Open AccessIn situ synchrotron diffraction and modeling of non-equilibrium solidification of a MnFeCoNiCu alloy
The solidification mechanism and segregation behavior of laser-melted Mn35Fe5Co20Ni20Cu20 was firstly investigated via in situ synchrotron x-ray diffraction at millisecond temporal resolution. The transient compo...
