Zusammenfassung: | Copper alloys have many properties, which make them suitable in wide-ranging
applications in all the engineering industries. For the investigated alloys the most important
properties are hardness, strength and electrical conductivity. Precipitation hardenable alloys were
studied by Jominy end-quench test, in order to examine the change of hardness, electrical
conductivity and microstructure as a length of the test bar (i.e. cooling rate). In the first step samples
were solution treated at different temperatures, then water quenched followed by aging. Cold-work
after quench was applied in some alloys and improve in the properties was clearly seen. The
following Cu-alloys were investigated: Cu-Co-Ni-Be, Cu-2Be-Ni and Cu-2Ni-Be. |
