A New Model in Glass Forming Range of Binary Alloys

A. Yazdani and M.J. Hadianfard

Glassy metals have been prepared by various techniques such as rapid cooling of liquid or vapor phase, atom by atom deposition, particle bombardment and solid state reactions such as mechanical alloying. It is well known that glassy metal cannot be produced in every binary composition, thus determination of the range of composition in which the glass is produced, is very important. There are several models to predict the possibility and extent of amorphization in binary alloy systems. Most of them are designed based on microstructural properties such as Egami or Miracel model, thermodynamical phenomena such as enthalpy in Miedema or Bakker Model and statistical analysis of existing experimental data such as analyzing enthalpy vs. atomic radios ratio in Zhang model. In these models, the production process is not considered, while the experimental data shows that glass forming range is process dependent. In the present research, by considering the conditions of mechanical alloying process, a new microstructural model based in atomic arrangement changes during process was developed. Using this model the difference of glass forming range in the processes of mechanical alloying and rapid solidification of liquid was justifiable and the supposed model was more adaptive to mechanical alloying produced glasses than another models.
