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 jobLTT 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 optical microscopy (LOM) to examine printing defects and dilution, Vickers hardness measurements, and electron backscatter diffraction (EBSD) on selected specimens, including reconstruction of prior-austenite grains. More recently, cubes have also been produced by laser powder bed fusion (LPBF) using two of the alloy powders. Microstructural characterisation of these specimens by LOM is currently in progress. You will bring the existing and emerging results together to investigate the relationships between processing, microstructure, printing quality and hardness. The work will include identifying the most valuable scientific questions, establishing where the DED and LPBF results can be meaningfully compared, and completing focused complementary characterisation. The main outcome should be one or more full-length manuscripts prepared and submitted to a relevant peer-reviewed journal. Duties of the positionOne of the main objectives of SFI PhysMet is to explore and develop innovative processing and joining methods with enhanced sustainability and competitiveness. You will contribute to this aim through the following activities: Review, consolidate and document the existing specimens, processing information and characterisation results. Define a focused plan for completing the study, identifying the additional analyses or experiments needed to support its scientific conclusions. Carry out and analyse complementary microstructural characterisation and strength property  measurements in collaboration with the project team. Investigate the effects of alloy composition, processing conditions, dilution and repeated thermal cycles on microstructure and hardness, using the available evidence. Develop a scientifically justified comparison of the DED and LPBF results for the alloys studied by both processes. Lead the interpretation of the results and the preparation and submission of at least one full-length journal manuscript in collaboration with the project team. Communicate the findings through project meetings and relevant scientific conferences and document the data and analysis procedures for future use. You will work closely with colleagues and partners within SFI PhysMet. Research visits and participation in relevant conferences are encouraged as opportunities to strengthen the study, exchange knowledge and expand your scientific network. Required selection criteriaA PhD in materials science and engineering, metallurgy, welding technology, mechanical engineering or a closely related discipline, or documented scientific qualifications at an equivalent level. Relevant experimental research experience in welding metallurgy, metal additive manufacturing or a related field involving solidification and phase transformations in metallic materials. Hands-on experience with metallographic sample preparation and microstructural characterisation of metallic materials, by light optical and electron microscopy methods. Demonstrated ability to analyse experimental data independently and relate processing conditions, microstructure and material properties. Experience in scientific writing, demonstrated by relevant publications, and the ability to take a leading role in manuscript preparation. Excellent written and oral English communication skills. Preferred selection criteriaWe welcome applicants with different combinations of the following experience: Experience with DED and/or LPBF, including interpretation of processing parameters and thermal histories.
