Notes:
For the investigation of retained strains during hot forming, which are related to thedislocation structure, single and double hit compression tests were carried out at differenttemperatures and strain rates for a stainless steel. Using microhardness measurements the retainedstrains after the first and second pass were investigated as a function of the amount of deformation,temperatures as well as strain rates and dwell durations. In general, the retained strain decreaseswith increasing dwell durations in both the deformed and recrystallized grains, respectively. At agiven total amount of deformation in a double hit compression, the retained strains for the asdeformed unrecrystallized grains are reduced for a lower deformation in the first hit. For therecrystallized grains the retained strain increases, when comparing double hit with single hitcompression
