Bronze, a copper-tin alloy, is widely used to manufacture gears, bearings, and sealing technologies due to its versatile physical, mechanical, and chemical properties . The aim of the present work was to evaluate the effect of biofield treatment on the physical and structural properties of bronze powder. Bronze powder was divided into two samples, one of which served as a control sample and the other sample underwent biofield treatment. Control and treated bronze samples were characterized using X-ray diffraction (XRD), particle size analyzer, scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). The XRD results showed that the unit cell volume in the treated bronze was reduced by up to 0.78% on day 78 compared to the control sample. Furthermore, the crystal size in the treated bronze sample was significantly reduced by up to 49.96% on day 106 compared to the control sample. In addition, biofield treatment significantly reduced the average particle size in treated bronze powder compared to the control sample by up to 18.22%. SEM data showed agglomerated and welded particles in control bronze powder, while fractured morphology at satellite boundaries was observed in treated bronze. The yield strength of bronze powder calculated using the Hall-Petch equation was significantly changed after biofield treatment. FT-IR analysis showed that three new peaks at 464 cm-1, 736 cm-1 and 835 cm-1 were observed in treated bronze compared to control bronze; this indicates that biofield treatment can alter the bonding properties in bronze. Therefore, biofield treatment significantly changed the properties of bronze at physical and structural levels.
