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.

Pe r/Romania mentalitatea asta e privită cu umor și sarcasm. Dar am citit niste comentarii la unele știri (mai ales din Cluj) cu mențiuni precum "aia nu sunt clujeni", "toate viniturile" etc. Și care se luau mult prea in serios. Oamenii ăștia realizează cat de mult au contribuit "viniturile" la dezvoltarea orașului lor "strămoșesc"? Că fără ei, și nu mă refer doar la Cluj, s-ar fi făcut resimțite consecințele sporului natural negativ și a emigrării masive din Romania? Există două feluri de or...
The portion of the Cu–Ti equilibrium diagram in Fig. 1b indicates a polymorphic transformation of the Cu 4 Ti phase; it suggests that the tetragonal D1 a phase is the stable phase below ≈ 500°C and that the orthorhombic Au 4 Zr-type structure is the equilibrium high temperature phase.
