本文中探討了傳統(tǒng)黃銅與含Bi無鉛黃銅的相分布。Bi在純銅中強烈偏析于晶界處，而在黃銅晶界處沒有觀察到Bi元素分布。研究中發(fā)現(xiàn)黃銅晶界中存在過量的錫，由此阻礙了Bi的析出。

Abstract
Compositional distributions in a classical brass and a lead-free brass containing bismuth have been measured. Bismuth
segregates strongly to the grain boundaries in pure copper but was not observed at the boundaries in the brass. An excess
concentration of tin at the grain boundaries due to coring was observed and prevents the segregation of bismuth.
