aceFrom scrap to prime: Designing high-performance alloys from dirty feedstocks with machine learning
Producing alloys from recycled metals via secondary synthesis can markedly cut energy use, greenhouse-gas emissions, and dependence on scarce, strategically important elements relative to primary routes. The central obstacle is the feedstock itself: Scrap is chemically heterogeneous and unpredictable, a "dirty" mix whose impurities typically embrittle materials. Conventional strategies address this challenge by diluting impurities through the addition of virgin material, thereby restricting scrap utilization, li…
Deep-neural-network optimization identified processing windows in which contaminated scrap iron stays ductile and strong, with reported 8.1% lower manufacturing cost and tensile and elongation gains.
The demonstration uses a single model ductile iron representing contaminated scrap, so the source does not show that the results extend to other alloys or industrial-scale production.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-1920 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
