With processes of arc melting, inductive melting and copper mold suction casting, a plate Fe-based bulk amorphous alloy Fe_(60)Co_8Zr_(10)Mo_5W_2B_(15) with a thickness of 1mm was prepared. The surfaces and fractures of the cast bulk amorphous alloy were agleam and with typical metallic luster. The glass transition temperature(T_g), supercooled liquid region(△T_x)and reduced glass transition temperature(T_(rg))of the prepared Fe-based amorphous alloy are 884 K,63 K, and 0.611 respectively. The fracture toughness of the cast bulk amorphous alloy is at the level of 1.6 MPa·m~(1/2).
With processes of arc melting, inductive melting and copper mold suction casting, a plate Fe-based bulk amorphous alloy Fe_ (60) Co_8Zr_ (10) Mo_5W_2B_ (15) with a thickness of 1 mm was prepared. The surfaces and fractures of the cast bulk amorphous alloy were agleam and with typical metallic luster. The glass transition temperature (T_g), supercooled liquid region (ΔT_x) and reduced glass transition temperature (T_ (r_g)) of the prepared Fe-based amorphous alloy are 884 K, 63 K , and 0.611 respectively. The fracture toughness of the cast bulk amorphous alloy is at the level of 1.6 MPa · m ~ (1/2).
