An Example using the COST 507 Database Here an example using data from "Leading System 1 is given. The quinary system Al- Fe-Mg-Mn-Si is important to the aluminium industry since it encompasses the 1000, 3000 and 5000 series wrought alloys. These cover, eg, major products including lithographic sheet, UBC's (universal beverage cans) body and can end material, and material for automotive applications (body panels, space frames etc). Figs 1-3 show calculated proportions of the phases present as a function of temperature for an "idealised" 5000 series alloy, and demonstrate the power of the existing database. To determine such information by experiment, whilst crucial in specific test cases, would be prohibitively expensive and time-consuming. Such information is not only of relevance to the development and improvement of the above products, but also to their recycling. Thus the database, still under continuing development and improvement, and currently including 78 binary and some 25 ternary datasets (in addition to the ternary assessments from Coordination Group B) is "up and running". Concluding Remarks During the Vaals Workshop quotations in relation to the use of the thermodynamic database were kindly provided on behalf of Alean International Ltd and Rolls-Royce pic. The former is reproduced here, together with an update of the latter: Please refer to Figs 4 and 5. "The COST 507 database for aluminium alloys has been widely used in model alloy work: knowledge of equilibrium conditions is a prerequisite for kinetic analyses of solidification, homogenisation and annealing. The final quinary database will be an invaluable tool for the European aluminium industry, applicable to alloy design and optimisation, process modelling and efforts to improve recyclability through increasing iron and silicon tolerance." Dr Ρ V Evans Alean International Ltd, Banbury Laboratory Please refer to Fig 6. "Titanium aluminides based on the TiAl phase are a relatively new class of lightweight high temperature materials that will find application in the gas turbine in the near future. The 1st generation alloys were based on Ti - 48 at% Al with additions of 2 - 4 at% transition metals. However the alloy chemistry was not optimised for gas turbine applications and the chemistry microstructure relationships were poorly understood. The titanium aluminide data from COST 507 has been used and extended by Rolls- Royce to assist in solving and understanding these problems. This has enabled a viable production process for small components to be identified and initial production for testing in advanced engine demonstrators is underway". Rolls-royce pic 19
