Plastic deformation in nanocrystalline TiN at ultra-low stress: An in situ nanoindentation study

Plastic deformation in nanocrystalline TiN at ultra-low stress: An in situ nanoindentation study

It is well adopted that a majority of ceramic materials have low ductility and the plastic yielding in crystalline ceramics occurs succeeding elastic deformation. Here by using in situ nanoindentation we show, however, that in nanocrystalline TiN, massive non-elastic events, such as grain rotation a...

Zusammenfassung:It is well adopted that a majority of ceramic materials have low ductility and the plastic yielding in crystalline ceramics occurs succeeding elastic deformation. Here by using in situ nanoindentation we show, however, that in nanocrystalline TiN, massive non-elastic events, such as grain rotation and grain boundary (GB) sliding, occur at ultra-low stresses (
