Question:

The electrical resistivity of a beryllium alloy containing 5 at% of an alloying element is found to be 50 x 10-6 ohm · cm at 400° C. Determine the contributions to resistivity due to temperature and due to impurities by finding the expected resistivity of pure beryllium at 400°C, the resistivity due to impurities, and the defect resistivity coefficient. What would be the electrical resistivity if the beryllium contained 10 at% of the alloying element at 200°C?
