Metallographic studies were made on light microscope and a scanning electron microscope to assess quantitatively and qualitatively the alloy microstructure. It has been shown that the shape, size and distribution of the iron-rich κ−phase precipitates in bronze microstructure significantly affect its mechanical properties. With an increase in the number of small κ−phase precipitates increases the tensile strength of castings, while the presence of large globular precipitates improves ductility. Fragmentation and shape of κ−phase precipitates depends on many factors, particularly on the chemical composition of the alloy, Fe/Ni ratio, cooling rate and casting technology.}, type={Artykuły / Articles}, title={Effect of Microstructure on Mechanical Properties of BA1055 Bronze Castings}, URL={http://www.journals.pan.pl/Content/88028/PDF/15_paper.pdf}, doi={10.2478/afe-2014-0040}, keywords={mechanical properties, Metallography, Ship propeller castings, Aluminium bronze}, }
