Video: https://www.youtube.com/watch?v=_KHQjc4ndas&t=41s About the position We are seeking a researcher with a background in welding, metal additive manufacturing or a related area of physical metallurgy for an approximately one-year position within SFI PhysMet (Centre for Sustainable and Competitive Metallurgical and Manufacturing Industry; www.ntnu.edu/physmet) at the Department of Materials Science and Engineering, NTNU. The position offers the opportunity to take a leading role in an experimental study of low transformation temperature (LTT) alloys. You will build on existing specimens and recent results, shape the remaining investigations and lead the preparation of a full-length journal manuscript together with the project team. We welcome applicants who enjoy connecting microstructural observations with physical metallurgy understanding and transforming experimental findings into clear scientific conclusions. Your immediate leader is Head of Department. About the job LTT alloys undergo transformation from austenite to martensite at relatively low temperatures. The associated volume expansion can counteract thermal contraction and offers a route to managing residual stresses in welding and additive manufacturing. Understanding how processing conditions and repeated thermal cycles affect their microstructure is important for assessing their potential in these applications. The experimental work has so far focused on directed energy deposition (DED). Single tracks, double tracks and small cuboids have been printed from three LTT alloys. Initial characterisation has included sectioning and light opt
