    A simple process, based on the mechanical aeration of a powder slurry, followed by gel casting and sintering, has been used to produce stainless steel metal foams. The foams have spherical pores, connected by windows, to create an interconnected, open cell structure. Despite the simplicity of the process, the foams have good and reproducible foam structures and compressive mechanical properties.

  2. Importance of Bimodal Structure Topology in the Control of Mechanical Properties of a Stainless Steel

    Creating bimodal grain size distribution in crystalline materials is an effective strategy to improve structural efficiency. Present investigation demonstrates that further control over topology through the formation of bimodal ‘harmonic’ structure simultaneously increases average values of strength and ductility, reduces the variation of corresponding properties, and thwarts the localization of plastic flow.

  3. Carbon-Dioxide Laser Beam Polishing of Fused Silica Surfaces – Process Development and Optimization

    Kerstin Hecht, Jens Bliedtner, Matthias Rost, Hartmut Müller and Thomas Schmidt

    Article first published online: 22 SEP 2014 | DOI: 10.1002/adem.201400363

    We present a process development and application for laser polishing of fused silica. Many parameters and environmental conditions influence the surface condition as well as the final quality. Thus, it is necessary to examine and optimize the finishing technique using different analyzing methods.

  4. Spark Plasma Sintering and Characterization of Graphene Platelet/Ceramic Composites

    Kyle Jiang, Jiran Li and Jian Liu

    Article first published online: 22 SEP 2014 | DOI: 10.1002/adem.201400326

    Alumina (Al2O3) and zirconia (ZrO2) toughened Al2O3 (ZTA) composites reinforced with GPLs were fabricated respectively using spark plasma sintering. The addition of GPLs hinders the growth of the ceramic matrix grains and help form homogenous microstructures of the ceramic matrices. Approximately, a 26.4 and a 29% improvements in fracture toughness were achieved for GPL/Al2O3 and GPL/ZTA composites, respectively.

    The functional behavior of MREs is briefly explained. The art of the materials provides the current position and mapping of the matrix and filler particles. Types of matrix and particles are mentioned together with the level of the research interest on MREs. Description of the fabrication is provided in simple diagrams as summarized from previous works to enhance the MREs performance. The possible tests to reveal the characteristics of the MREs are delivered with the global experimental setup. The review also explains the applications of MREs as well as discussion on the MREs future promising applications.
