求翻译：铁铜合金的铸态组织，随着碳含量的增加呈现出铜组织中最明显的变化是铜的分布由网状逐渐变为断网状，甚至呈岛状分布的变化；基体组织从铁素体、铁素体和少量珠光体到铁素体和大量珠光体；铁铜合金的铸态组织，硬度值随着碳含量增加而逐渐增加的趋势；冲击韧性随着碳含量的变化呈现出先降低后升高趋势。是什么意思？

The cast microstructure of the alloy of iron and copper, with the increase of carbon content, showing the most obvious change in the copper organization is the distribution of copper into a broken mesh from mesh, and even showed the changes in the distribution of island; matrix microstructure from f
