Abstract

Osnovni cilj ovog rada bio je prikazati mjernu sposobnost instrumentirane indentacijske metode na Step 100 uređaju u svrhu određivanja mehaničkih svojstava.
Teorijski dio rada daje pregled najčešće ispitivanih mehaničkih svojstava, povijesni razvoj insrumentirane indentacijske metode i njezin princip rada te najčešće korišteni indentori.
U eksperimentalnom dijelu prikazane su mjerne mogućnosti Step 100 uređaja, njegova kalibracija te opis provedenih ispitivanja. Također prikazani su prezultati ispitivanja tvrdoće popraćeni statističkim vrijednostima. Prikazana je usporedba rezultata provedenih na dva različita uređaja. Provedena je analiza dobivenih rezultata te su dani zaključci. Također su opisane uočene problematike instrumentirane indentacijske metode.

Abstract (english)

The main aim of this study was to demonstrate the measurement capability of the instrumented indentation method using the Step 100 device for the purpose of determining the mechanical properties of materials.
The theoretical part of the study provides an overview of the most tested mechanical properties, the historical development of the instrumented indentation method, its operating principle and the most used indenters.
The experimental part presents the measurement capabilities of the Step 100 device, its calibration and a description of the conducted tests. The results of hardness test, accompanied by statistical values, are also presented. A comparison of the results obtained on two different devices is shown. An analysis of the obtained results was conducted, and conclusions were drawn. The observed issues with the instrumented indentation method are also described.
