The quenching ability of modified and unmodified cottonseed oils was investigated using AISI 1070 steel. In the event of the quenching, the steel samples immersed in each of five distinct quench media, namely epoxidized cottonseed oil (EC), epoxidized-transesterified cottonseed oil (ETC), transesterified cottonseed oil (TC) and fresh cottonseed oil (FC). Tests and analysis conducted determined mechanical properties and microstructures of the quenched samples. The data obtained showed that ETC outperformed other quench media with hardness value of the quenched sample; 407 HVN (hardness value from the FC-quenched sample) increased to 746 HVN indicating an 83.29% improvement. Notably, in the microstructure of ETC-quenched sample, a unique homogeneous microstructure containing a mixture of lath and plate martensite observed with largest martensite per cent of 95.
使用AISI 1070钢研究了改性和未改性棉籽油的淬火能力。在淬火过程中，将钢样品浸入五种不同的淬火介质中，即环氧化棉籽油（EC）、环氧化酯交换棉籽油（ETC）、酯交换棉籽油（TC）和新鲜棉籽油（FC）。进行的测试和分析确定了淬火样品的机械性能和微观结构。获得的数据表明，ETC在淬火样品的硬度值方面优于其他淬火介质；淬火样品的硬度值从FC淬火样品的407 HVN增加到746 HVN，提高了83.29%。值得注意的是，在ETC淬火样品的微观结构中，观察到一种独特的均匀微观结构，其中包含板条马氏体和片状马氏体的混合物，马氏体百分比最高为95%。
