Due to their superior strength, hardness and elastic strain limit, bulk metallic glass matrix composites are advocated as a material of the future. Nevertheless, they have low strength that renders them unusable in every application of structural engineering. Inoculation has been used to resolve this issue as an efficient means. Due to heterogeneous nucleation, Zr47.5Cu45.5Al5Co2 bulk metallic glass matrix composites (BMGMC) inoculated with ZrC have shown significant refinement in microstructure. Efforts have also been made to exploit modern development of laser-based metal additives BMGMC parts should be manufactured in one phase. The impact of laser treatment on inoculated material is unclear, however. An attempt was made in this study to apply laser-based additive production on untreated and inoculated BMGMC samples. Laser treatment not only refined the microstructure, but also resulted in a change in the scale, morphology and dispersion of the base metal CuZr B2 phase, the heat-affected zone and the fusion zone. The morphology of CuZr B2 changed from spheroid to spherulite only when the laser power was 500 W and no inoculation was observed under the influence of extreme heat. Inoculation has been shown to resist changes in phase morphology in melted and rapidly solidified phases. No evidence of spherulites was found in the material in samples treated with ZrC. This influence, this effect Back-scattered electron imaging is reported. This provides a basis for further analysis in order to Quantify this phenomenon and the growth of full-scale components.
