Lattice Parameters of Metastable Silver-Copper Alloys

Early Stages of Crystallization in Phase-Separated Amorphous Copper-Niobium Alloy Thin Films

“…[1] Interestingly, in recent years, there have been a number of reports of amorphous phase formation in immiscible systems with a large positive enthalpy of mixing in both the liquid and solid phases. Examples of such immiscible systems forming amorphous phases include Ag-Ni, [2,3] Cu-Nb, [4] Ag-Cu, [5,6] Ag-Fe, [8] Ag-Gd, [9] Cu-Ta, [10] and Cu-W. [10] In such immiscible systems, the mixing of the constituent elements even in the liquid state is highly unfavorable and results in a substantial increase in the Gibbs free energy of the system. Therefore, the rationale behind the formation of amorphous phases in such immiscible systems on rapid quenching is not well understood.…”

W–Sn solid solution synthesized by mechanical alloying at room temperature

“…Li). ricated by liquid quenching technology very early last century [15,16]. However, the melting point of tungsten is as high as 3407 • C, while the boiling point of tin is 2603 • C. So it is hard to produce W-Sn alloy by conventional melting and quenching method and no experimental information about W-Sn system has been presented so far.…”

The Way from Today's Materials to New Kinds of Amorphous Solids: Nano-glasses

“…One of the most widely used implantable metals, titanium and its alloys have attracted considerable scientific and technological interest due to the intrinsic bioactivity, the high resistance to wear and to corrosion resistance of Ti as well as of many Ti alloys. Thus, substantial efforts were devoted to the development of biocompatible Ti-based bulk metallic glasses (BMGs) (Linde 1966;Ma 2003;Hauser 1975;Nastasi et al 1985). However, without Ni -which is toxic to the human body -Ti-based alloys generally exhibit a lower glass-forming ability (Oak et al 2007;Morrison et al 2007, Qin et al 2007) than the other metal-based BMGs, for example, Zr-based, Cu-based or Fe-based alloys.…”
