“…A large amount of engineering applications, like railway equipment, marine hardware or lead frames, requires materials that exhibit high mechanical strength as well as good electrical and thermal conductivities. In that way, copper alloys are widely used although the enhancement of mechanical properties usually comes along with a decrease of the electrical performances [1,2]. To face this problem, oxide-dispersion-strengthened (ODS) copper alloys, where aluminium oxide nanoparticles are dispersed in the matrix, is one of the existing solutions [3][4][5].…”

Low cycle fatigue tests were performed at room temperature to investigate the role of the microstructure of a Cu-Ni-Si alloy on the stress response to strain cycling and on the fatigue resistance. The cyclic accommodation consisted in a hardening followed by a softening. TEM analysis showed that in some grains dislocations remained isolated and confined between precipitates while in other grains dislocations piled up at δ-Ni 2 Si precipitates and then cut them. Repetitive cutting allows their dissolution and formation of precipitate-free bands where the plastic deformation is localised. The Manson-Coffin diagram exhibited two regimes according to the proportion of grains involved in the plastic deformation accommodation.

“…To overcome this aspect, precipitation hardened copper alloys have been developed, such as copper-beryllium alloys. Those latter exhibits a good balance between mechanical, thermal and electrical properties [1,6]. But due to the price and the toxicity of beryllium and its compounds, alternative copper alloys have been formulated.…”

In this study, Cu-TiC nanocomposites were fabricated from a mixture of Cu and 5÷15% wt. TiC powders by ball milling and subsequent spark-plasma sintering. The morphology of Cu-TiC nanocomposite powders were observed by field emission scanning electron microscopy. Only characteristic peaks of Cu and TiC phases were detected from X-ray diffraction patterns of milled powder mixture. Sintered compacts showed a highly densified compacts (∼95% relative density) while retaining fine grains in the matrix. The hardness, wear resistance, and fracture surface of the sintered specimens were also investigated.
