【 摘 要 】

Energy dissipation and areas of process instability were investigated in two alloys. The first one was brass, the second one was the steel 9 Cr (P91). The tests were performed on torsion plastometer Setaram and on compression plastometer Gleeble. In the case of the steel 9 Cr identical heat was tested on both plastometers. The resulting 2D or 3D process maps indicate suitable areas of forming temperatures, magnitudes of deformation and strain rates.
