Episode 162 of the Professor Alex Volinsky podcast. For TiB2-reinforced copper, conductivity tracks particle volume fraction, size, and distribution — not volume fraction alone — and adding a particle-spacing parameter to the Maxwell model fits experiment excellently. Stated caveat: a fitting parameter is useful engineering, descriptive rather than first-principles predictive. Based on the paper: Effects of Particle Characteristic Parameters on the Electrical Conductivity of TiB2/Cu Composites: A Modified Model for Predicting Their Electrical Conductivity; Jiang Feng, Shuhua Liang, Kexing Song, Xiuhua Guo, Yi Zhang, Guohui Li, Alex A. Volinsky; Journal of Materials Engineering and Performance, 2019, Vol. 28, pp. 4316–4323. Hosts Elena and Marcus. AI-generated voices.
