Abstract

The article presents the results of a study of the relationship between the microstructure of V95och alloy ingots after homogenization annealing in single- and two-stage modes with the parameters of technological plasticity in the temperature range of 350–450 °C. There has been stablished the dependence from the homogenization mode of the structure and properties of sheets with a thickness of more than 6 mm made of V95och alloy, aged in a new experimental mode and a serial aging mode T2. We selected the modes of homogenization annealing and aging that ensure achievement of the highest level of service characteristics of sheets.
