[ 1 ] - MICROSTRUCTURE STUDY ON AL-5%SiC NANOCOMPOSITE POWDERS
Abstract: In this study Al-5 (Vol) % SiCp nanocomposite powder has been successfully synthesized by high-energy planetary milling of Al and SiC powders for a period of 25 h at a ball-to-powder ratio of 15:1. The changes of the lattice strain, the crystallite size of the matrix phase, and the nanocomposite powder microstructure with time have been investigated by X-ray diffraction (XRD), X-ray m...
[ 2 ] - KINETICS OF -Fe NANOCRYSTALLIZATION IN Fe55Cr18Mo7B16C4 BULK AMORPHOUS ALLOY
Abstract: In this research work, crystallization kinetics of Fe55Cr18Mo7B16C4 alloy was evaluated by X-ray diffraction, TEM observations and differential scanning calorimetric tests. In practice, crystallization and growth mechanisms were investigated using DSC tests in four different heating rates. Results showed that a two -step crystallization process occurred in the alloy in which - Fe phas...
