    Additive manufacturing has become a promising alternative for the fabrication of advanced multi-component alloys such as bulk metallic glasses (BMGs) and high entropy alloys (HEAs). Due to the intrinsic layer-wise fabrication process of additive manufacturing, more complex and large scale BMGs and HEAs components with controllable local microstructure and properties can be achieved.

    The effects of extrusion temperatures are investigated on the microstructures and mechanical properties of RS/PM Mg–7.5Al–0.8Zn alloys. The mechanical properties of RS/PM alloys are remarkably improved by reducing extrusion temperatures from 340 to 170 °C.

    The ionic liquids (ILs) stored in the pores of the copper matrix respond to the frictional, electrical, and electro-frictional coupling stimulation has been investigated using ball-on-disk friction tests under external electric fields. A proper voltage may accelerate the release of the ILs to the friction interface, thereby resulting in a low coefficient of friction.

    The authors investigate spin filtering mechanism by incorporating 2D materials in spin valve devices. Comparing to graphene, hBN device reveals pronounced spintronic features suggesting better spin filtering at the interfaces. Furthermore, graphene and hBN incorporated magnetic junctions reveal positive MR, while that for Gr-hBN heterostructure the signal not only becomes negative, but also facilitates efficient spin filtering at the interfaces.

  5. Enhanced Mechanical Properties of Multilayered Cu with Modulated Grain Size Distribution

    A bulk multilayered Cu with the alternating growth of nano-grained layer and ultrafine grained layer with the thickness ratio of about 10:1 is synthesized by electrodeposition technique. The multilayered Cu exhibits a better combination of high ductility and high strength in comparison with the corresponding monolithic nano-grained and ultrafine-grianed Cu.
