Topology, Morphologies, and Material Properties of 40% Aluminium-10% Nickel Boride Alloys as a Function of Recrystallization Rate

The study will involve conducting analyses on microstructures consisting of 40% aluminium and 10% nickel, with variations in the rate of hardening. The aluminium and nickel, both of commercial grade, were subjected to a crucible furnace where they were heated to a temperature of 1600 degrees Celsius until they reached a molten state. The utilization of permanent moulds was necessary for casting the metal at temperatures of 20, 60, and 100 degrees Celsius. In order to document the freezing curvature of the castings, a centralized data collection technique was implemented. The microstructure and mechanical properties of this alloy were examined by researchers. The rate of solidification was observed to increase and the duration of the process was observed to decrease as the temperature of the mould was reduced. The microstructure has been modified due to disparities in solidification rates. An increase in the rate of solidification leads to a reduction in the spacing between secondary dendritic arms, hence leading in an enhancement of strength. The hardness of the product exhibited an increasing trend as the distance from its center to its edges grew.
