Application of Mechanical Alloying in Synthesis of Intermetallics

Popis výsledku v původním jazyce

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.
