title = "Deformability and quantitative description of the microstructure of hot-deformed A-286 superalloy",
abstract = "The influence of initial soaking and parameters of hot plastic working on the deformability and microstructure of the A-286 superalloy have been presented. The research was performed on a torsion plastometer in the range of temperatures of 900 - 1150 °C, at a strain rates of 0.1 s-1 and 1.0 s-1. Plastic properties of the alloy were characterized by the worked out flow curves and the temperature relationships of flow stress and strain limit. The structural inspections were performed on microsections taken from plastometric samples after so-called {\textquotedblleft}freezing{\textquotedblright}. The stereological parameters as the recrystallized grain size, inhomogenity and grain shape have been determined. Functional relation between the average grain area and the Zener-Hollomon parameter has been developed and the activation energy for hot working has been estimated.",
