Recently, two-phase amorphous alloys have been obtained through liquid phase separation in La-Zr-Al-Ni-Cu[1], Y-Ti-Al-Co[2], and Ni-Nb-Y[3] by means of rapid solidification. In a multi-component alloy system, phase separation in a liquid state occurs first, after which each liquid region undergoes a liquid-to-glass transition, resulting in the formation of a two-phase amorphous alloy. These alloys systems also show an unique behavior of "multi-step liquid phase separation". Figure 1 shows the schematic illustration of multi-step liquid phase separation. We try to develop new metallic materials based on the concept of multi-step liquid phase separation in Fe-Cu and Co-Cu based alloys [4,5]. Figure 2 shows the typical example of Fractal-like structure formed by multi-step liquid phase separation in Fe-Zr-B-Cu alloys [4,5].

Ti-Ag 合金は、状態図において平滑な液相線を示すことが大きな特徴です。Ti-Ag合金は、液体超急冷によって液体分離の発現にともなう特徴的な組織をしめすともに、金属間化合物の形成が抑制されます。Ti-Ag系合金における液体分離現象の発現と特異な凝固組織の形成は、Ti-Nb-Ag合金でも見られます。

''Macroscopically phase separated melt-spun ribbon. Continuous rapidly solidified ribbon shows Co-Si-B amorphous / Cu crystal dual layer structure [1,2]''
~
~

We firstly develop a dual-layer ribbon by conventional single-roller melt-spinning method [1,2]. In Co-Cu-Si-B melt-spun ribbon, the roll-side surface comprised Co-Si-B-based amorphous phase with Cu crystalline nanoscale globules, while the free surface showed a thin crystalline Cu layer. A macroscopically separated unique structure was obtained by the simultaneous occurrence of liquid phase separation of the Co-Cu-based alloy system and amorphous phase formation in the Co-Si-B alloy layer.~

We firstly develop a rapidly solidified Fe-Cu-Si-B alloy with a macroscopically separated structure by the arc-melt-type melt-extraction method [1]. A unique core-wire/surface-cover-layer structure composed of core Fe-Si-B-based amorphous alloy and cover Cu crystal was formed by liquid phase separation during rapid quenching of thermal melt.~
