Thermoelectric properties of Co, Ir, and Os-Doped FeSi Alloys: Evidence for Strong Electron-Phonon Coupling

, 2011
The effects of various transition metal dopants on the electrical and thermal transport properties of Fe1-xMxSi alloys (M= Co, Ir, Os) are reported. The maximum thermoelectric figure of merit ZTmax is improved from 0.007 at 60 K for pure FeSi to ZT = 0 ...

Mechanical alloying in a planetary ball mill : kinematic description

Le Journal de Physique IV, 1994
Based on a kinematic modeling of the planetary ball mill, the kinematic equations giving the velocity and the acceleration of a ball in a planetary ball mill apparatus are given. The kinetic energy transferred at the collision event and the shock frequency are also calculated.

Preparation of strontium hexaferrite magnets from celestite and blue dust by mechanochemical route [PDF]

, 2008
In the present investigation celestite (natural ore of strontium) and blue dust (iron ore fines) have been used for the preparation of strontium hexaferrite powder. The mechanical alloying process has been adopted to prepare strontium hexaferrite powder.
