eutectic composition

The hi-Cr cast iron with eutectic composition or the composition a little higher than eutectic demonstrated excellent impact abrasive wear resistance, and adding W, Nb and some other elements had no obvious effect on increasing impact abrasive wear resistance.

共晶成分或稍微过共晶成分的高铬铸铁显示良好的抗冲击磨料磨损能力，而添加W、N等提高抗冲击磨损能力不明显。

This eutectic composition has a melting temperature lower than the operating temperature.

这共晶成分的熔化温度低于操作温度.

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。
