Research Projects

The proposed research aims to utilize red mud, a solid waste material produced during alumina production in the bauxite industry, to produce a nano-structured hybrid high entropy alloy with improved mechanical properties. The waste contains around 45-55% Fe2O3, 10.69% TiO2, 20.42% Al2O3, 8.72% SiO2, and other oxides. The project aims to maximize the benefit of dispersion of red mud particles in AlFeTiCoCr High Entropy Alloys by producing a nano-structured hybrid high entropy alloy with improved mechanical properties suitable for structural applications. The project will use supervised machine learning (LM) algorithms to predict the mechanical behavior of the high entropy alloy with and without nano dispersions of redbud particles. The main experiments will involve milling high energy ball mill elements in equi-atomic percentage, synthesizing HEA and red mud dispersoids separately and milling together to produce particle dispersed HEA. Powder samples will be collected for XRD analysis at regular intervals of ball milling, and mechanical alloyed powders will be consolidated in a spark plasma sintering machine. The experimental density of the consolidated pellet will be calculated using Archimedes' principle. The research's significance lies in its potential applications in various sectors, such as automobile, mining, mineral, aerospace, defense, and more. The developed HEAs can be effectively used in various industries due to their excellent combination of properties.
