The Ni-based bulk metallic glasses (BMGs(Ni39Zr 16Ti13Nb7Si3Sn2)) modified by Al, Hf and W have been synthesized for a specific application of penetrating materials. When Al was replaced with Zr of the Ni 59Zr16Ti13Nb7Si3Sn 2 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 Ni39Zr16Ti13Nb 7Si3 Sn2 BMG, the 7 mm amorphous BMG specimen was obtained. For the Al modified BMG (Ni59Zr15Ti 13Nb7Si3Sn2Al1). 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.
