M&M Extraordinary Associate Professor published in Acta Materialia journal
The Faculty is pleased to share an article authored by Prof Thorsten Becker, Extraordinary Associate Professor in the Department of Mechanical and Mechatronic Engineering. The article covers the current understanding of the structure-property correlations in AM alloys.
The article was published in the prestigious Acta Materialia journal, co-authored by Putin Kumar from the School of Mechanical and Aerospace Engineering, Nanyang Technological University, and Upadrasta Ramamurty from the Institute of Materials Research and Engineering, Agency for Science, Technology and Research, from Singapore. It covers the current understanding of the structure-property correlations in additive manufacturing (AM) alloys.
In a brief overview of the article, Prof Becker explains that additive manufacturing (AM) of metallic components offers many advantages over conventional manufacturing methods, notably design freedom at little material waste. There is significant current interest in the manufacturing aspects of a wide variety of structural alloys. Establishing the processing (microstructure) mechanical performance relations, in conjunction with the attributes such as flaws, residual stresses, and mesostructures inherent to the AM processes, is critical for the widespread adoption of structural metallic components made using AM.
The authors highlight the unique aspects of the microstructures of the AM alloys, process-related attributes, and their effects on the tensile, fracture, fatigue crack growth, and unnotched fatigue properties. The emphasis is on the interplay between the microstructures and process attributes in determining the structural integrity of AM alloys in terms of properties such as near-threshold fatigue crack growth rate, fracture toughness, and fatigue strength.
The Faculty commends Prof Becker and his co-authors for their hard work.
