Project Abstract

The integration of graphene and ceramic particulates into a lightweight steel matrix aims to significantly enhance mechanical performance and functional properties for automotive applications while addressing sustainability and safety requirements. This study investigates nano- composite reinforced steels synthesized through a hybrid processing route that combines high-energy mechanical alloying and ultra-high-temperature consolidation to achieve a uniform dispersion of graphene nanoplatelets (GNPs) and ceramic reinforcements (such as SiC and Al2O3) at a controlled volume fraction. The research evaluates microstructural evolution, interfacial bonding, and defect mechanisms using advanced characterization techniques including scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy, and electron backscatter diffraction (EBSD). Mechanical performance is assessed through tensile, fatigue, impact, and hardness testing across a range of strain rates and elevated temperatures to simulate real-world automotive service conditions. Complementary assessments of wear resistance, friction behavior, and density are conducted to quantify weight reduction benefits and durability under tribological stresses typical of engine and drivetrain components. A key focus is on achieving a percolation- free, nanoscale dispersion of graphene to maximize load transfer, improve ductility, and mitigate crack initiation and propagation, while ceramic particulates provide enhanced stiffness, thermal stability, and oxidation resistance. The study also examines the effects of graphene functionalization, surface treatment of ceramic particulates, and processing parameters (milling time, atmosphere, consolidation pressure, and temperature) on the interfacial synergy and load-bearing capacity. Finite element modeling and multiscale simulations are employed to predict effective modulus, yield strength, and fracture toughness as a function of reinforcement distribution and interface strength, guiding experimental optimization. Environmental and economic analyses evaluate the lifecycle implications, recyclability, and potential reduction in fuel consumption due to weight savings without compromising safety margins in crash scenarios. The research addresses reliability under cyclic thermal loads and moisture exposure, with accelerated aging tests to determine long-term performance. Expected outcomes include a tunable balance between strength and ductility, enhanced high-temperature performance, improved wear resistance, and a measurable reduction in greenhouse gas emissions through lighter, safer, and more economical automotive components. The project contributes to materials design principles for nano- composite steel systems, establishes processing-structure- property relationships for graphene- ceramic reinforced matrices, and provides a practical framework for scaling to industrial production while meeting stringent automotive standards.

Project Overview

What This Project Is About

---

This project looks at making steel lighter yet strong by adding tiny amounts of graphene and ceramic particles. Graphene is a single layer of carbon atoms that is incredibly strong and conducts heat well. Ceramic particulates are small ceramic powders that can improve hardness and wear resistance. The idea is to mix these tiny reinforcements into steel to create a material that performs better in cars—being lighter saves fuel, while strength and durability help safety and longevity.
