“…It was reported that both the compressive strength and the plastic strain prior to fracture of the Zr-based [12][13][14], CuZr-based [15], Cu-based [16], Ni-based [17], and Ti-based [18] BMGs, increase upon temperature decreasing, whereas the plasticity of Ce-based BMGs1 [9] declines at cryogenic temperatures. The studies of the tensile properties of Zr 41 Ti 14 Cu 12.5 Ni 10 Be 22.5 at room and low temperatures showed that the tensile strength of the BMG at room temperature is higher than that at cryogenic temperature [20]. While Kawashima et al [11] obtained different conclusions in Zr-Cu-Al system, and they reported that the tensile strength and elongation of the alloy increase with decreasing testing temperature.…”

The fluidity and filling ability of glass-forming Zr-based alloy melt in copper mould were investigated both theoretically and experimentally. The major factors which affected the flowing behavior of the metallic melt in the mold were determined, which provides the foundation for overcoming the contradiction between the filling and formation of amorphous alloy during the rapid cooling process of the metallic melts. The casting factors to prepare a metallic ring were discussed and selected. As a result, a Zr-based bulk metallic glass ring was prepared successfully.Zr-based bulk metallic glass, casting, fluidity, moldingThe earliest amorphous alloy was discovered in the 1960s by quenching Ag 80 Si 20 melt [1] . Due to the limitation of the cooling rate, amorphous alloys can only be made in the form of ribbons and powders which limit the application severely in the earlier years. Since the discovery of La-based and Zr-based bulk metallic glass (BMG) systems [2][3][4][5] by Inoue and Johnson respectively, the limitation of cooling rate was broken up. Later, the Pb 40 Cu 30 Ni 10 P 20 bulk amorphous alloy with a thickness of 72 mm was made by replacing Ni in Pb 40 Ni 40 P 20 by 30% Cu in Inoue's group [6] . The critical cooling rate was measured to be only about 0.33 K/s by Johnson's group [7] . The above mentioned research tremendously contributed to the preparation of BMGs in a large size.Due to the special structure of BMGs, BMGs have different properties from conventional crystalline alloys, such as high strength, high hardness, high elastic limitation and high fracture toughness, and superplasticity in a supercooled liquid region. Meanwhile, BMGs also have other favorable properties such as wear resistance, corrosion resistance, radialization resistance and antioxidation. These properties attract extensive attention in the metallic materials field [8][9][10] . In

“…With the characteristics of high strength, high hardness, excellent wear resistance, and good elasticity, bulk metallic glasses (BMGs) are envisaged to have a wide range of functional and structural applications [1][2][3]. Because of the lack of the effective plastic deformation at room temperature, BMGs are restricted in practical applications.…”

Deformation of the bulk metallic glasses (BMGs) and the creation and propagation of the shear bands are closely interconnected. Shearing force was loaded on Zr 41.2 Ti 13.8 Cu 12.5 Ni 10.0 Be 22.5 (Vit.1) BMGs by cutting during the turning of the BMG rod. The temperature rise of alloy on the shear bands was calculated and the result showed that it could reach the temperature of the super-cooled liquid zone or exceed the melting point. The temperature rise caused viscous fluid flow and brought about the deformation of BMGs. This suggested that the deformation of BMGs was derived, at least to some extent, from the adiabatic shear temperature rise. deformation, shear bands, temperature rise, metallic glasses PACS: 62.20.F-, 61.43.Dq, 65.60.+a, 81.05.Kf
