Tailoring the Mechanical Properties of L‐DED‐Fabricated γ‐TiAl Alloys Through Heat Treatment: Correlating Microstructural Evolution With Fracture Mechanisms
Laser‐directed energy deposition (L‐DED) offers a flexible route for fabricating γ‐TiAl components, but the as‐deposited microstructure requires post‐processing to overcome limited deformation capability. Here, an L‐DED Ti–48Al–2Cr–2Nb alloy was subjected to solution and solution‐aging treatments. Its phase constit...
