  1. Dynamic Recrystallization of Wrought–Solidified–Wrought Complex Structure in Ni-Based Superalloys

    Yongquan Ning, Bingchao Xie, Hui Li and Ming Wang Fu

    Article first published online: 29 AUG 2014 | DOI: 10.1002/adem.201400223

    Electron beam welding is conducted, and wrought–solidified–wrought complex structure is machined from the central part of the weldments. Dislocations drive the occurrence of DRX. Solidified dendrite can be greatly eliminated and refined after hot deformation due to repeating occurrence of DRX.

  2. X-Ray Photoelectron Spectroscopy Investigations of the Surface Reaction Layer and its Effects on the Transformation Properties of Nanoscale Ti51Ni38Cu11 Shape Memory Thin Films

    Dennis König, Dennis Naujoks, Teresa de los Arcos, Simon Grosse-Kreul and Alfred Ludwig

    Article first published online: 28 AUG 2014 | DOI: 10.1002/adem.201400317

    Ti51Ni38Cu11 thin films of different film thickness are investigated regarding the influence of the reaction layers on the chemical composition of the transforming phase and the corresponding functional properties. A model is proposed describing the different reaction layers on the surface of the thin film and at the substrate/thin film interface.

  3. Electrospray Deposition of Energetic Polymer Nanocomposites with High Mass Particle Loadings: A Prelude to 3D Printing of Rocket Motors

    Chuan Huang, Guoqiang Jian, Jeffery B. DeLisio, Haiyang Wang and Michael R. Zachariah

    Article first published online: 28 AUG 2014 | DOI: 10.1002/adem.201400151

    Nanocomposite energetic films (nanoAl/PVDF) were fabricated by an electrospray deposition process, which enables high mass loadings of nanoparticles to be incorporated within a polymer matrix. These free-standing films show good mechanical integrity, and self-sustaining reaction propagation. This approach enables the direct writing of metallized energetic material, bypassing traditional casting.

  4. Microstructures and Properties of Graphene-Cu/Al Composite Prepared by a Novel Process Through Clad Forming and Improving Wettability with Copper

    Zhan Yong Zhao, Ren Guo Guan, Xi Hua Guan, Zhen Xian Feng, Hui Chen and Yu Chen

    Article first published online: 21 AUG 2014 | DOI: 10.1002/adem.201400173

    An improved method is adopted to prepare graphene-Cu as an enhancement phase. A graphene-Cu reinforced pure aluminum composite is prepared by clad rolling. The graphene-Cu are distributed homogeneously in the composite. Mechanical properties of the graphene-Cu/Al composite are higher than that of the aluminum matrix.

  5. Preparation and Thermal Conductivity of Spark Plasma Sintered Aluminum Matrix Composites Reinforced with Titanium-Coated Graphite Fibers

    The figure shows the effect of fiber volume fraction on thermal conductivity (TC) of uncoated and Ti-coated graphite fiber (Grf)/Al composites. All the Ti-coated composites possess higher TC than pure Al and uncoated ones. Particularly, the TC of 50 vol% Ti-coated composite is increased to 238 W m−1 K−1, nearly 16% higher than that of pure Al and twice as high as that of the uncoated one.
