Description
Yuxue Wu and co-authors study fatigue cracks in a printed titanium alloy in a paper from 2024. The alloy, TC11, was built up by laser metal deposition and then double annealed. Its inner structure mixes round crystals with tall columnar ones. A basket-like phase inside adds fine plates and needles.
Crack growth speed shifted with that mixed structure. Round crystals deformed more often, which sped cracks along. Columnar crystals spread the strain more evenly and slowed cracks. The team read slip patterns to explain the split. Tuning the crystal mix could make printed titanium last longer under repeated loads. That matters for aircraft and engine parts made by printing.
