class="khcont">作為鋼的替代品，1949年人類開發(fā)了球墨鑄鐵。鑄鋼含碳量少于0.3%，而鑄鐵和球墨鑄鐵含炭量量則至少為3%。鑄鋼中的低含碳量使得作為游離石墨存在的碳不會形成結(jié)構(gòu)薄片。鑄鐵內(nèi)的碳天然形式是游離石墨薄片形式。在球墨鑄鐵內(nèi)，這種石墨薄片通過特殊的處理方法變化成微小的球體。這種改進(jìn)后的球體使得使得球墨鑄鐵比鑄鐵和鋼相比具有更加優(yōu)異的物理性能。正是這種碳的球狀微觀結(jié)構(gòu)，使得球墨鑄鐵具有更加良好的展延性和抗沖擊性，而鑄鐵內(nèi)部的薄片形式導(dǎo)致鑄鐵沒有展延性。通過鐵素體基體可獲得的展延性，因此，所有美國尼伯科球墨鑄鐵的壓力負(fù)載部件都經(jīng)過鐵素體化退火周期的工藝處理。球墨鑄鐵內(nèi)部的球狀結(jié)構(gòu)也能夠鑄鐵內(nèi)部的薄片石墨容易產(chǎn)生的裂縫現(xiàn)象。在球墨鑄鐵的微觀照片中，可以看見裂縫游行到石墨球后終止。在球墨鑄鐵行業(yè)內(nèi)，這些石墨球稱為“裂縫終結(jié)者”，因為它們具有阻止斷裂的能力。<br /> 有時，球墨鑄鐵被稱為“兩個世界里的”金屬，意思是球墨鑄鐵具有鑄鋼的強(qiáng)度，也有鑄鐵優(yōu)異的抗腐蝕性。<br /> 球墨鑄鐵與鑄鐵（灰鑄鐵）的比較與鑄鐵相比，球墨鑄鐵在強(qiáng)度方面具有的優(yōu)勢。球墨鑄鐵的抗拉強(qiáng)度是60k，而鑄鐵的抗拉強(qiáng)度只有31k。球墨鑄鐵的屈服強(qiáng)度是40k，而鑄鐵并沒有顯示出屈服強(qiáng)度，并且終出現(xiàn)斷裂。球墨鑄鐵的強(qiáng)度-成本比遠(yuǎn)遠(yuǎn)優(yōu)于鑄鐵。(請參閱83頁有關(guān)機(jī)械性能的比較)。球墨鑄鐵在耐腐蝕性方面與鑄鐵相同。</div><p><img
