Characterization, mechanical properties and dimensional accuracy of a Zr-based bulk metallic glass manufactured via laser powder-bed fusion. Bulk metallic glasses BMGs are high-strength, highly elastic materials due to their disordered atomic structure. Because BMGs require sufficiently high cooling rates to bypass crystallization, laser-based additive manufacturing AM methods have recently been employed for the fabrication of BMGs. A volumetric density of Although the sample was qualified as amorphous via laboratory X-ray diffraction experiments, a more meticulous study using synchrotron radiation revealed nanocrystals in the heat-affected zones HAZs of the melt pool. Fast differential scanning calorimetry FDSC and numerical simulations were then employed to illustrate the mechanism of crystallization. The LPBF-processed alloy revealed excellent mechanical properties, such as high hardness, wear resistance, compressive strength, and flexural strength. Apart from vein-like patterns, the fracture surfaces of the compression test samples showed liquid-like features, which indicate a significant local temperature increase during fracture.

In the past few years, laser powder-bed fusion LPBF of bulk metallic glasses BMGs has gained significant interest because of the high heating and cooling rates inherent to the process, providing the means to bypass the crystallization threshold. The presence of defects and lack of fusion LoF in the near-surface region of the samples resulted in low properties. Comparatively, increasing the core laser power did not have a significant influence. Although increasing the border and core laser power resulted in a higher crystallized fraction, detrimental to the mechanical properties, reducing the formation of LoF defects confirmed using micro-computed tomography, Micro-CT was comparatively more important.
