Evidence for a Peierls phase-transition in a three-dimensional multiple charge-density waves solid

, 2012
The effect of dimensionality on materials properties has become strikingly evident with the recent discovery of graphene. Charge ordering phenomena can be induced in one dimension by periodic distortions of a material's crystal structure, termed Peierls ...

Producing Ni-base superalloys single crystal by selective electron beam melting [PDF]

Scripta Materialia, 2018
Abstract The possibility to produce Ni-base superalloy single crystals by selective electron beam melting (S-EBM) is demonstrated. The production of single crystals specimens was achieved by a tight control of the processing conditions without requiring a grain selector or a crystal seed.

Nitride‐Reinforced Metal Matrix Nanocomposite Powders Production by Plasma‐Assisted Thermochemical Treatment of Intermetallic Powders

Advanced Engineering Materials, EarlyView.
This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...
