Sažetak

The presented work presents the results of the research on the influence of the method of hydrogen removal from tin bronze on porosity and tensile strength. The dehydrogenation was carried out by three methods. In the first method, hydrogen was removed utilizing a vacuum furnace, in the second method, the melt was blown with compressed air, and in the third method, the melt was refined with the salt called Ecosal CU 440. Recirculating scrap was used to make samples. For comparative purposes, castings were also made of melted ingots of the alloy. The density of the castings was determined and the effect of the dehydrogenation method on porosity and the tensile strength was determined on this basis.
