Abstract. The paper presents the results of the theoretical study of the effect of strain rate hardening (viscosity) of the capsule material on the process of hot isostatic pressing of a long cylindrical can with powder (so that the influence of lids can be neglected). Relations are obtained that make it possible to evaluate the qualitative estimations of the processes taking place at different stages of the HIP process. Calculations are made for the capsule shrinkage values.
