Investigation of Hot Deformation Behavior of 20Kh13 Steel Through Compression Tests

Abstract

The hot deformation behavior of a 20Kh13 (0.2 C–13 Cr) steel was investigated through compression test using Gleeble-3800 thermal-mechanical simulator within the temperature range of 900–1150 °C and the strain rate range of 0.01–10 s−1. The equation of flow stress as a function of Zener–Hollomon parameter Z was obtained. The critical Zvalue was determined below which dynamic recrystallization may occur during hot deformation.
