ELECTRON PROBE MICROANALYSIS AS ONE TOOL FOR PHASE DIAGRAM INVESTIGATION

摘要

The need to develop high temperature materials leads also to the need of improving and developing new solder/brazing alloys. The understanding of interface reactions during the joining is fundamental for industry and also for science. Intermetallic materials is one example of attractive structural and functional materials with many interesting properties like high-temperature strength, shape-memory effect, large hydrogen storage, and high magnetisation. The lack of phase diagram information and joining/repairing brazing alloys is often the drawback for the applications of these intermetallic alloys. To facilitate a more efficient alloy design as well development of joining technologies of these intermetallic alloys it is necessary to obtain quantitative information about phase equilibrium, stability and phase relations.
