“…The significantly refined micro-architecture by LPBF is consistent with the expected one due to the rapid solidification processing environment [33]. The greatly refinement in LPBF sample arises significant interfacial density boosting, which presumably leads to the more pronounced composite coupling effect during deformation and confers remarkable enhancement in performances [34,35]. In addition, under the nonequilibrium conditions of LPBF, the composite architecture exhibits short aspect ratios compared to the as-cast counterpart, endowing the integral microstructure and performance isotropized.…”

“…In addition, the LPBF process has an ultra-rapid solidification of more than 10 4 • Cs −1 [30][31][32], which is tens of thousands of times more than that of conventional casting. Under such processing conditions, it is found that, for various metallic in-situ composites, the conspicuous refinement of multiphase grain size shows a promotion for mechanical performances [33][34][35]. This microstructural refinement is bound to rise soft-hard interfacial density dramatically.…”

“…5 . According to reference 18 , the ordered B2 structure can be formed in the as-printed sample. Considering that either Al or Ni typically favors the FCC phase, it is reasonable to hypothesize that the disruption of the B2 ordered structure during the BCC to FCC phase transition may stabilize the resulting FCC phase, leading to irreversibility.…”

“…In metals and alloys, the transition between body-centered cubic (BCC) and face-centered cubic (FCC) crystal structures and its reverse process stand out for their significance 15 , 16 . The reversible FCC–BCC phase transitions are utilized to create diverse material classes, such as steels 4 , catalysts 12 , 17 , and high enthalpy alloys 18 , 19 , for varied applications.…”
