Having the minor component present in a larger amount than in the eutectic composition of the same components.

过晶的，过低熔的：有大量的小组元，而不是同种组元的共晶组合。

Using a co-electroplating process, it was possible to plate the Au–Sn solder directly onto a wafer at or near the eutectic composition from a single solution.

通过这个电镀共沉积的过程，我们有可能用一种单一的方法将金锡合金固体焊料直接镀在晶片上的低共熔点上或其附近。

Therefore, in thin section castings, for eliminating eutectic carbides and obtaining ferritic matrix, melts treated by re need high carbon content and hypereutectic composition.

在薄壁铸件中获得无游离渗碳体和铁素体基体的稀土球铁的关键是高碳过共晶原铁水。
