TCCU: TCS Cu-based Alloys Database Revision History

Software release 2024a (December 2023/January 2024)

• Corrected the default setting of major components in BCC, FCC, and HCP phases.
• Updated the surface tension of the Fe-Ni system.

Software release version: 2023b Update 1 (September 2023)

Software release version: 2023a (December 2022/January 2023)

• Corrected an error in the molar volume of the B2 phase in the Al-Fe-Ni system.

Software release version: 2022b (June 2022)

• Two new elements: Ce and La.
• 13 new binary systems: Cr-O, Cu-La, Cu-Ce, Cr-La, La-Zr, La-Ni, Ce-La, Al-Ce, Ni-Ce, Nb-Ni, Nb-Ti, Ni-Ti, Zr-O.

Revised description of liquid in Al-Cu-O system

Software release version: 2019b (June 2019)

• Addition of Ge.
• Ten Ge-X (X=Ag, Al, Au, Co, Cr, Cu, Ni, Sn, Ti, Zr) binary systems are added.
• Two ternary systems Ag-Cu-Ge and Au-Cu-Ge are included.
• Volume data for the newly added phases are assessed or estimated.

Software release version: 2017a (March 2017)

Volume data, including molar volume and thermal expansion, for most of the solution phases and intermetallic phases have been added in TCCU2. This allows for the calculations of volume fraction of phases, density, thermal expansion and lattice parameters etc.

Two elements, Mo and O, have been added in TCCU2. The thermodynamic assessments of the Ag-P, Al-O, Co-Cr, Co-Nb, Cr-Mo, Cr-Nb, Cu-Mo, Cu-O, Fe-Mo and Mo-Ni binary systems have been implemented. The following ternary systems have also been assessed: Ag-P-Sn, Al-Cu-O, Co-Cu-Nb, Co-Cr-Cu, Cr-Cu-Nb, Cr-Cu-Mo, Cu-Fe-Mo and Cu-Mo-Ni. Additionally, the Cu-P, Co-Pb, P-Zn and Cu-P-Sn descriptions have been updated.
