microstructuurengineering

Microstructure engineering is a field within materials science that aims to tailor the internal structure of materials at the micron and submicron scales to achieve specified properties. It focuses on manipulating grains, phases, precipitates, and defects through processing.

It relies on controlling processing steps such as alloy design, casting or powder processing, thermomechanical processing, heat treatment, deformation, and aging. Techniques like precipitation hardening, martensitic transformations, phase separation, and grain-boundary engineering are common.

Characterization and modelling are essential. Microscopy (optical, scanning electron microscopy, transmission electron microscopy) and EBSD (electron backscatter diffraction) reveal grain size, texture, and phase distribution; atom probe tomography provides composition at near-atomic scale. Computational tools include phase diagrams, kinetic models, phase-field simulations, and crystal plasticity. Additive manufacturing, with rapid solidification and layer-by-layer processing, offers new opportunities for microstructure control.

Applications span aerospace and automotive components, turbines, electronics, and energy storage, where properties such as strength, toughness, creep resistance, fatigue life, and corrosion resistance are critical. Challenges include multi-scale complexity, trade-offs between properties, reproducibility, and cost. Ongoing research combines experimental, computational, and data-driven approaches to enable predictive design of microstructures.
