Abstract
A block Ni-Cr-Al superalloy foam with dimensions of 300 mm (width direction, WD) × 500 mm (rolling direction, RD) × 60 mm (normal direction, ND) was fabricated using powder alloying, multi-sheet stacking, and hot rolling processes. The structural characteristics, microstructure, and mechanical asymmetry of the block Ni-based foam were investigated......
