COST MP 0602 Action

• Ales Kroupa - Expression of Interest
• Phase equilibria in Zn-Sn-X metallic systems for
  high-temperature lead-free solders
• Institute of Physics of Materials, Academy of
  Sciences of the Czech Republic
• Members of the team
• RNDr. Milan Svoboda, CSc., RNDr. Jiri Bursik,
  CSc., ing. Adela Zemanova, PhD.
•  
• The aim of this project
• to study the systems on the Zn-Sn base, from
  the point of view of the thermodynamic
  properties and phase equilibrium diagram
  assessments (WG 1).
• These results will serve as a background for
  evaluation of other physical and mechanical
  properties of prospective high-temperature
  solders.
• The study will cover materials convenient for
  soldering in the temperature range 230-350 C.
• Most activities will deal with the metal systems
  not included in the previous COST 531 database.
• The basic system can be characterised as Sn-Zn-X
  (X Al, Mg, Ni, Pd, Sb). The concrete selection
  of alloying elements will be done on the basis of
  cooperation with other research groups involved
  in the COST MP0602 Action.
• The systems will be studied experimentally and
  theoretically, main aim being to assess reliable
  and correct phase diagram of above mentioned
  systems.

• Resources available in laboratory of proposer
• Experimental part
• TEM/STEM Philips CM 12 equipped with EDAX
  Phoenix).
• SEM JEOL JSM-6460 with the energy and wave
  dispersive microanalysers of X-rays - EDX, WDX,
  and electron backscattered diffraction EBSD
  INCA Energy, Wave and Crystal).
• DSC/DTA apparatus Netzsch DSC 404C, equipped with
  high temperature furnace, allowing to study phase
  transformations up to 1600 C.
• The X-ray diffractometer Philips Xpert will be
  also used for the identification of phases,
  coexisting in samples.
•  Theoretical part
• COST 531 database
• The MTDATA and THERMOCALC software for
  assessment of phase diagrams
• The software for the ab-initio calculations is
  also available in collaborative laboratory.
• A. Kroupa , Adela Zemanova - thermodynamics of
  metals and phase diagrams modelling. They have
  broad experience in the theoretical modelling of
  secondary phases in multi-component thermodynamic
  equilibria.
• M. Svoboda and J. Burík are specialised in the
  field of  analytical electron microscopy (AEM).
  They investigated systematically modern
  multicomponent and multiphase materials,
  including promising materials for classical
  lead-free soldering, especially from the point of
  view of identification of intermetallic phases
  and their influence on material properties.

Hopeful partners J. Vrestal, A. Dinsdale, A.
Watson, H. Ipser, L. Zabdyr .. Skills or
expertise sought from other partners   The
research group welcome a cooperation with any
research team, which can supply data for the
assessment of phase diagrams, especially the
thermodynamic data, which are crucial for the
correct assessment. The teams measuring further
physical and materials properties are also very
important as they can complete the database of
knowledge of above mentioned systems.
