Squeeze casting of electromagnetically stirred aluminum matrix nanocomposites in semi-solid condition using hybrid algorithm optimized parameters

Abstract

The government mandated fuel efficiency standards for automobile manufacturers reinforce the incentives to reduce the fuel consumption of their vehicles and minimize CO2 greenhouse emission, which requires developing the lighter vehicles, while preserving product performance and cost objectives. One of the effective means to address this challenge has been the design and application of lightweight materials including AMNCs for the automotive parts. Multiple methods have been introduced to manufacture AMNCs such as compocasting in which the reinforcement particles are added to a solidifying melt while being agitated by the electromagnetic field in EMS apparatus. The slurry is then poured into the die cavity and squeezed during the solidification. This research employs ANFIS-PSO in order to optimize the parameters in compocast processing of AMNCs. The objective function is calculated and minimized by ANFIS and PSO, respectively. The optimized electromagnetic stirring process was used to produce the AMNCs with superior wear resistance.
