Abstract
New data on the mechanical properties of Pt92.5Pd4Rh3.5 platinum alloy used in the catalytic systems in chemical industry are presented. The study was conducted in two stages: i) stretching of the wire samples and plotting of the loading diagrams ii) testing of the wire samples stretched on the wire drawing machines. Data on yield strength were plotted to the tensile stress-strain diagram. Combination of the two methods made it possible to obtain data on the strain resistance in the interval of relative reduction of 0 – 93%. The practical value of the obtained results consists in the possibility of using the dependencies in the form of graphs and approximated data to state and solve the specific boundary problems regarding of plastic metal working using, e.g., the finite element method.
