Application of Mechanical Alloying in Synthesis of Intermetallics

Original language description

Mechanical alloying is an interesting method of direct synthesis of various kinds of compounds and preparation of solid solutions using pure elemental powders by high-energy milling. In this paper, the modified process of mechanical alloying, which was developed at UCT Prague, is applied for the synthesis of intermetallics. This process - ultra-high energy mechanical alloying - uses extremely high ball-to-powder ratio (50-70:1), thus enabling very high degree of deformation of the powders, as well as the friction. Due to these effects, the temperatures up to 700 degrees C can be probably achieved locally for a short period. It enables to initiate the same chemical reactions between metallic powders as in self-propagating high-temperature synthesis. This study compares the ultra-high energy mechanical alloying with self-propagating high-temperature synthesis in selected alloy systems (Fe-Al, Ni-Ti, Fe-Al-Si) in order to explain the formation of intermetallics in this innovative process.
