The thermal expansion of non-crystalline Zr65Al7.5Cu17.5
Ni10 has been studied in the range of
the glass transition and in the undercooled liquid using a dilatometric device.
The measuring technique used permits reliable experimental results up to 40 K
above the glass transition temperature. The linear thermal expansion coefficient
obtained is almost constant in the glassy state with a value of
. It discontinuously increases at the glass transition
temperature yielding a value of 
in the undercooled
liquid. The results are compared with specific heat measurements of the amorphous
material in this temperature range and are interpreted in the framework of a cluster
model.
