  Physics-informed machine learning prediction of the martensitic transformation temperature for the design of “NiTi-like” high entropy shape memory alloys 

  Article dans une revue avec comité de lecture

  THIERCELIN, Léo; PELTIER, Laurent; MERAGHNI, Foudil (Elsevier BV, 2024-01)

  The present study proposes a physics-informed machine learning (PIML) algorithm-based approach aimed at predicting the martensitic transformation temperature (Ms) for the design of “NiTi-like” high entropy shape memory ...
