Apr 29, 2014 · A low-temperature Au-Al-Cu phase diagram could provide essential information to understand the reactions between the Au-Cu alloy wire and the Al pad. The stability of intermetallic phases is closely related to the reliability of wire bonding [1, 2]. A β (Au 7 Al 4 Cu 5) phase exhibiting martensite-like properties was developed [3–5]. The embossed and fine-layered surface of this material, which originates from a martensitic transformation, exhibits a characteristic shining color and is ... phase diagram of the system, Figure 1203.01.02. Note that, apart from the pure elements, all alloys of Cu and Ni have a range of temperatures over which solidification (freezing) occurs - the field is defined by the liquidus and solidus lines on the phase diagram. We now need to look more closely at the consequences of this. The calculated isothermal sections of the Cu Ag Au ternary phase diagram show complex two- and three-phase equilibria between disordered and ordered phases; the three-phase equilibria, although expected, have not been reported in experimentally determined phase diagrams.
