Fabrication and investigation on the properties of ilmenite (FeTiO₃)-based Al composite by accumulative roll bonding

Abstract

In the present study, the aluminum (Al) 1050–FeTiO3 composite was fabricated through accumulative roll bonding process, and the resultant mechanical properties were evaluated at different deformation cycles at ambient temperature. The effect of the addition of FeTiO3 particle on the microstructural evolution and mechanical properties of the composite during accumulative roll bonding was investigated. The Al–2, 4, and 8 vol.% FeTiO3 composites were produced by accumulative roll bonding at room temperature. The results showed improvement in the dispersions of the particles with the increase in the number of the rolling cycles. In order to study the mechanical properties, tensile and hardness tests were applied. It was observed that hardness and tensile strength improve with increasing accumulative roll bonding cycles. The microhardness and tensile strength of the final composites are significantly improved as compared to those of original raw material Al 1050 and increase with increasing volume fraction of FeTiO3, reaching a maximum of ∼75 HV and ∼169 MPa for Al–8 vol.% FeTiO3 at seventh cycle, respectively.

Study of wear losses and frictional heat dissipation during dry sliding wear of ilmenite reinforced Al-alloy composite

“…Among these natural minerals, India is the 2nd largest country for ilmenite (FeTiO 3 ) mining (∼348MT per year). 18,19 Rasidhar et al 20 and Elwan et al . 19 reported that the addition of ilmenite into the aluminum alloy enhanced the mechanical properties.…”

“…Hence, the natural minerals viz. sillimanite, 10 ilmenite, 11 garnet, 12 zircon, 13 and rutile 14 are preferred over synthetic ceramics. Kumar et al 15 observed that the addition of 2–6 wt.…”

In these composites, the intermetallic phase FeAl 3 developed during casting and created the hindrance for the dislocation movement within matrix inducing higher load resistance of the composites.…”

Study of mechanical properties and wear resistance of nanostructured Al 1100/TiO2 nanocomposite processed by accumulative roll bonding

“…According to some reports, the increment of roughness increases the wear and corrosion rate of materials. [35][36][37] Characterization of nanocomposites is highly important in the implementation of nanocomposite studies for ensuring the successful manufacturing of these kinds of materials.…”

Effect of addition of SiC particles on the Microstructure and Hardness of Al-SiC composite

“…Powder metallurgy, stir casting method [3][4][5][6][7][8][9][10], accumulative roll bonding (ARB) method [11][12][13][14][15][16][17][18] were utilized to prepare the aluminum matrix with different reinforced composite. From the results, it is identified that the mechanical properties obtained from both methods exhibit the improved properties of the composites.…”
