| Özet |
| In recent years, mechanical alloying (MA) has recognized as an attractive solid state nano powder fabrication method, which explores the simple operations for mass production and low economical processing method. The actual process of MA starts with mixing of the powders in the right proportion and loading the powder mix into the mill along with the grinding medium. This mix is then milled for the desired time interval until a steady state is reached, when the composition of every powder particle is the same as the proportion of the elements in the starting powder mix. The milled powder is then consolidated into a bulk shape and heat treated to obtain the desired microstructure and properties. Thus, the important components of the MA process are the raw materials, the mill, and the process variables. In this paper fundamental aspect of MA and effected factors involved in the selection of raw materials, types of mills, and process variables are overviewed. Except of well known examples, the paper has also extended concerning with the performed researches on the production of MgB 2 by use of high-energy mechanical milling methods. In the synthesis of MgB 2, as bulk, wire or thin film form the structure of the precursor powders, is very critical to obtain good superconducting properties. Ductile deformation behavior at low temperatures and small grain size, which enhance the grain boundaries, are accepted as a favorable preconditions of achieving the high quality MgB 2.(author) |
