Abstract

Določali smo dejanske fizikalne lastnosti različnih jekel. V ta namen smo uporabljali univerzalni hidravlični aparat, programsko opramo LabVIEW in Microsoft Excel. Testirali smo jekla z oznakami Č.0211, Č.3999, Č.1531, Č.4320 in vzmetno jeklo. Za vsako jeklo smo zaradi možnega odstopanja in eksperimentalnih napak izvedli tri ponovitve meritev. Opisali smo teste, ki smo jih izvedli in prikazali potek računanja. Iz meritev smo izračunali vrednosti meje elastičnosti, meje plastičnosti, modula elastičnosti, razteznosti in natezne trdnosti. Iz literaturnih podatkov o vsebnosti kemijskih elementov teh petih vzorcev jekel, smo lahko sklepali o lastnostih jekel. Dobljene rezultate smo primerjali s podatki v strokovni literaturi.

Secondary title:	DETERMINATION OF ELASTICITY MODULUS AND YIELD POINTS OF DIFFERENT STEEL MATERIALS
Secondary abstract:	We determined the actual mechanical properties of different types of steel. To accomplish this we used a universal hydraulic testing machine, computer software called LabVIEW and Microsoft Excel. We tested steels called Č.0211, Č.1531, Č.3999, Č.4320 and spring steel, according to JUS. To avoid the possibility of measurement errors, we conducted the same experiment on each type of steel three times. We described the experiments performed on the steel samples, as well as noted the process of calculating the elastic limit, yield point, elasticity modulus, ducility and ultimate tensile strength. We were able to determine the mechanical properties of the examined steel samples by studying which chemical elements were bonded inside the steel samples. We compared the calculated data to data found in official literature.
