The Chmielus Advanced Manufacturing & Magnetic Materials Lab (AM³, www.chmieluslab.org) is focused on the influences and relationship of composition, impurities, manufacturing,
and processing parameters on the microstructure and properties of structural and multifunctional metals in bulk, foam, thin films, and single crystalline form with a focus on 3D structures produced by additive manufacturing.
In additive manufacturing, we work on identifying the effects of powder properties, printing and processing parameters on green and further processed (e.g. sintering and aging) samples’ microstructure, porosity, residual stresses, mechanical,
fatigue and multifunctional properties. We focus on all aspects of binder jet 3D printing and sintering but also use direct energy deposition, and selective laser melting/sintering and built custom-made printers for very small print volumes
and magnetic materials. We have expertise working with a large variety of materials including Ni-based, Ti-, Cr-Co-alloys and other biocompatible materials, steels, carbides, multifunctional Heusler alloys.
The main focuses of this research group in functional materials is in ferromagnetic shape-memory alloys, high temperature shape memory, and magnetocaloric materials. We are mostly interested in microstructure, phase transformations, mechanical,
thermal, magnetic properties.
In metal thin films and coatings, we are mostly interested in the effects of impurities and processing parameters on as-deposited films, but also phase-transformations, texture transformations and final properties, including resistivity,
magnetization, texture, and mechanical properties. Furthermore, we investigate stresses during deposition and cycling.
