The nanoindentation behaviours of single crystalline silicon samples has gained wide attention in recent years, because of the anomaly effects in the loading curve, caused by the pressure induced phase transformation of silicon. To further enlighten

Pop-in effect in Ge- and Si-coated single-crystalline Si

Autor: Péter M. Nagy, Erika Kálmán, Attila Csik, Kálmán Vad

Publikováno v: International Journal of Materials Research. 99:858-861

In nanoindentation tests the pop-in effect is a sudden increase in penetration depth without an increase in load, caused by some special effect because of the smaller specific volume of the high-pressure phase in Si. It has been investigated in Si sa

Nanomechanical characterization of relaxation processes in As–S chalcogenide glasses

Autor: Erika Kálmán, Michael Trunov, Péter M. Nagy, Sergey Dub

Publikováno v: International Journal of Materials Research. 98:365-369

Nanoscale mechanical properties of As – S binary chalcogenide glasses for bulk and thin-film samples have been studied, using the nanoindentation technique for a step loading procedure. All components of glass deformation (plastic, elastic. and vis

AFM Investigation of Steels Surfaces Worn in HFRR Tests

Autor: Erika Kálmán, Péter M. Nagy, Zs. Oláh, D. Aranyi

Publikováno v: Materials Science Forum. :285-290

Radical reduction of sulphur content in diesel fuel from the mid 90’s had disastrous impact on diesel fuel’s lubricity. Due to the desulphurization process the lubricity of diesel fuel dropped significantly and got crucial nowadays. The lubricity
