Critical Raw Material Substitution in Permanent Magnets; Next-generation R&D; Evidence synthesis; Reproducibility; Research methodologyAbstract
Critical Raw Material Substitution in Permanent Magnets has moved quickly from a niche engineering question to something a
wider community can now investigate with reasonably reliable tools, but the evidence behind it has not always kept pace. We pull
together the current evidence for critical raw material substitution in permanent magnets, covering the methodological, practical,
regulatory and cost angles, with an eye on where practice has genuinely settled and where engineers and reviewers are still
largely working it out for themselves. Selective, context-specific adoption looks better supported by the evidence gathered here
than either broad rollout or blanket avoidance.
