HISOLD - Advanced Solder Materials for High Temperature Application

Anotace
Investigator RNDr. Aleš Kroupa, CSc. is the Chair of Management Committee of the whole project.
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 is used:
meso-scale: The application of thermodynamics and kinetics to the study of alloying behaviour; the development of materials property databases.
macro-scale: The creation of a phenomenological description of corrosion and deformation processes occurring in a solder joint during fabrication and service,
micro- (nano-) scale: The investigation by experiment and modelling of the initial stage of the formation of intermetallic phases at the solder/substrate interface.
This is efficiently achieved through coordinated international cooperation providing a basis for interdisciplinary research. The action increases the basic understanding of alloys that can be used as Pb-free alternatives to high-temperature solders for practical applications, for example in the aerospace and automotive industries.
