Paper Title:
Casting Solidification Behavior of Bimuth in Free-Cutting Copper Alloy
  Abstract

Effect of bismuth on the microstructure and performance of Cu-Se-Bi brass were studied. The microstructure analysis and fracture observation indicated that the content of bismuth has obvious effect on the foundry property of Cu-Se-Bi brass. The bismuth distributes on the boundary of α and β phrase and when the content of bismuth is below 1.0wt%,bismuth freezes on the phrase boundary in form of granule; when the content of bismuth amounts to 2.0wt%,bismuth presents in form of blocks; while when the content of bismuth is beyond 2.5wt%,bismuth lies on the phrase boundary in form of continuous films. The solidification mechanism of bismuth in Cu-Se-Bi brass was discussed through the thermodynamics analysis.
