authors present relationships between the durability, the governing material properties and salient morphological features of thermal barrier coatings and show that the failure is ultimately connected to the large residual compression in the thermally grown oxide through its roles in amplifying imperfections near the interface.

TL;DR: In this paper, the authors compared the performance of stochastic (foamed) cellular metals with the projected capabilities of materials with periodic cells, configured as cores of panels, tubes and shells.

TL;DR: The measurement of contraction of collagen-based scaffolds by fibroblasts in vitro using a cell force monitor is described, which shows typical microstructures of many porous scaffolds ressemble that of an engineering foam.

TL;DR: In this paper, the basic scaling relations are identified and used to gain some understanding of the relative importance of the various mechanisms that arise for application scenarios with minimal thermal cycling, based on stresses that develop because of TGO growth strains in combination with thermal expansion misfit.

TL;DR: In this article, a multiscale modeling method for analyzing the growth of vapor deposited thin films and nanoparticles has begun to emerge and is reviewed and is used to identify new growth processes that utilize adatom energy control, low energy ion assistance, or highly mobile, low solubility chemical species (surfactants) to control surface diffusion controlled film growth.

TL;DR: In this article, a systematic method is developed to select the most appropriate sensor for a particular application, based on a wide range of candidate sensors exist, and many are based on coupled electrical and mechanical phenomena such as the piezoelectric, magnetostrictive and pyroelectric effects.

TL;DR: In this article, the authors focus on two modern aspects of fundamental and practical interest: the mechanism of dispersion hardening at high temperatures, which allows the design of alloys operating close to their melting point; and the constraints on dislocation and diffusional deformation processes in metallic thin films, a potential reliability problem for micro-systems subjected to high internal stresses.

TL;DR: In this paper, the current status of modelling the compaction and sintering of particulate materials is reviewed, and deficiencies in the current models are described and areas where additional modelling is required are identified.

TL;DR: In this article, the importance of a pre-defined questionnaire approach in process selection is illustrated for casting, joining and surface treatments, and possible new developments toward a better integration of materials and process selection in the whole design procedure are proposed.

TL;DR: In this paper, the authors restrict themselves to phenomena for which a continuum approach is adequate and discuss the simultaneous effects of damage and particle clustering on the elasto-plastic response of metal matrix composites.

TL;DR: In this paper, the authors consider the problem of finding a suitable manufacturing process by considering the complex coupling between characteristics of the design, the material and the process, and propose a methodology for task-based process selection, which involves considering the attributes of the material, design and process which are relevant to the task in hand.

TL;DR: A long history of collaboration between earth and materials scientists in modeling the relevant micromechanics and formulating appropriate constitutive relations can be found in this paper, where the authors present a model of the deformation processes in the Earth's interior.
