    The limiting rotation speeds (LRS) of SiCf/Ti–6Al–4V composite rings are predicted by finite element simulations in consideration with different influencing factors, including reinforced area, fiber volume fraction, diameter, and working temperature. The results show that the LRS increases with the increase of reinforced area and fiber volume fraction, and decreases with the increase of diameter and working temperature. The maximum stress locates in the bonding zone between composite core and matrix cladding near the internal diameter.

    One-stage preparation of superhydrophobic stainless steel surface has been achieved by combining chemical etching and assembly. The contact angle of the prepared surface reaches as high as 175°, which is caused by the formation of the “honeycomb” 3D network structure. Electrochemical corrosion test shows that the prepared superhydrophobic surface possesses 16 times higher corrosion resistance than common stainless steel surface.

  3. Preparation of Mg/Nano-HA Composites by Spark Plasma Sintering Method and Evaluation of Different Milling Time Effects on Their Microhardness, Corrosion Resistance, and Biocompatibility

    Mg/nano-HA composites are prepared by Spark Plasma Sintering (SPS) method. This study finds that an appropriate time (5 h) during high energy ball milling process effectively can eliminate the prior particle boundary (PPB). And also it is a good choice for the preparation of Mg-based composites with desirable microhardness, stable corrosion resistant, and excellent biocompatibility.

  4. Iron and Nickel Cellular Structures by Sintering of 3D-Printed Oxide or Metallic Particle Inks

    Shannon L. Taylor, Adam E. Jakus, Ramille N. Shah and David C. Dunand

    Version of Record online: 16 SEP 2016 | DOI: 10.1002/adem.201600365

    Inks comprised of Fe, Fe2O3, Ni, or NiO powders, an elastomeric binder, and graded volatility solvents are 3D-printed via syringe extrusion and sintered in hydrogen to form metallic cellular structures with overall relative densities of 32–49%. This work presents a comparison of the microstructures and compressive properties of the metallic structures derived from either metallic- or oxide-based inks.

  5. A Phenomenological Model of Twinning Kinetics

    The authors present a model of deformation twinning based on the idea that twin generation is a stress-driven process. The model is validated by means of in situ video observation and the acoustic emission technique during deformation Mg alloys.
