This example demonstrates how to create a phase diagram for Al-Cu containing both stable and meta-stable phases. The technically relevant composition range up to 10% Cu is covered in the simulations. Using this phase diagram, information on the nucleation characteristics and precipitation sequences of meta-stable phases can be gained.

The aluminum - Al2Cu phase diagram; i.e. the part left to the 53 at% Cu, is about as simple as you can have it for two atoms that cannot mix atomically at any large ratio. It has the same structure as the lead-tin "solder" phase diagram we looked at before. Phase diagram Al - Cu The intermetallic compound Al2Cu at 53 at% Cu is called the Θ phase.

Use the Al-Cu phase diagram and design the fabrication procedure for the alloy. Solution: The specimen must be heated up to T. 0 ~ 540 °C in the α-phase region and then quenched to room temperature. Then the sample must be cold worked to reach the desired shape. After cold

This information is used to build the Al-rich region of the Al-Cu phase diagram, which is compared with the limited experimental data available in the literature for the metastable phases. In addition, the thermodynamics of the Guinier-Preston (GP) zones at the early stage of phase separation is also analyzed.

The equilibrium mixture, according to the phase diagram, would be 93 % α + 7 % CuAl 2, and the α phase contains at most 0.1 % Cu. The quenched solution thus contains 40 times more dissolved Cu than required for equilibrium. There is thus a large driving force for precipitation, and nucleation starts quickly, homogeneously, and in many places.

2.12.2021 · According to the Al-Cu phase diagram, after solution treatment at 538 °C, the Al 2 Cu phase will be in equilibrium with the matrix , meaning that the particles observed in fracture surfaces were coarse Al 2 Cu particles that exist in all specimens.

The Al-Cu phase diagram shows that holding a 4.5% alloy at 515 to 50ºF will cause all the copper to go5 completely into solution. This is the typically know as the “solution heat treating temperature”. If the alloy is slowly cooled, then the equilibrium structure of Al + CuAl 2 will form. The CuAl 2 that forms is large,coarse and incoherent.
