Bulk metallic glasses for industrial products; New structural and functional applications

“…Ti-based BMGs such as Ti-Cu-Ni-Sn [16] and Ti-Zr-Cu-Ni-Al-Si-B [17] are most applicable for the materials of transportation equipment due to their high strength and relatively lightweight. However, there remains difficulty to apply Ti-based BMGs for industrial materials.…”

“…In fact, this elastic deformation behavior has an advantage for the designing allowable stress and factor of safety, but its fracture manner has disadvantages for designing under limit-state, fatigue and impact stresses. Figure 6 shows XRD profile of the newly developed alloy with a diameter of 3 mm, together with the glassy alloy [17] with a diameter of 2 mm, and the β-Ti alloy [22] with a diameter of 3 mm. For example, adding element [18] and embedding reinforcement particle [19] or fibers [20] are employed in order to form glass/crystalline composites.…”

“…As a result, it is found that a cast new alloy with a nominal composition of Ti 52 Cu 23 Ni 11 Mo 7 Fe 7 exhibits high yield and fracture strength, and large plastic elongation. 23) Figure 6 shows XRD profile of the newly developed alloy with a diameter of 3 mm, together with the glassy alloy 17) with a diameter of 2 mm, and the -Ti alloy 22) with a diameter of 3 mm. For the glassy alloy, XRD profile shows only a broad peak revealing a single glassy structure.…”

“…3.3 Nonequilibrium Ti-based crystalline alloy with high strength and good ductility Ti-based BMGs such as Ti-Cu-Ni-Sn 16) and Ti-Zr-Cu-NiAl-Si-B 17) are most applicable for the materials of transportation equipment due to their high strength and relatively lightweight. However, there remains difficulty to apply Tibased BMGs for industrial materials.…”
