摘　　要：阐述了在核辐照条件下用“ZFW”系列高密度合金做较大直径(大于220mm)的惯性工件。此系列合金不含钴、密度17.5～18.0g/cm3、抗拉强度≥850MPa、延伸率13 %～21 %、抗辐照剂量1～3×105Gy。“ZFW”高密度合金的性能优于含钴的同类合金。The paper present a series of “ ZFW ” heavy alloys applied in producing larger diameter inertia workpieces(*J220mm) in nuclear irradiation. The series of heavy alloys not contain cobalt, the density of alloys are17.5～18.0 g/cm3; tensile strength is bigger or equal to 850Mpa; percentage elongation is 13～21%; the dosage of anti-nuclear irradiation is 1～3×105 GY and the flaw of ultrasonic inspection not bigger than 1.5mm etc. The properties of “ ZFW ” heavy alloys are much better than cobalt-bearing heavy alloys.
