| Abstract | ||||
| The modification and reduction of particle size of rapidly solidified shots of Fe-3Al-5Si during ball milling is investigated. The reduction of the microstructure is monitored by differential scanning calorimetry and transmission electron microscopy. Optical and scanning electron microscopes have been used to investigate the metallographical and morphological changes of the ball-milled alloy powders at the several stages of milling . The results have shown that the end-product of Fe-3Al-5Soi alloy milled for 21 hrs consists of uniform fine (1 μm in diameter) powder particles with spherical-like shape it is also shown that ball milling technique reduces the particle size of the alloy powder to a nanometer scale (about 5 nm) after 21 h of milling. The differential scanning calorimetry has shown several exothermic peaks, which could be attributed to the recovery and the recrystallization of the severely deformed alloy powders. | ||||
