Abstract

The microstructure and properties of cast chromium bronzes with varying Zr contents obtained by different treatment methods were characterized by using optical microscopy, scanning electron microscopy, energy dispersive X-ray spectrometry, and X-ray diffraction. In the specimens with the same composition, the precipitated chromium phase particles in specimens treated by quenching and aging were more granular than those in specimens treated by aging. The precipitated Cr phase was clearly refined and segregated when zirconium was added to the melt. With the addition of zirconium, the tensile strength of the alloy increased by about 3 %, but its electrical conductivity decreased by about 9 %.
