Improvement in the nanoindentation technique for investigation of the time-dependent material properties

Abstract

Abstract An improved nanoindentation technique was developed for dynamic investigation of the time-dependent properties of materials under conditions close to real nanocontact interaction during dry friction, abrasive wear, milling, mechanical alloying and so on. For these purposes the duration of the loading- unloading cycle was reduced to 20ms and a nanocontact fatigue test was performed with the number of reloading cycles reaching 103-105.
