Abstract

This paper provides a discussion on results of plastometric tests of selected steel grades used to manufacture pipeline components for the power engineering applications as well as for the gas and petroleum industry The formability assessment was conducted under compression conditions using a thermal-mechanical Gleeble simulator. Studies on the dependence of flow stress σp on strain e were conducted at the temperature ranging from 20 to 1100 °C and the strain rate of 1 s-1. The deformation characteristics established for steel were implemented in numerical simulations of the tube bending process with application of local induction heating.

Keywords: Gleeble simulator, plastometric tests, tube bending, numerical simulations
