At the Vaals Workshop this presentation was made primarily using a series of colour
OHP's summarising work progress during the course of the Action on a fairly personal
basis, as a tribute to the scientists (mainly present at the meeting) who have contributed
to the work over the years. A written summary of this is not possible. Here, a brief
history of COST 507 is presented, together with a summary of the results achieved. For
those not wishing to read the details, please refer to the Concluding Remarks - "the
proof of the pudding is in the eating".
Origins of COST 507
It is more than appropriate that this Final Workshop for the COST 507 project should
take place in Vaals, a few kilometres from the Rheinisch Westfälische Technische
Hochschule Aachen. The Action began, in its infancy, as a BRITE-EURAM Project
Proposal, submitted by Philip Spencer, RWTH, on behalf of SGTE (Scientific Group
Thermodata Europe) in 1986, Philip at the time living in Vaals. This proposal, at the
suggestion of the COST Secretariat, led to COST 507 Round I, the original
Memorandum of Understanding signed 8th December 1988 on behalf of Germany,
Greece, France, Norway and United Kingdom. The project initially involved 14
signatory countries: A, B, CH, D, E, F, GR, I, N, NL, P, S, SF, and UK, indeed, most
of the signatory countries at the time, and the Baikov Institute of Metallurgy, Moscow,
joined during Round I.
The project was given the formal, rather cumbersome, title "Measurement and
Evaluation of Thermochemical and Thermophysical Properties to Provide a Database
for the Development of New Light Alloys", normally abbreviated to "A Database for
Light Alloys".
Summary of Objectives:
The principle objective of this project has been to provide a computerised
thermodynamic database to permit the calculation of multicomponent phase equilibria
for light alloys based on aluminium, magnesium and titanium, to aid materials
scientists and engineers in the development and successful utilisation of a wide range
of commercial light alloys. Experimental studies, required to provide missing
information, critical assessment of ternary alloy phase diagrams and the acquisition of
thermophysical properties have been included.
