Static techniques are both less expensive and easier to use in experimental studies of the phase equilibria in a given system. Therefore, these are the most commonly used methods to prepare specimens and collect data. The synthetic method is often known, not necessarily disparagingly, as the "shakeandbake"
techniques. Results obtained by experiments under either argon or air atmosphere are analysed by Xray diffraction and Möss spectroscopy, together with microstructure observations. It is shown that ball milling products are strongly affected by the kind of atmosphere, while selfpropagating hightemperature ones are only weakly influenced.
