Abstract

Material, obtained by HIP-consolidated powder of Ni-base superalloy VZH172 had been investigated. Influence of HIP temperature on grain microstructure of consolidated material was determined; distribution of eutectic phase in structure was investigated. Mechanical testing of the HIP-processed blank of VZH172 alloy after heat-treatment was carried out. The results were compared with the properties of wrought material produced by the conventional technology.
