Inappropriate design of the test specimen in hot torsion testing may lead to a high accumulation of heat in the central region of the specimen gauge length and as a result flow localization may occur. To avoid this, knowledge of the variation of temperature rise due to plastic deformation over the specimen gauge length for different specimen geometries is necessary. It is also necessary to estimate the distribution of temperature rise in the event that heat generation is inevitable so that the constitutive equations used are modified accordingly. This paper is devoted to these points.

Hot steel ductility in continuous casting processes is determined by tensile tests of notched cylindrical specimens which are obtained by melting and solidification and then tested after rate-controlled cooling with a new specific device available for any standard test machine. Hot ductility is prop
