The morphologies of intermetallic phases (IMCs) during directional solidification the Sn-Cu (L+Cu3Sn→Cu6Sn5) and Sn-Co (L+CoSn→CoSn2) peritectic systems were analyzed. primary Cu3Sn Cu6Sn5 in alloy are IMCs whose solubility ranges narrow, while both CoSn CoSn2 nil equilibrium condition. experimental results before acid corrosion shows that dendritic morphology can be observed. investigation on ...
