MAGNIFICENT-Additively manufactured Magnetic High Entropy Alloys for Renewable Electricity

MAGNIFICENT-Additively manufactured Magnetic High Entropy Alloys for Renewable Electricity

The aim ogf the project is to produce magnetic materials with superior and long-lasting magnetic properties based on high entropy alloys (HEA), using machine learning and additive manufacturing for materials selection and synthesis as well as high throughput materials characterisation at the micro and nano level.

Soft magnets are basic constituents in smart devices which are important for digitising our society, boosting circular economy and a global renewable energy system. However, non-ideal magnetic properties may lead to fatigue and loss of efficiency or even mechanical failure. HEAs are materials with unexplored compositional fields which may offer unexpected and promising properties and functionalities compared to existing soft magnets.

Sub-objectives:

  • Achieve permeability in the order of 106, coercivity < 1 Am-1 in both plane axes, magnetization saturation of ≈ 2T and magnetostriction in both directions < 1 ppm, accumulated residual stresses < 10 MPa and a spatial 3-D distribution gradient < 1%.
  • Identify and optimise critical parameters for producing suitable compositions and shapes of HEA soft magnets with additive manufacturing and post processing treatment.
  • Establish health and safety protocols for HEA powders in line with responsible research and innovation (RRI) principles and life cycle considerations in existing national and European directives.
  • Promote theoretical and methodological renewal and national competence in magnetic materials research.
  • Create first-principles tools for exploration of entropy-stabilized alloys.
