Abstract

Namen diplomskega dela je bil izvesti natezne preizkuse različnih zlitin ter pridobljene rezultate primerjati. Natezne preizkuse smo izvajali na univerzalni napravi za preizkušanje mehanskih lastnosti HMT.20 EH. Preizkušali smo aluminijaste in bakrene zlitine. Pred pričetkom testiranja smo trem preizkušancem iz istega materiala izmerili začetno dolžino in premer, po končanem nateznem preizkusu še končni premer in dolžino. Podatek o maksimalni sili, s katero smo obremenjevali posamezen preizkušanec, se je izpisal v računalniškem programu Stiro Lab, kjer se je v realnem času izrisovala tudi krivulja odvisnost raztezka od sile. Podatke, ki so se izrisovali v računalniškem programu, smo prenesli v program Excel, kreirali krivuljo in na osnovi začetnega naklona premice določili modul elastičnosti materiala. Izračunali smo še raztezek, natezno trdnost, mejo elastičnosti in mejo plastičnosti. Dobljene vrednosti smo primerjali z literaturnimi in na podlagi teh sklepali na mehanske lastnosti preizkušane zlitine oziroma kovine.

Secondary title:	COMPARING RESULTS OF TENSILE TEST FOR ALLOYED MATERIAL SPECIMENS
Secondary abstract:	The purpose of the thesis was to perform tensile tests of different alloys and to compare the obtained results. Tensile tests were carried out on a universal device for testing the mechanical properties HMT.20 EH. We tested the aluminum and copper alloys. Before we started the test, we measured the initial length and diameter of the three test pieces of the same material, and after the tensile test we measured the final diameter and length. The data about the maximum force, with which we tested each specimen, was displayed on the computer program STIRO Lab, where the elongation force dependence curve was plotted in real time. We transferred the plotted data from the software over to MS Excel, where we created the curve, and based on the initial slope of the line, we determined the elasticity modulus of the materials. We also calculated the elongation, tensile strength, elasticity limit and plasticity limit. We compared our results with the results from other literature, and based on it, we concluded on the mechanical properties of the tested alloy or metal.
