| Popis: | The objective of the paper is a mutual comparison of different methods for evaluation of mechanical properties of surface layers. Mechanical properties were tested with the use of nanoindentation and microindentation tests. Different loads and constant deformation speed were used in both cases. For the evaluation of mechanical properties, the AISI 304 type Chromium-Nickel steel commonly used in mechanical engineering industry was tested. Knowledge of relations and differences between nano and micromechanical properties is necessary for understanding of mechanical processes continuously occurring in surface layers during cutting processes. Cilj rada je međusobna usporedba različitih metoda za ocjenu mehaničkih svojstava površinskih slojeva. Mehanička svojstva su ispitivana pomoću testova nano i mikro utiskivanja. U oba slučaja su korištena različita opterećenja i konstantna brzina deformacije. Za ocjenjivanje mehaničkih svojstava je korišten krom nikl čelik (AISI 304 tip) koji se vrlo često primjenjuje u strojarstvu. Poznavanje međusobnih odnosa i razlika između nano i mikro mehaničkih svojstava je važno za razumijevanje procesa koji se događaju na površinskim slojevima tijekom procesa rezanja materijala. |
