doi:10.13251/j.issn.0254-6051.2020.05.035

Abstract

Abstract: 99.99% high purity ytterbium was rolled by multipass rolling with total deformation of 35.6% at room temperature, and then was annealed at 240, 270, 300, 330, and 360 ℃, respectively. The effects of annealing process on the microstructure and microhardness of the deformed high purity ytterbium were analyzed. The results show that the optimum annealing process is at 270 ℃ for 0.5 h. After annealing at 270 ℃ for 0.5 h, the deformed high purity ytterbium is fully recrystallized and obtains uniform fine grains with the average grain size of about 22.5 μm, while the hardness decreases to 18.96 HV0.5. With the increase of annealing temperature, the average grain size increases, the microhardness decreases and tends to be stable.

Key words: deformed high purity ytterbium, annealing process, microstructure, microhardness
