Abstract
A fast X-ray diffraction apparatus has been developed for obtaining the local structures of bulk metallic glasses at the supercooled liquid state by applying the Debye-Scherrer camera geometry in combination with a curved position sensitive proportional counter. This arrangement makes it possible to eliminate the time loss due to angular motion of a counter and to do a very short time X-ray measurement when using the conventional in-house X-ray source. The usefulness of this new apparatus was confirmed by obtaining the radial distribution functions of silicon powder and SiO2 glass sample within one hundred seconds. Then, the short-range ordering structure of the supercooled liquid Pd40Ni10Cu30P20 alloy was observed as a function of time at 583 K.
