Simulating the future of manufacturing. My research harnesses the power of Multiphysics to create digital twins of advanced processes like laser cladding and additive manufacturing. I develop high-fidelity models to predict thermal stress, melt pool dynamics, and microstructure evolution, specifically for depositing novel High-Entropy Alloys (HEAs). This computational approach allows me to solve complex engineering challenges and optimize the creation of next-generation, high-performance materials and components.
I use JMatPro to predict temperature-dependent thermophysical properties and generate CALPHAD-based phase diagrams for customized alloys. My work extracts key inputs — thermal conductivity, specific heat, density, melting/solidification ranges and other temperature-dependent properties — to feed process and microstructure simulations and to interpret experiments. I apply these tools to novel materials, especially high-entropy alloys (HEAs) and functionally graded materials (FGMs), enabling rapid evaluation of composition–temperature spaces and guiding alloy design. These computational predictions are integrated with phase-field and microstructural analyses to support parameter selection in additive manufacturing and to optimise surface-coating strategies.
Additive manufacturing combines process development, materials science, and quality assurance to fabricate complex parts layer-by-layer. Important elements are process technologies (laser cladding, directed energy deposition, powder-bed fusion), process-structure-property studies, parameter optimization and design of experiments, powder feedstock development (including HEAs), in-situ monitoring and control, and post-processing (heat treatment, machining, surface finishing). The focus is on achieving repeatable microstructures, tailored mechanical/tribological performance, and scalable, industry-ready manufacturing routes.
Multiphysics modeling couples interacting physical phenomena to accurately simulate real-world processing and performance. Typical problems include thermal–fluid–solid coupling for melt-pool dynamics and solidification, phase-change and microstructure prediction, Eulerian/Lagrangian particle tracking for sprays and powders, electromagnetic–thermal coupling for induction/laser heating, and structural response under service loads. Standard tools and approaches you’ll encounter are COMSOL Multiphysics, ANSYS/Fluent, OpenFOAM, discrete-phase and continuum-coupled models, and parametric studies to link process settings to outcomes.
Surface engineering aims to tailor surface chemistry, microstructure, and texture to improve wear, corrosion, and fatigue resistance. Topics include thermal spray and laser-based coating methods (laser cladding of HEAs), surface modification (peening, laser remelting), characterization techniques (SEM, XRD, microhardness, Barkhausen noise, eddy-current NDT), tribology and wear testing, and coating optimization for industrial applications. Emphasis is on achieving robust adhesion, controlled dilution, graded microstructures, and performance validation under application-relevant conditions.
