In this study, we fabricated Ti-Cr and Ti-Cr-Al alloys by the in situ alloying of elemental powders and programmed single-crystal-like textures (&lt;100&gt;, &lt;110&gt;, or &lt;111&gt; // build direction (BD)) via tailored scanning strategies. By employing processing conditions that yielded a melt pool depth far greater than the layer thickness, compositionally uniform builds were achieved through multiple remelting events. In Ti-12Cr (mass%), which has relatively low β-phase stability, the ω phase was observed despite not being detected in its solution-treated-and-quenched counterpart. This observation suggests that the LPBF-specific thermo-mechanical history, including a tensile residual stress of 353 MPa, may have contributed to ω-phase formation. The addition of Al suppressed the formation of ω, resulting in a single-phase β matrix. Furthermore, scan-strategy-dependent textures were consistently observed across all the compositions. The elastic modulus showed pronounced orientation-dependent anisotropy, reaching ∼60 GPa along &lt;100&gt; in a Ti-12Cr-3Al composition, whereas the BD-parallel yield strength approached 800-1,000 MPa depending on the texture, producing elastic admissible strains that surpass those of reported LPBF-fabricated Ti-6Al-4V. Based on these findings, we propose an additive manufacturing process-aware design framework in which alloy composition, LPBF-specific thermo-mechanical history, and crystallographic texture contribute collectively to phase stability and directional mechanical properties in metastable β-Ti alloys.</span></p>

Here, we report an additively manufactured high-entropy alloy (HEA) that integrates structural and catalytic functions within a single material and exhibits intrinsic activity for the reverse water-gas shift reaction in the as-printed state without any post-treatment. By controlling laser irradiation conditions during laser-powder bed fusion, we engineered distinct crystallographic microstructures, including single-crystal-like and polycrystalline textures. The single-crystal-like reactor exhibited approximately 1.7 times higher CO formation rate than its polycrystalline counterpart while maintaining nearly 100% CO selectivity. Surprisingly, this enhanced activity was achieved despite a less favorable surface composition for the RWGS reaction, indicating that catalytic performance cannot be explained by conventional surface chemistry alone. Instead, we show that crystallographic microstructure programs heat transport within the bulk material, thereby determining catalyst surface temperature and catalytic function. Furthermore, prolonged reaction under RWGS conditions induces microstructural evolution involving phase separation, which progressively enhances thermal transport and catalytic performance. We describe this dynamic behavior as self-optimizing catalysis. These findings establish heat transport as a programmable materials function arising from additive-manufacturingengineered microstructures, providing a general design paradigm for adaptive functional materials beyond conventional catalyst design.</p>]]>
