چکیده مقاله
This research presents the development and characterization of an innovative CoNi basedhigh entropy superalloy optimized for Laser Powder Bed Fusion L PBF technology Leveraging principles of high entropy alloys HEAs , the alloy composition comprisingCo, Ni, Cr, Al, V, Ti, Ta, and W is tailored to meet the rigorous demands of sustainableapplications Through a systematic investigation of process parameters, a processwindow is established to achieve parts with superior mechanical properties, includingtensile strength exceeding 1 GPa and ductility exceeding 30% at room temperature in asbuiltcondition Additionally, compression tests reveal remarkable yield strengthretention up to 700°C Microstructural analysis based on EBSD and TEM confirms theformation of a single phase fcc solid solution without any topologically close packed TCP phases and remarkable segregation, highlighting the alloy's crack resistant natureand high density achievable via L PBF The alloy's design principles, supported bycalculation of phase diagram CALPHAD using HEA database, underline its potentialfor high performance component production in critical industries
