Abstract
The present study is focused on the evolution of microstructure of silicon steel (Fe-Si 6 wt%) after treatment by pulsating water jet (PWJ). The various stages of erosion by pulsating water jet have been studied. The initial damage shows formation of depressions and isolates erosion pits. Repeated passing of water initialized further pit formation and coalescence of pits to craters. During this stages small cracks formation was observed. The repeated passing of water induced deepening of the craters and material removal. The PWJ caused plastic deformation and increase of values of hardness of the subsurface region. The cleavage fracture was present on contained eroded surface.
