Title : High Entropy Alloys for Additive Manufacturing

Abstract:

High entropy alloys are a new class of promising materials based on the innovative notion of alloying, which is based on the use of numerous primary components in high concentrations (HEAs). So far, numerous HEAs have been identified with qualities that are superior to those of normal alloys, and additional superior high-entropy alloys are likely to be created in the future. However, due to the fundamental needs of HEAs, the production process of HEAs using standard manufacturing processes has considerable constraints. In contrast, additive manufacturing (AM) has opened up new possibilities for creating geometrically complicated HEAs with the ability to adjust their in-situ microstructure characteristics.

 

 

What will audience learn from your presentation?

 

  • This presentation provide the state of the art in AM of HEAs, in light of the increased interest in AM of HEAs in recent years. It explains the feedstock requirements for laser-based additive manufacturing processes. The current situation of practically all HEAs treated by laser metal deposition (LMD), selective laser melting (SLM), and selective electron beam melting (SEBM) is then described.
  • The characteristics of AM-derived microstructures, as well as their exceptional attributes and underlying processes for diverse material processing combinations, are given special emphasis.
  • The post-AM treatments as well as the fabrication procedures for defect-free HEAs are summarised. Finally, a conclusion will be offered on the existing state and future possibilities of additive manufacture of HEAs.

 

Biography:

Dr. Dhanesh G. Mohan is a licensed Professional Engineer (P.E), Chartered Engineer (C.Eng), writer, and educator. He is a Postdoctoral Research Fellow of the Institute of Materials Joining at Shandong University, Jinan, China. His research-based on Net-Zero Manufacturing concepts and mainly focused on Additive Manufacturing (AM) (Friction Stir Additive Manufacturing, 3D printing of high entropy alloys, 3D Composite printing, and Big area additive manufacturing), Surface coating methods, fabrication of high entropy alloys, Corrosion studies, Quantum dots, and Hybrid friction stir welding methods (Laser-assisted FSW, Ultrasonic vibration-assisted FSW, Induction assisted FSW and FSP). To study and understand these methods’ mechanical, metallurgical, corrosive, and microstructural properties on dissimilar metals and alloys (steels, magnesium alloys, aluminium alloys, and high entropy alloys). He wrote more than 30 research articles in SCI-indexed journals and authored 2 books on AM for HEAs and Hybrid FSW.
