There was not only a diffractive ring composed of the crystal diffraction spots but also a diffused halo ring was found. It indicated that there was an amorphous phase in the Al–Cu interface transition zone.A two-phase layer (AlCu + ε) was in contact with the Al 2 Cu phase layer; therefore, the Al 2 Cu-ε-AlCu three-phase equilibrium was generated. The existence of this three-phase equilibrium was confirmed through the alloy sample A1 and the equilibrium microstructure (Fig. 4).Company AlCu Niš – obojeni materiali has been established in Serbia. We cooperate closely with our strategic partners from the neighbouring Italy and Croatia. In 2012, we established company AlCu d.o.o. in Sarajevo, Bosnia and Herzegovina.

In the face of these egregious civil liberties abuses, a small group of people decided to take a stand, and thus was born the American Civil Liberties Union. The ACLU has evolved in the years since from this small group of idealists into the nation’s premier defender of the rights enshrined in the U.S. Constitution.

The solute segregation energy can be described by comparing the total energiess as shown in Eq. (1): (1) Δ E seg = E (Al x) − E (Al b), where E represents the total energy obtained from first-principles DFT supercell calculations. A sharp interface model within the context of DFT is appropriate to simulate the interface between Al and θ′-Al 2 …

The last one with composition of AlCu is known to exist in two stable forms: the high temperature phase η 1 (oS32) [14] stable between 847 and 898 K, and the low temperature phase η 2 (C2/m) [22] stable below 854 K. For simplicity, no separation of those phases was considered and hence those phases were modeled as γ, ε, ζ and η in this work.

Following blanket metal film deposition, the wafers were annealed in air in a Plexus F2300 thin film stress measuring apparatus. All isothermal anneals were performed at 450 for 20 min. Wafers were …The results indicate that the light grey region with no obvious boundary is composed of AlCu and Al4Cu9 phases. The phases can be further affirmed by EPMA of four different positions (P1−P4 in Fig. 2(d)) that there are AlCu and Al4Cu9 Cu-rich phases from Al matrix to Cu, which is consistent with the previous studies [17,23,25].In the thermodynamic description of the Al-Cu series by Kaufman et al. [4], four intermediate phases were considered, θ (Al 2 Cu), η 2 (AlCu), γ 1 (Al 4 Cu 9), and β (BCC), of which β phase is only above 873 K appear. Then Chen et al. [5] introduced two other random phases, δ and α 2 phases, into the thermodynamic model. Won et al.
