Abstract
<p> Lead-free bronze castings dispersed with sulfide particles, whose main composition is the same as JIS CAC411, and which contains over 0.05mass% phosphorus as a residual element, were prepared. Tensile test, fluidity test, microstructure test, and pressure toughness test of the lead-free bronze castings were carried out. Results of tensile tests on JIS CAC406 castings, which are used as common bronze castings, show that the elongation of some specimens containing over 0.05mass% phosphorus is below the JIS requirement of 15%. In contrast, the elongation of the lead-free bronze castings with dispersed sulfide particles was over 15% even when phosphorus content was increased to about 0.1mass%. Increasing the phosphorus content improves the fluidity of the lead-free bronze castings and realizes excellent pressure toughness. In addition, the results of measurement of elemental distribution by EPMA reveal the presence of regions composed of phosphorus and nickel near the sulfide particles. This suggests that a certain amount of phosphorus exists as a compound composed of phosphorus and nickel.</p>
