摘要	With the rapid development of nuclear industry, advanced niobium alloys with high strength and irradiation resistance are urgently required. In this work, a new multi-component Nb80Mo10Zr10Cr10Al5B0.1 alloy has been designed, and the yield strength in compression can reach similar to 1100 MPa, and plastic strain is similar to 11.3%. To reveal the irradiation damage mechanism, both the NbMoZrCrAlB alloy and pure Nb samples have been irradiated by Xe ion at 350 degrees C and 750 degrees C, with the fluence of 2.1 x 10(15) ions/cm(2). The average diameter of Xe bubble under 750 degrees C irradiation is only similar to 2.92 nm in NbMoZrCrAlB alloy, which is smaller than that of pure Nb (similar to 9.22 nm). Consequently, the volume swelling ratio is only 0.04% in NbMoZrCrAlB alloy, which is largely lower than that of similar to 0.65% in pure Nb. Meanwhile, both the average diameter and number density of dislocation loops in NbMoZrCrAlB alloy are obviously decreased compared with pure Nb at the same irradiation temperature. This result should arise from the severe lattice distortion and sluggish diffusion in present NbMoZrCrAlB alloy, which is similar with the high entropy alloy. The present work provides a reference for designing novel Nb based alloys for advanced nuclear materials.
