説明
<p>This study aimed to improve the machinability of copper alloys by using sulfur without lead. Tin bronze (Cu–Sn–Zn system) was employed as the base alloy. Specimens were prepared by sand casting methods. Ingots of JIS CAC403 were melted using a high–frequency induction furnace, followed by the addition of an alloy containing sulfur. Specimens were subjected to strength tests and machinability tests. The sulfur was crystallized as sulfide particle composed of Cu2S and ZnS among the branches of dendrite of copper solid solution. There was not high correlation between sulfur content of specimens and tensile strength or breaking elongation. It was considered that more influence on mechanical properties other factors, such as gas dissolution, than sulfur content. When the sulfur concentration was larger than 0.23mass%, machining resistance decreased about 15%. Sulfide particles behaved as a chip breaker. Further Cu2S adhered cutting edge of machining chip, and behaved as solid lubricant.</p>
