Eutectic Superalloys for Laser Powder Bed Fusion [PDF]
Due to the small freezing range of eutectic alloys, the Cotac-type alloys might be viable alternatives to conventional Ni-based superalloys when processed through additive manufacturing. Laser-pass assessment reveals that both Cotac-74 and Cotac-744 display improved cracking resistance when compared to the conventional Ni-based superalloy CM247LC ...

Development of Control Systems for Laser Powder Bed Fusion
The International Journal of Advanced Manufacturing Technology, 2023 Abstract This article aims to highlight the development of an intermittent controller designed to compensate and rectify the lack of fusion (LoF) zones that induce during the LPBF process. The initial step involved the utilization of the Self-Organizing Map (SOM) algorithm to identify the location of LoF defects.
