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 and IN718) 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 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.
