通过Fluxing提纯技术和J-quenching快速凝固技术相结合的方法,成功制备了基于工业级原料的Fe80-MoxP13C7(x=0,4,8,12)块体非晶态合金.结果表明,少量的Mo置换Fe能够提高Fe80 P13 C7合金的玻璃化形成能力,当Mo的替换量为8％时,合金的玻璃化形成临界尺寸达到4mm,然而Mo含量的进一步增加则使合金的玻璃化形成能力降低.随着Mo含量的增加,FeMoPC块体非晶态合金的玻璃转变温度(Tg)和起始晶化温度(Tx)单调增加,而冷液相区宽度(△Tx=Tx-Tg)先增大后减小.压缩测试结果显示,随着Mo含量的增加,FeMoPC块体非晶态合金的压缩断裂强度(σf)和塑性应变(εp)都先增大后减小,当Mo含量为8％时,合金的σf和εp都分别达到了最大值3.6 GPa和4.6％.磁性测试结果表明,随着Mo含量从0％增加到12％,FeMoPC块体非晶态合金的饱和磁化强度从1.42T降为0.33T,这可能是由于Mo与Fe原子间反铁磁耦合造成的.
