Zr-based bulk metallic glasses attract the attention because of their good mechanical properties and glass-forming ability. A laser welding process has been applied to increase the capability of using amorphous materials in the industry. The plates of Zr₅₅Al₁₀Ni₅Cu₃₀ alloy were produced by die pressure casting method and welded by the TruLaser Station 5004. X-ray analysis and microscopic observation provided information about the structure and morphology of the cross-section of weld on the boundary of the heat affected zone and the fusion zone. Nanohardness and reduced Young modulus of the particular heat affected zone, fusion zone, and parent material were examined with Hysitron TI950 Triboindenter and with the Berkovich indenter. The presence of the amorphous and amorphous-crystalline phases was confirmed by related tests. The detailed topographic analysis revealed that the heat affected zone demonstrated a slight roughness characteristic of the crystalline phase and a smooth surface in the fusion zone. The main value of the nanohardness of particular weld zones has the similar order of magnitude. In turn, Er value is restricted in the range of 105.76-108.80 GPa. The main goal of this work is to present the structure and chosen nanomechanical properties of the Zr₅₅Cu₃₀Ni₅Al₁₀ laser weld.
