On structure and mechanical properties of ultrasonically cast Al–2% Al2O3 nanocomposite
TL;DR: In this paper, the structure of an ultrasonically cast nanocomposite of Al with 2 wt.% nano-sized AlO{sub 2 O{sub 3} (average size {approx}10 nm) dispersoids was investigated by nanoindentation and tensile tests.
Journal ArticleDOI
Structure and mechanical properties of Al–Ni–Ti amorphous powder consolidated by pressure-less, pressure-assisted and spark plasma sintering
TL;DR: In this paper, the authors have made use of spark plasma sintering (SPS) and hot-pressing and pressureless sinterring techniques to prepare highly dense bulk Al-based nanocomposite consisting of evenly distributed nano-intermetallic particles and amorphous phase.

Microstructure and mechanical properties of mechanically alloyed and spark plasma sintered amorphous–nanocrystalline Al65Cu20Ti15 intermetallic matrix composite reinforced with TiO2 nanoparticles
TL;DR: In this article, a multiphase Al65Cu20Ti15 intermetallic alloy matrix composite, dispersed with 10% of TiO2 nanoparticles, has been processed by mechanical alloying, followed by spark plasma sintering under pressure in the temperature range of 623-873 K. Transmission electron microscopy shows that the composite sintered at 873 K has partially amorphous microstructure, with dispersion of equilibrium, crystalline, intermetall precipitates of Al5CuTi2, Al3Ti, and Al2Cu of 25

Microstructural and nuclear magnetic resonance studies of solid-state amorphization in Al–Ti–Si composites prepared by mechanical alloying
TL;DR: In this article, high-energy planetary ball milling was used to yield a composite microstructure with varying proportions of amorphous and nanocrystalline intermetallic phases.
Journal ArticleDOI
Effect of sintering on microstructure and mechanical properties of nano-TiO2 dispersed Al65Cu20Ti15 amorphous/nanocrystalline matrix composite
TL;DR: In this paper, the phase and microstructural evolution at appropriate stages of mechanical alloying/blending and sintering was monitored by X-ray diffraction and scanning and transmission electron microscopy.
