Abstract

Hot isostatic pressing (HIP) is a promising way to improve the quality of structural materials, and therefore the structures themselves. The article presents the results of experimental studies on the application of technology for processing critical products made of AISI 6150 steel in order to reduce the number of pores in material and formed weld. The influence of HIP process on the structure of AISI 6150 steel samples was investigated using x-ray computed tomography. The experimental results show a significant improvement in structure of material, a decrease in the number and size of pores relative to the initial values. The experiments presented in this work were carried out on the basis of a HIP setup located at Vladimir State University.
