Effect of Deformed Workpiece Temperature Inhomogeneity on Mechanical Properties of Thin-Walled Steel Vessels During Treatment in a Rolling and Pressing Line

摘要

Test helical rolling is conducted with additional hot stamping of thin-walled vessels made from steel 50. Temperature is determined through an object cross section during hot forming. Changes in metal mechanical properties and microstructure are established for thin steel vessels during a transient temperature-deformation regime in a rolling and pressing line.
