“…For example, it was proposed from the observation of damaged materials that a material is damaged by both a strong cavitation impact and a weak cavitation impact, where a strong one generates a pit or a crack on the surface of the material and a weak one causes fatigue owing to repeated impacts on the surface. 2) It is also observed from a microstructural point of view that cavitation impact improves hardness, 3) induces phase transformation, 4) provides residual stress in metals, [5][6][7][8] generates dislocations in a single crystal of magnesium oxide, 9) and causes highspeed deformation of metals 10) and that crystal orientations, 11,12) microstructures, and alloying elements 13) influence the erosion behavior of a material. However, although various investigations on cavitation erosion have been carried out as mentioned above, there remain unsolved problems on the mechanism of erosion of materials, and the cause of erosion cannot be said to be completely understood.…”

To clarify the erosion mechanism of cavitation, we pay attention to the internal changes in grains caused by cavitation impact. The vibratory cavitation test based on ASTM G32 was carried out and the cross section of directly under the eroded surface of a specimen was observed using the electron backscattering diffraction (EBSD) technique. The situations of grain boundaries and the changes in the crystal orientations of grains in aluminum, copper, and steel were analyzed. As a result, the following observations were made. Cavitation impact causes grain refining of sub-micrometer order near the eroded surface. There exist small changes in crystal orientation in grains. In steel, grain boundaries were generated on the eroded surface and were growing inward in the grain. Finally, the mechanism of internal deformation of grains caused by cavitation impact was discussed.

a b s t r a c tDermal flap reconstruction in the oral cavity in a patient complicated with psoriasis vulgaris has not been described yet. Here, we report the case of a 33-year-old man with untreated psoriasis vulgaris who was diagnosed with right tongue SCC (T4aN0M0). Surgery is our preferred approach in such cases, and flap reconstruction was deemed necessary after resection. Because of psoriasis vulgaris, the donor site exhibited erythema, rash, and scaling. Surgery comprising forearm dermal flap reconstruction following palliation of cutis symptoms was performed. Currently, 2 years after surgery, there have been no symptoms of psoriasis vulgaris in the oral cavity and no tumor recurrence.
