This study investigated the manufacturing conditions and properties of Ti47Cu38Zr7.5Fe2.5Sn2Si1Ag2amorphous bulk metallic glass (BMG) to examine its applicability for scalpels for medical use. Ti-base BMGalloys have excellent mechanical properties and biocompatibility, making them a suitable scalpel material. In this study, a vacuum suction casting method was used to manufacture a BMG alloy scalpel. Afterexamining various manufacturing conditions, to successfully suppress the occurrence of pores andmanufacture a BMG with excellent shape the optimal conditions were determined to be 236 A of arc current,20 s of melting time, 2 s of suction time, 10°C of coolant temperature, and -0.1 MPa of suction pressure. XRDanalysis confirmed that the Ti-base BMG had a completely amorphous structure. Vickers hardnessmeasurements showed that the Ti47Cu38Zr7.5Fe2.5Sn2Si1Ag2 amorphous bulk metal material (BMG) scalpel hada hardness of 781 Hv, and was superior to a commercial stainless steel (SUS) scalpel in terms of durability. In the pork skin cutting tests, the Ti-base BMG scalpel maintained its edge without chipping, while the SUSscalpel showed chipping and an uneven cutting surface. These research results suggest that Ti-based BMGcan provide better high-strength performance and durability than commercial SUS scalpels, and demonstrateits potential for application as a medical tool. However, bulk amorphous alloys with excellent glass formability(GFA) still require a detailed study of the optimal fabrication conditions to avoid pores and defects. KCI Citation Count: 0
