hmogeneous boiling, or phase explosion could be an important ab-lation mechanism @5–8#. The phase explosion phenomenon was first investigated in the earlier work of rapid heating of metal wires using a high current electric pulse @9,10#. It occurs when a liquid is rapidly heated and approaches the thermal dynamic criti-cal temperature, and the instability in the liquid causes an explo-sive type of liquid-vapor phase change.
