Thermal expansion coefficients of Cu-Zn alloy, nickel and iron around the critical temperatures (structural or magnetic order-disorder transition) were measured by a push-rod type dilatometer (DIL) using modulated temperature profile. The temperature correction procedures were established from the experimental conditions measured at many frequencies. As a result, a multi-frequency temperature-modulated dilatometric experiment was established.
