Abstract [en]
The current work is focused to ascertain the impact on the mechanical and morphological characteristics of hypoeutectic alloy Al–Ni with a range of solution treatment temperatures. Al, Ni, Si, and Mg of necessary weight percentages were melted in a crucible (make–clay graphite) and were cast. The cast alloys were then solutionised for 8 h from 450 to 550 °C, quenched and was aged for 12 h at 170 °C. The fractography, intermediate phase and the elementary composition of alloy was determined. It was observed from the investigation that a rise in solutionising temperature caused grain refinement in the developed hypoeutectic alloys. A surge in the value of hardness was observed with respect to the rise in solutionising temperature. It was also noticed from the analysis that the value of tensile strength, yield strength, ductility and impact resistance of the hypoeutectic alloys enhanced with temperature rise from 480 to 510 °C and then declined from 510 to 550 °C.
