Original abstract

Ag nanopowders were prepared as potential low-toxic constituents of novel solders by a chemical wet synthesis. Resulting nanoparticles were characterized using a transmission electron microscope. Model joints, i.e. sandwiches consisting of thin copper plates with Ag nanopowder interlayer were prepared and annealed at various temperatures. Metallographic cross-sections were studied using a scanning electron microscope. The main emphasis was placed on the characterization of sintered Ag layers on crosssections by means of nanoindentation experiments. Microhardness and other mechanical properties of sintered Ag layers were measured by instrumented indentation with Berkovich indenter. Both the mechanical properties and the observed microstructure were compared with our previous results obtained on similar materials.

Pomocí mokré chemické syntézy byly připraveny nanoprášky Ag jako potenciální konstituenty netoxických pájek. Vzniklé nanočástice byly charakterizovány pomocí transmisní elektronové mikroskopie. Byly připraveny modelové spoje, sestávající z tenkých destiček Cu s mezivrstvou Ag nanočástic, a tyto byly žíhány za různých teplot.
