Thermal expansion of Al3Sc and Al3(Sc0:75X0:25)

  title={Thermal expansion of Al3Sc and Al3(Sc0:75X0:25)},
  author={Yoshihisa Harada and David C. Dunand},
The thermal expansion coefficient of Al3Sc and Al3(Sc0:75X0:25), where X is Ti, Y, Zr or Hf, was measured by dilatometry between 25 and 1000 C. The measured value, ð16 1Þ 10 6 K , is constant between 25 and 900 C and insensitive to alloying element. Good agreement is found with a literature value determined from first-principle cal-
