Structural evolution of a glassy monoatomic Ta film during heating

In order to unravel mechanism of glass transition and crystallization of metallic glass, we propose to perform in-situ heating PDF tests of monoatomic glassy Ta film which was developed by us recently. The reason is that, by using monoatomic metallic glass, coordination number and bonding length can be calculated, and the partial PDF problem will be totally avoided, and the crystallization product will be single phase which make Rietveld refinement possible. Based on such experimental data, we think that we will establish physical theory of glass transition and crystallization of metallic glass.
