| Description | Journal: Iop Conference Series: Materials Science and Engineering Nano-oxide dispersed aluminum alloys are widely used as structural components in different fields in aerospace, defence, transport and automobile industries. It is observed that the hardness of these Aluminium alloys (65-100 HV) could be significantly enhanced by uniform dispersion of nanometric $Y_{2}O_{3}$ and $TiO_{2}$ in high-Al matrix in presence of other alloying elements like Fe and Ti. In the present work, synthesis of Al (70%), 22 Fe (22 %), Ti (8 %), Al (69 %), Fe (22 %), Ti (8 %) with 1% nano-Y2O3 and Al (69%), Fe (22%), Ti(8%) with 1% $nano-TiO_{2}$ dispersed particles through mechanical alloying has been carried out. These alloys have been named as alloy A, B & C respectively on the basis of their weight percentages Subsequent consolidation of this alloy has been carried out through conventional sintering at 1000°C for 1 hour. X-ray diffraction study (XRD), field emission scanning electron microscopy (FESEM) has been used to analyse the phases evolved during various stages of milling. The crystallite size and lattice strain were analyzed by Williamson-Hall method and finally, the structures and Phases are correlated. Sharp peaks with high intensity reveal the presence of amorphous and crystalline phases. For alloy B, intermetallic peaks like Al3Fe, andAl3Ti, Y2O3 and TiO2 for alloy C has been observed after sintering. |
