Abstract

The thermal expansion coefficient of Al₃Sc and Al₃(Sc_0.75X_0.25), where X is Ti, Y, Zr or Hf, was measured by dilatometry between 25 and 1000 °C. The measured value, (16±1) × 10^-6 K^-1, is constant between 25 and 900 °C and insensitive to alloying element. Good agreement is found with a literature value determined from first-principle calculations.
