Cryogenic Mechanical Alloying of Poly (ether ether ketone) - Polycarbonate Composite Powders for Selective Laser Sintering [PDF]

open access: yes, 1999
Mechanical alloying is a solid state processing technique traditionally used in the metallurgical industry to extend solubility limits in alloy systems. Mechanical alloying can also be used to blend polymer systems at ambient or cryogenic temperatures.

Alloying Mechanisms for Epitaxial Nanocrystals [PDF]

open access: yesPhysical Review Letters, 2007
The different mechanisms involved in the alloying of epitaxial nanocrystals are reported in this letter. Intermixing during growth, surface diffusion and intra-island diffusion were investigated by varying the growth conditions and annealing environments during chemical vapor deposition.

How the hammering process of cymbals affects their vibration characteristics

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Cymbals are percussion instruments that vibrate and radiate sounds when hit with a stick or when used in pairs. The sound radiated from a cymbal depends on its vibration characteristics.

Alloying effect on the ideal tensile strength of ferromagnetic and paramagnetic bcc iron [PDF]

open access: yes, 2016
Using \emph{ab initio} alloy theory formulated within the exact muffin-tin orbitals theory in combination with the coherent potential approximation, we investigate the ideal tensile strength (ITS) in the $[001]$ direction of bcc ferro-/ferrimagnetic (FFM)
