M2052 alloys can absorb external vibrational energy, thereby reducing machine system vibration and noise. Theutilization of laser powder bed fusion for the preparation of M2052 alloys holds promise for meeting the servicerequirements of aerospace precision equipment. The fundamental forming process characteristics of the M2052 alloy weresystematically investigated, the factors leading to defect formation were explained, and the microstructure and phasecomposition of the M2052 alloy were analysed. An evaluation of the tensile properties was then conducted on the basis ofthese findings. These results indicate that the process window for the laser powder bed fusion of the M2052 alloy isexceedingly narrow. A lack of fusion occurs because of insufficient laser input energy, whereas the occurrence of cracks isattributed to inappropriate parameter combinations. The as-deposited alloy displays fine cellular dendrites, along with atrend of columnar crystal growth, exhibiting a pronounced [100] grain orientation and forming a single γ-(Mn, Cu) solidsolution phase. The yield strength is (345±5) MPa, the ultimate tensile strength is (404±2) MPa, and the elongation is 5.21%±0.57% at room temperature, demonstrating characteristics of brittle fracture. The primary reasons for M2052 alloybrittle fracture are the formation of numerous microcracks and holes.
