WebThe two most common types of intermetallics that are seen are tin/copper (SnCu) and tin/nickel (SnNi) intermetallics. Tin copper intermetallics will occur in 2 distinct phases. The first phase of CuSn intermetallic is formed nearest the copper interface and is designated as ‘e-phase’ Cu 3Sn intermetallic. A layer of ‘n-phase’ Cu 6Sn 5 will The solidifying behavior depends on the alloy composition. Pure metals solidify at a certain temperature, forming crystals of one phase. Eutectic alloys also solidify at a single temperature, all components precipitating simultaneously in so-called coupled growth. Non-eutectic compositions on cooling start to first precipitate the non-eutectic phase; dendrites when it is a metal, large crystals when it is an intermetallic compound.
