1. Additively Manufactured Rare Earth Free Permanent Magnets
University essay from Uppsala universitet/Tillämpad materialvetenskap; Uppsala universitet/Oorganisk kemiAbstract : It’s well known that MnAl(C) material consists of a metastable phase (τ) with promising ferromagnetic properties, produced either by controlled cooling from the high-temperature hexagonal ε-phase or rapid cooling that freezes the ε-phase followed by low-temperature annealing. Due to the high cooling rates involved, additive manufacturing (AM) especially selective laser melting (SLM), has been identified as a possible method to retain the high-temperature ε-phase, hence containing a potential capacity to produce permanent magnets upon low-temperature annealing.

2. Internal strain in the magnetocaloric alloy MnCoSi
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : Cooling systems based on magnetic refrigeration are a promising and environmentally friendly alternative to commonly used gas-compression refrigeration. Magnetic refrigeration is based on the magnetocaloric effect. READ MORE

3. The development of scanning X-ray diffraction phase mapping techniques using automated Rietveld refinements.
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : A methodology for determining inhomogeneities in microstructural features has been established using scanning X-ray diffraction (SXRD) and automated Rietveld refinements. The method has proven successful for spatially resolved quantitative phase analysis or "phase mapping" of retained austenite on a variety of martensitic steel samples, including carbon case-hardened steel bars and quenching and partitioning (Q&P) steel sheets.
