Surface Topography and Elemental Composition of Craters on the Surface of Stainless Steel

Effect of the pulsed soft X-ray fluxes (PSXF) on the surface topography of magnesium has been investigated. Energy density of the radiation on the specimen surface in a single pulse is ∼13-19 J/cm2. As a result, of melting and subsequent fast solidification, a wavy relief is formed on the surface of magnesium after a single X-ray pulse. Also of crater-like defects were observed on the irradiated surface. Small cracks are formed on the surface of magnesium due to the high cooling rate of the molten metal after exposure to pulsed X-rays
