Here, we quantify the hydrogen distribution in fully \\b{eta} and {\\alpha}+\\b{eta} Ti-Mo alloys by using atom probe tomography. Hydrogen does not segregate at grain boundaries in the fully \\b{eta} sample but segregates at some {\\alpha}/\\b{eta} phase boundaries with a composition exceeding 20 at.% in the {\\alpha}+\\b{eta} sample. No stable hydrides were observed in either sample. The hydrogen concentration in \\b{eta} phases linearly decreases from ~13 at. % to ~4 at. % with increasing Mo-content, which is ascribed to the su"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.00981","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
