The following are links to other organisations that the Thermodynamics and Process Modelling Group works with.


SGTE - a consortium of centres engaged in the development of thermodynamic databanks for inorganic and metallurgical systems and their application to practical problems. NPL is a founding member of SGTE. It's aims are the provision, maintenance and expansion of high quality databases, that enable the user to undertake complex calculations of chemical equilibrium efficiently and reliably and also to enable cooperation in a broader international effort to unify thermodynamic data and assessment methods.


MIRO - The Mineral Industry Research Organisation
We have worked with MIRO for a number of years, currently in relation to the Oxide and Aqueous projects.


CALPHAD- Computer Calculation of Phase Diagrams
The organisation that publishes the CALPHAD Journal and organises the annual CALPHAD Conference.

MAP Logo

MAP - Materials Algorithm Project
The Materials Algorithms Project serves as a centre for the "validation" and distribution of algorithms of use in the modelling of materials. MAP consists of a perpetual library of programs and data, which with skill and imagination can be exploited to develop new concepts by building on existing knowledge.

NIST Phase Diagram Center

The NIST Metallurgy Division has long played a major role in the generation, evaluation and use of alloy phase diagrams. Between 1982 and 1990, an international effort to evaluate binary phase diagrams was coordinated by the Metallurgy Division and ASM. In recent years, effort has focussed on some specific families of alloys, including nickel-based superalloys for aerospace applications and high-temperature and lead-free solders.


The main objective of Action 531 is to increase the basic knowledge on possible alloy systems that can be used as lead-free solder materials and to provide a scientific basis for a decision which of these materials to use for different soldering purposes in order to replace the currently used lead-containing solders in the future.


The focus of the COST Action is the investigation of Pb-free replacements for high-Pb solders for high-temperature applications. This comprises a study of the chemical, physical and mechanical properties of alloys containing a large number of permutations of different alloying elements. A multiscale approach will be used:


COST535The main objective is to create the thermodynamic platform which is crucial for the development of new alloys based on intermetallic compounds. This scientific platform will comprise models of the thermodynamic properties of engineering aluminides, evaluated existing data and data, based on new theoretical and experimental approaches.

Phase Transformations & Complex
Properties Research Group

The Phase Transformations & Complex Properties Research Group in Cambridge University attempts to predict changes transformations ie the arrangement of atoms in a solid, and their consequences in the hope of creating novel alloys and processes. The properties of materials depend on parameters such as the composition, stress, temperature and magnetic field and the group carried out research to model such behaviour.

Innovative Electronics Manufacturing Research Centre

The mission of the Innovative electronics Manufacturing Research Centre (IeMRC) at Loughborough University is to establish a centre of expertise through which UK industry can access and influence research in electronics manufacturing.

Institute for Materials Research, University of Leeds

Institute for Materials Research, Leeds UniversityTo undertake internationally leading research and postgraduate training in selected fields in materials science and engineering, serving the future emerging needs of industry and society.


Institute of Materials, Minerals and Mining - Materials Chemistry CommitteeThe aim of the Materials Chemistry Committee is to provide UK industry and research bodies with access to reliable and up-to-date information for phase equilibria and the thermodynamics for all classes of engineering materials. Such information plays a vital role in under-pinning many spheres of materials science and technology. With this in mind the committee seeks to coordinate and monitor critical assessment and experimental work in various organisations and institutions in the UK, to avoid undue overlap of experimental studies and to encourage and nurture international co-operation on phase diagram knowledge.


APDIC aims to meet the needs of the world wide technical community by coordination of the overall objectives for membersí programs and publications, the establishment of assessment priorities, the coordination of activities among members to reduce duplication of effort, to promote quality standards for phase diagram evaluations, to assist effective dissemination of data, to promote the application of phase diagrams in industry and academia and to advance the evaluation and assessment programs world wide .
