The mechanical alloying was performed in a conventional planetary ball mill (Fritsch "Pulverisette 5"). The ball milling intensities used are 3, 5 and 7. The authors [19] show that for ball milling intensity 5 a pure amorphous phase is formed from about 30 to 83 at.% Ni. The ball milling duration required to achieve the amorphization process was 60 h. For ball milling intensity 7, for the same ...

Because of the fine microstructures, mechanical properties in the longitudinal and transverse directions are more isotropic than those found with conventionally fabricated wrought sections (Section 2.5) which is a significant advantage. Both alloys also show exceptional resistance to general corrosion ...

Planetary ball mill is a very often used machine for mechanical alloying, especially in Europe. Because very small amount of powder (for example, as little as a few grammes), is required, the machine is suitable for research purposes in the laboratory. A typical planetary ball mill consists of one turn disc (sometimes called turn table) and two or four bowls. The turn disc rotates in one ...

The background temperature of milling bodies and processed material is analyzed using calorimetric measures and methods of melting of reference substances during mechanical alloying of powders in planetary ball mill. It is shown that estimation of the background temperature using the calorimetric method provides more precise measurements compared to the melting method of reference substances.

A simple calorimetric technique was used to estimate the temperature of balls during mechanical alloying (MA) in an AGO-2 planetary ball mill. Temperatures up to 600 °C were realized for balls in the case that compact layers of milled powder are formed on the surface of the balls and the wall of the vial. Though free powders in the vial would decrease the temperature of the balls, it was ...

time of milling in the planetary mills of 28 and 50 g accelerations is much lower than that in the milling devices of lower energy density. During the process of mechanical alloying in the planetary mill further reduction of the crystallite size took place, yielding nanoscale crystallite size for all components.
