The influence of hydrogen on the short-range order of Zr[sub 60]Ti[sub 2]Cu[sub 20]Al[sub 10]Ni[sub 8] bulk metallic glass has been investigated. Interstitial solution of hydrogen up to a hydrogen-to-metal ratio of H/M=0.43 was reached in 1 mm thick bulk samples by slow electrochemical charging. Preferred occupation of interstitial sites of polyhedra formed by Zr atoms is observed. The atomic distances of higher coordination shells expand with hydrogen analogously to the macroscopic volume expansion. © 2003 American Institute of Physics.
