采用工业原料通过水冷铜模铸造法制备了直径为5 mm的Fe69C7.0Si3.5B4.8P9.6Cr2.1Mo2.0Al2.0块体非晶态合金.利用DSC,DTA和XRD对该非晶态合金的热稳定性进行了研究.其玻璃转变温度Tg、过冷液相区△Bx(=Tx-Tg)、约化玻璃转变温度Trg(=Tg/Tl)和玻璃形成能力参数γ(=Tx/(Tg+Tl))分别为784 K,27 K,0.601和0.388.该非晶合金的晶化过程分为两个阶段:首先析出α-Fe相,随后Fe3C,Fe2P,FeB,Fe2B相同时析出.压缩性能测试显示该合金的断裂强度为3870 MPa,Young's模量为177 GPa,弹性形变为2.1%,塑性形变为0.29%.
