“…Similar structure is found in Al 100−x (T-2) x and Al 100−x (T-8) x alloys with x = 25-50 and 35-40, respectively. Furthermore, the structure of fcc-Al dispersed in an amorphous phase revealed here is not much different from that of Al-(Y,Ce)-Ni-Fe alloys reported previously [15][16][17][18][19].…”

“…8. Kim et al 21) reported the embitterment of nanocrystal/metallic glass composite when the volume fraction of the crystalline phase increased. Basu et al 22) reported that sudden change in mechanical property occurs with the interaction of rigid network of crystalline phases when the volume fraction of the crystalline phase exceed the percolation limit.…”

The microstructures of Cu 60 Zr 30 Ti 10 metallic glass prepared by injection casting and melt-spinning have been investigated by transmission electron microscopy (TEM), and three dimensional atom probe (3DAP). The as-cast 2 mm diameter rod sample contained Cu-rich nanocrystals in the amorphous matrix, while the melt-spun ribbon was fully amorphous. The composition of the Cu-rich nanocrystals was around Cu 76 Zr 19 Ti 5 with the fcc structure (lattice parameter a ¼ 0:37 nm), which is a metastable Cu phase supersaturated with Zr and Ti. Annealing the as-cast rod at 713 K (T g ) for 10 min led to a decrease in compressive plastic strain from 1.8 to 0.6% accompanied by an increase in the volume fraction of the Cu-rich crystal.

“…Subsequently, we have also found that the homogeneous dispersion of fccAl or hcp-Mg nanoparticles with grain size of 5 to 10 nm into Al-and Mg-based amorphous phases causes a further significant increase in tensile strength to 1560 MPa for Al-based alloy 6) and 1000 MPa for Mg-based alloy. 7) This paper intends to review our recent results on the developments of Al-and Mg-based nonequilibrium bulk alloys with good mechanical properties produced by the warm extrusion process of rapidly solidified alloy powders.…”

The stabilization of supercooled metallic liquid occurs for a number of alloys where the constituent elements have the following three rules, i.e., multi-component of more than three elements, significant mismatches of atomic size above 12% among the main three elements, and negative heats of mixing among their main elements. The use of the stabilized supercooled liquid has enabled us to synthesize a number of novel advanced metallic materials. In this review, we present the alloy components, fabrication processings, structures, mechanical properties and applications of high-strength Al-and Mg-based alloys with glassy, nanocrystalline or nanoquasicrystalline phase which were developed on the basis of the concept of the utilization of stabilized supercooled liquid for the last one decade.
