Cyclic loading behavior of micro-sized polycrystalline copper wires

Under a Creative Commons license


Micro-sized polycrystalline copper wires of diameters ranging from 5 μm to 36 μm were cyclically loaded under stress-control in many steps with increasing the applied stress amplitude after a saturation state in plastic strain is reached. It is observed that the thicker wires show smaller plastic strain at saturation as well as smaller creep strain compared to the thinner wires. The results were discussed combined with the monotonic tensile results of these micro-sized wires.
