A hatching-distance-controlled lattice of 65.1Co28.2Cr5.3Mo is additively manufactured via laser powder bed fusion with a couple periodic and aperiodic arrangements nodes struts. Thus, the proposed has an amorphous-inspired structure in short- long-range orders. From structural perspective, artificial intelligence algorithm used to effectively align lattices various hatching distances. Then, metastable combination exhibits unexpectedly high specific compression strength that only slightly below solid structure. microstructural newly designed lattice, where thermal energy from irradiation mainly concentrated, exhibit equiaxial microstructure. By contrast, struts columnar microstructure, thereby allowing pass through narrow ligaments. The heterogeneous phase differences between nodal strut areas explain strength-deteriorating mechanism, owing undesirable multi-phase development as-built state. However, solid-solution heat treatment form homogeneous bestows even higher strength. Furthermore, electrochemical leaching leads formation nanovesicles on surface microporous system, leading large area. more advanced valve cage for use power plant by using both (i) preserve its mechanical stiffness (ii) actively dissipate generated stress area provided nanovesicles.
