MethodologyMethodology
Choose unary data– SGTE unary database v4.4
Search for binary data– SGTE/NPL solders database– Brno solders database– Literature– Data generated by COST 531
Test for consistency/compatibility– MTDATA– ThermoCalc– Pandat
Creation of consistent TDCreation of consistent TD
The Gibbs energy descriptions included in the database should be unique, based on the same assumptions, conditions and models.
A reliable thermodynamic database has to be consistent with respect to:
1. models used for the expression of Gibbs energy functions in the system
2. models and names used for the description of phases, included in the system
3. thermodynamic data used for the same elements and compounds in different systems, starting with unary data for stable and unstable crystallographic structures for all elements, included in the database.

Workgroup “kick-off” meeting
Held in BRNOeither end of August or September
Participants – anybody involved
Program:
•Plenary lectures from “experts”•Round robin discussions – WG separately, the overall discussion at the end of the
session •Presentation of ideas and plans by WG and database coordinators•Presentation of Group project (by the leaders) both prepared and planned – actualized with respect to previous discussion results.
Aim: Plan and coordinate the work on systems and methodology as much as possible, preparation of much detailed working plans for WGs
This work was supported by the COST projects This work was supported by the COST projects Nos. OC 531.001 and OC 531.002 of Ministry of Nos. OC 531.001 and OC 531.002 of Ministry of

‣ … and the benefits ?
At the end of the COST Action, a wide set of data will be available for different solder alloys.
Number of environmentally friendly lead-free solder systems for high-temperature applications that exhibit properties suitable for industrial use and which can be taken into further consideration as replacements for the existing high-lead solders.
The present Action will also provide the opportunity for Academic Institutions to coordinate their research efforts on a European level with industry - SME and large companies are involved either directly (Cookson Electronic, Next Experience B.V., Mat-Tech, B.V.) or through cooperating partners (PHILIPS, etc.)
It will contribute to the strong position of the Universities and Research Institutions involved in the field of materials science. This will make these academic institutions more attractive for industrial (commercial) partners oriented towards sustainable technologies and maintain the education standard of European students at a high level

Creation of consistent TD – cond. 1Creation of consistent TD – cond. 1
Selection of models for the description of a particular phase and allocation of a name to it.
Cu6Sn5 and CuIn - phases
in the ternary Cu-In-Sn system - complete solubility was found experimentally between the phases, which were not deemed to be identical from the crystallographic point of view when the theoretical assessments of relevant binary systems were prepared by various authors.
The same systems were often modelled several times by various authors – identification of models used in these assessments, number of sublattices, sublattice ratios, etc.
Creation of consistent TD – cond. 2Creation of consistent TD – cond. 2
Consistency of the assessment of the Gibbs energy for an element or compound in a given crystallographic structure (specie) in various subsystems in the database, containing this specie.
Especially the Gibbs energy assessment for the metastable crystallographic structures may differ significantly
the parameters are either estimated (in the past) modelled during the assessment of higher order system, where such structure
exists the energy difference of such hypothetical phase at 0K with respect to stable
phases is calculated by ab-initio methods.
