Pulsed Laser-Induced Melting of Intermediate Cu-Zn Phases [pdf]Paper  abstract   bibtex   
We have discovered that the # and-y brasses of Cu-Zn exhibit clearly resolved increases in reflectance upon melting with a 30 ns ruby laser, which allow their melt durations to be readily measured. This system thus offers potential for obtaining quantitative information about the solidification kinetics of metals. We have also found that a heteroepitaxial layer of f,' brass is formed on the surface of (ordered)-' brass with 63 wt.% Zn following pulsed laser-induced melting. The 6' layer is interpreted to mean that the metastable P phase (bcc) formed on the liquid-solid interface as they substrate attempted to regrow, and that fi ordered to 6' (B2) during cooling. The fi formation implies that undercoolings > 16 K were attained during the attempted regrowth of they phase.
