Description
Aydogan and colleagues built a new refractory alloy in 2026 by laser-based 3D printing and tested whether it can survive the radiation inside future nuclear reactors. The alloy mixes chromium, molybdenum, tantalum, titanium, and vanadium. Its printed structure forms a branched main phase plus a second oxygen-rich phase, and printing gave it both higher strength and better ductility than cast versions.
Even at one thousand degrees Celsius the alloy kept a yield strength of about nine hundred fifty megapascals while still deforming without cracking. Under radiation doses up to eighteen displacements per atom, at room temperature and at six hundred fifty degrees, both phases stayed stable with no voids or phase changes. Damage loops formed but stayed controlled, helped by slow atom movement in the mixed matrix. The authors see promise for fission and fusion reactor parts.
