Fatigue of Metallic Materials

Improvement of Fatigue Strength of Light Metallic Materials by Cavitation Shotless Peening

Cavitation normally causes severe damage in hydraulic machinery such as pumps, valves and so on. However, cavitation impact can be utilized to surface treatment to improve fatigue strength of metallic materials in the same way as shot peening. A peening method using cavitation impact was named as “cavitation shotless peening” or “cavitation peening” as shots are not required. As increase of sur...

Sustainable Non-Metallic Building Materials

Buildings are the largest energy consumers and greenhouse gases emitters, both in the developed and developing countries. In continental Europe, the energy use in buildings alone is responsible for up to 50% of carbon dioxide emission. Urgent changes are, therefore, required relating to energy saving, emissions control, production and application of materials, use of renewable resources, and to...

Fundamental Aspects of Corrosion of Metallic Materials

Analysis of precipitates in UFG metallic materials

In the present work, new possibilities of the X-ray diffraction for investigations of the 17 phase composition, size, shape and volume fraction of particles in ultrafine-grained (UFG) 18 martensitic steel and the Cu-Cr-Zr alloy have been demonstrated. For the first time, the method of 19 X-ray diffraction in the transmission mode was used to identify particles with a volume fraction of 20 less ...
