 AFECO-NICULHEA was produced using LPBF preallipabra and its microstructural characteristics and tribological properties were investigated under various states. The results showed that the phase of the LPBF specimen consisted of BCC matrix plus CuHB2 precipitate with columnar grains perpendicular to the MPB direction due to epitaxial growth along the temperature gradient. The preferred orientation of the LPBF specimen was gradually transformed as the VED rose, resulting in larger size precipitates and wider MPB upon faster re-melting and steeper cooling. Compared to SPS components, LPBF specimens exhibited better wear resistance due to ultrafine substructure and nanoscale precipitates. The LPBF specimen produced with 83Jmm3 VED had the highest HR and yield stress, H2H3. This article was authored by Yao Jiren, Lu Xinliang, Kuang Shan, and others.
