The strain sensitivity coefficients of resistance of rhodium, iridium and Pd20Ag80

The elastic and plastic strain sensitivity coefficients of resistance of rhodium, iridium and the Pd₂₀Ag₈₀ alloy are measured under various annealing and cold- or hot-working conditions. The experimental results are consistent with the theoretical predictions. This work has verified the theory presented in a previous paper. The three-dimensional effective electronic number should be used in the calculation of the elastic strain sensitive coefficient of resistance. In case plastic deformation occurs, the effects on the strain sensitivity coefficient of resistance by elastic deformation diminish and a different formula for plastic deformation should be employed.
