Synthesis and characterization of high volume fraction Al–Al2O3 nanocomposite powders by high-energy milling

Nanoindentation Study of Al356-Al2O3 Nanocomposite Prepared by Ball Milling

“…A survey of the previous studies indicates that a homogenous dispersion of fine particles in a fine grained matrix is beneficial to the mechanical properties of MMCs [5][6][7][8][9][10]. The use of Al-Al 2 O 3 has been limited due to high processing cost [11].…”

Advance on Al2O3Particulates Reinforced Aluminum Metal Matrix Composites (Al-MMCs) Manufactured by the Power Metallurgy(PM) Methods- Improved PM Techniques

“…Prabhu et al [21] have successfully prepared a Al-Al 2 O 3 powders with uniform distribution of the Al 2 O 3 reinforcement by HEBM techniques, in which the volume content is as high as 50% and particle size is as small as 50 nm. This was, for the first time, reported a uniform distribution of such ultra-fine particles of 50 vol% Al 2 O 3 in an aluminum matrix.…”

Characterization of Al Matrix SiC Reinforced Sub-Micron Composites Produced by Mechanical Alloying

“…Because of this reason a lot of studies were conducted combining advantages of Almatrix composites and MA process [4][5][6][7][8][9][10][11][12][13][14][15].…”

“…By performing XRD analyzes and mechanical tests (micro hardness and compression tests) were performed to the final structures as a result it can be said that MG operation has an increasing effect on micro hardness and compressive proof stresses of the powders. Braphu ve Suryanarayana [5], studied on synthesis and characterization of AlAl 2 O 3 composites in order to observe effect of particle size and weight ratio of the reinforcing powder in Al-matrix composites. They used Al 2 O 3 having particle sizes of 50 nm and 5 µm with changing weight ratios of 5-50%.…”
