球墨鑄鐵是屬于脆性材料，首先，鑄鐵意味著含碳量大于百分之二點(diǎn)一（球墨鑄鐵含碳量在百分之三點(diǎn)五到百分之三點(diǎn)九，金相**是：鐵素體+珠光體），含碳量高，其硬度肯定高，其次，對(duì)球墨進(jìn)行球化處理，意味著金屬微粒尺寸變小，這同樣也會(huì)提高材料強(qiáng)度，硬度。所以一般而言球墨鑄鐵的硬度很大（肯定高于一般的鋼）。但是有時(shí)對(duì)一些球墨鑄鐵做沖擊韌性實(shí)驗(yàn)，研究其斷口，斷口形貌表現(xiàn)韌窩斷口，說(shuō)明其為韌性斷裂。鑒于研究上的習(xí)慣，球墨鑄鐵我們習(xí)慣稱(chēng)之為脆性材料。
