    In recent years, high entropy alloys (HEAs) receive wide attention due to its unique alloy design concept and outstanding properties. This review presents a general overview of HEAs as a potential candidate for high-temperature applications. The need for the profound research on the high-temperature properties of HEAs is highlighted.

    The initiation curves of the fatigue delamination process of a composite materials with an MTM45-1 epoxy matrix and unidirectional IM7 carbon-fiber reinforcements have been obtained for two mode mixities and for a tensile ratio. Crack growth rate behavior differs from one degree of mode mixity to the other, being the cause the varying of mode I loading on the delamination process.

    Reactive structural materials serve both as structural elements and a source of chemical energy released upon initiation. Chemical composition, scale at which reactive components are mixed, and the structure of materials are controlled by the method of preparation and compaction of the composites. Material types, their synthesis and methods of characterization of their mechanical and energetic properties are reviewed.

    Polymethylmethacrylate (PMMA) is an important industrial material for microfluidics owing mainly to its optical transparency, biocompatibility, and low cost. We present “Liquid PMMA,” a fast curing PMMA prepolymer which can be used as a negative photoresist and directly structured by light. PMMA microchips can be structured within minutes.

  5. Using Post-Deformation Annealing to Optimize the Properties of a ZK60 Magnesium Alloy Processed by High-Pressure Torsion

    The production of ultrafine grained structure through the severe plastic deformation processes is of increasing interests in lightweight materials. Magnesium alloys show poor ductility at room temperature after severe plastic deformation. The results of this study suggest that a post-HPT annealing for a short period of time can be effective in achieving a reasonable combination of strength and ductility.
