“…The microstructure of the specimens was studied by optic microscopy with an Olympus BX 51 (Olympus Corp., Tokyo, Japan) and scanning electron microscopy with a Phenom ProX (Phenom-World BV, Eindhoven, The Netherlands). Chemical composition of the alloy Zr 59 Cu 14.3 Ni 11.9 Al 9.3 Nb 5.5 was confirmed by energy-dispersive analysis (EDX) in [26]. In addition, the content of oxygen was measured by the method of the reductive melting of the material in a helium flow using a Leco TC-600 analyzer (LECO Corporation, St. Joseph, MI, USA).…”

Zr57Cu15Ni10Nb5 (more known as Vit-106) is a promising zirconium-based alloy with a high glass-forming ability, and belongs to the so-called bulk metallic glasses (BMG). Workpieces with a size of around one centimeter in all three dimensions can be obtained from a BMG alloy by casting. However, further increasing the cast size decreases the cooling rate and thus induces crystallization. Selective laser melting (SLM) is a well-known technique to overcome size limitations for BMGs because a workpiece is built by the addition of multiple melt portions in which the cooling rate is kept above the critical one. Currently, BMG parts obtained by SLM suffer from partial crystallization. The present work studies the influence of SLM process parameters on the partial crystallization of Vit-106 by metallography and the influence of the microstructure on mechanical properties by microhardness and wear resistance testing. Submicron crystalline inclusions are observed in an amorphous matrix of a Vit-106 alloy obtained by SLM. The size and the concentration of the inclusions can be controlled by varying the laser scanning speed. It is shown that submicron crystalline inclusions formed in the amorphous matrix during SLM can favorably affect microhardness and wear resistance.
