Abstract

The temperature dependence of the strength of a thin copper electrodeposit has been measured from room temperature to 150 °C by microtensile testing. The ultimate tensile strength decreased from around 240 MPa at room temperature to just above 200 MPa at 150 °C. The yield strength followed a similar trend. Elongation to failure increased slightly with temperature. The Young's modulus, as measured by the unload-load slope, was well below the values expected based on averaging single- crystal elastic constants at all test temperatures. The strain rate effect on strength at room temperature, using a range of over a decade, was low, with a weak trend upward.
