Abstract

A series of investigations has been performed to determine the maximum plasticity of Zr1%Nb alloy material. Also, the deformation limits for Zr1%Nb alloy material were determined. Tests in tension and compression were performed. During these tests the basic value of resistance to deformation and plasticity of the Zr-1%Nb alloy was determined under the temperature and strain rate conditions typical of hot deformation processing. The best temperature range is identified for the hot deformation processing of the Zr-1%Nb alloy. Also, a mathematical model is identified for the maximum plasticity as a function of the deformation conditions. That dependence has been used for the development of the high-tech processes for zirconium product manufacturing for nuclear application.

Keywords:
