在[(CO1-xFex)(0.75)B0.2Si0.05](96)Nb-4体系中制备了直径达4 mm的钴基块体非晶合金。块体非晶合金具有3980~4170 Mpa的超高断裂强度和190~210 Gpa的杨氏模数。块体非晶合金还具有优良的软磁性能，其饱和磁化强度为0.71-0.97T，矫顽力为0.7-1.8A/m，磁导率为1.48-3.25×10(-4)，饱和磁致伸缩为0.55-5.76×10(-6)。首次成功合成了具有超高断裂强度和极低磁致伸缩的软磁性能的Co-Fe-B-Si基块体非晶合金，为Co基块体非晶合金作为新型工程材料和功能材料的发展奠定了基础。(C)2006年美国物理研究所。
Co-based bulk glassy alloys with diameters up to 4 mm were formed in a [(Co1-xFex)(0.75)B0.2Si0.05](96)Nb-4 system. The bulk glassy alloys exhibit a superhigh fracture strength of 3980-4170 MPa and Young's modulus of 190-210 GPa. The bulk glassy alloys also exhibit excellent soft-magnetic properties, i.e., high saturation magnetization of 0.71-0.97 T, low coercive force of 0.7-1.8 A/m, high permeability of 1.48-3.25x10(4), and extremely low saturation magnetostriction of 0.55-5.76x10(-6). The first successful synthesis of the Co-Fe-B-Si-based bulk glassy alloys exhibiting superhigh fracture strength and excellent soft-magnetic properties with extremely low magnetostriction is encouraging for future development of Co-based bulk glassy alloys as new engineering and functional materials.
