Laser sintering (LS) is the dominant powder-based method for additive manufacturing (AM) of metallic components that is already found in industrial application for high performance components. Masoud Rashidi’s current research focuses on powder characteristics and metallurgical principles for materials being processed by AM. To do this the microstructure of the additively manufactured components from Ni-base superalloys (e.g. IN625, IN718, and IN738) and stainless steels (e.g. grade 316) are characterized using X-ray Photoelectron Spectroscopy (XPS), Auger Electron Spectroscopy (AES), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Atom Probe Tomography (APT). The aim of the project is to develop methodology for rapid development of the Ni-based alloys with tailored properties for specific applications, produced by LS.Masoud Rashidi was awarded PhD in Materials Science and Engineering at Chalmers University of Technology in 2017. The PhD aimed at developing a new generation of creep resistant 9–12%Cr steels for applications in critical components of thermal power plants. The research was done a close collaboration between Chalmers Technical University, Siemens Industrial Turbomachinery and Technical University of Denmark and the partners of the Z-Ultra consortium: Saarschmiede GmbH, Fraunhofer Institute of Mechanics of Materials, RWE power AG, Paton Electric Welding Institute, Technical University of Graz, Engineering Academy of Armenia, Georgian Technical University, IPP center LLC, and the Institute of Physics of Materials of the Academy of Sciences of Czech Republic. The study aimed at evaluating the feasibility of using precipitates of a thermodynamically stable phase, Z-phase (CrTaN), as strengthening agent to achieve proper creep strength at steam temperature of 650°C. Masoud Rashidi contributed to the development of more than 10 trial steels mainly by investigating the microstructure using SEM, TEM, and APT.Masoud Rashidi got his MSc degree in Materials Science and Engineering from KTH-Royal Institute of Technology in 2013. His master thesis project was done in a collaboration between Linköping University, Sapa Technology and TitanX Engines cooling. The goal of the research was to investigate the role of heat treatment on the microstructure and mechanical properties of Al-Mg-Si alloys.
