o:4094 Application of the simplex methods for testing the influence of cold deformation levels, annealing temperature and chemical content on the mechanical characteristics of some alloys of the Pd-Au system en Abstract: The effect of degree of cold deformation, annealing temperature and chemical composition on the mechanical properties of some Pd-Au alloys was investigated in this work. The HV, Rm and A were determined with different gold content in the alloy and in the function of annealing temperatures at constant annealing time and deformation degree. Optimization of mechanical properties of some Pd-Au alloys were performed by the method of simplex lattice design. Defined mathematical model will allow the selection of operating parameters of the PdAu alloy production process for the catalyst catchers, which can be used to reliably predict the values of mechanical properties such as hardness, tensile strength and elongation that are a key factor in the use of palladium catalysts to catch platinum metals in the high-temperature catalytic processes. Keywords: Pd-Au system, mechanical characteristic, Simplex method, optimization. 91552100 77847305 1552100 978-86-7827-052-9 2024-03-02T18:06:55.264Z 44 no 46 Aleksandra Ivanović Institut za rudarstvo i metalurgiju Bor 3583847 0000-0002-0562-2824 2022 application/pdf 421800 https://unilib.phaidrabg.rs/o:4094 no yes 1 70 669.215 92000004 71A03 Proceedings International October Conference on Mining and Metallurgy (53 ; 2022 ; Bor) 5 8 2022
