The linear thermal expansion of the bulk amorphous Zr{sub 41.2}Ti{sub 13.8}Cu{sub 12.5}Ni{sub 10}Be{sub 22.5} (atomic percent) alloy has been measured from 80 K to 773 K. The data for {ital T}{lt}{ital T}{sub {ital g}} were fitted by a model based on the Gr{umlt u}neisen relation and a Debye expression for the heat capacity. From the fit, we deduced the Gr{umlt u}neisen parameter, {gamma}=1.25, and the Debye temperature, {Theta}{sub D}=400 K. Annealing the amorphous alloy at 663 K, which is between the glass transition temperature {ital T}{sub {ital g}}=623 K and the crystallization temperature {ital T}{sub {ital x}}=693 K, causes viscous flow in the sample. This is due to the small viscosity in the undercooled liquid. {copyright} {ital 1996 Materials Research Society.}
