논문 초록 (Abstract)
The Ni-based bulk metallic glasses (BMGs(Ni59Zr16Ti13Nb7Si3Sn2)) modified by Al, Hf and W have been synthesized for a specific application of penetrating materials. When Al was replaced with Zr of the Ni59Zr16Ti13Nb7Si3Sn2 BMG, a large glass forming ability was observed, enabling to fabricate 7 mm cylindrical amorphous specimen. Also, when Hf or W was replaced with Ni of the Ni59Zr16Ti13Nb7Si3Sn2 BMG, the 7 mm amorphous BMG specimen was obtained. For the Al modified BMG (Ni59Zr15Ti13Nb7Si3Sn2Al1), a high strength of 2:6 GPa with 10% plastic strain was observed. It appears that the Hf modified BMG showed an excellent candidate for the application of penetrating materials among the examined BMGs.
