Fully amorphous Zr_52.5Cu_17.9Ni_14.6Al₁₀Ti₅ bulk metallic glass (BMG) samples with a relative density exceeding 98% were fabricated via selective laser melting (SLM). High fracture stresses of around 1700 MPa and a reproducible plastic strain of about 0.5% were obtained for cylindrical SLM samples. The analysis of the observed serrations during compressive loading implies that the shear-band dynamics in the additively manufactured samples distinctly differ from those of the as-cast glass. This phenomenon appears to originate from the presence of uniformly dispersed spherical pores as well as from the more pronounced heterogeneity of the glass itself as revealed by instrumented indentation. Despite these heterogeneities, the shear bands are straight and form in the plane of maximum shear stress. Additive manufacturing, hence, might not only allow for producing large BMG samples with complex geometries but also for manipulating their deformation behaviour through tailoring porosity and structural heterogeneity.

全非晶Zr _52.5 Cu _17.9 Ni _14.6 Al ₁₀ Ti ₅通过选择性激光熔化（SLM）制备了相对密度超过98％的块状金属玻璃（BMG）样品。对于圆柱形SLM样品，获得了大约1700 MPa的高断裂应力和大约0.5％的可再现塑性应变。对压缩载荷过程中观察到的锯齿状结构的分析表明，添加制造的样品中的剪切带动力学与铸态玻璃的剪切带动力学明显不同。这种现象似乎是由于均匀分布的球形孔的存在以及仪器压痕显示出的玻璃本身更明显的异质性引起的。尽管存在这些异质性，但剪切带是笔直的，并在最大剪切应力的平面内形成。因此，增材制造
