Effect of Amount of Deformation on Microstructure Evolution During Controlled Cooling of Forgings from Finish-Forging Temperature

Popis výsledku v původním jazyce

The present paper deals with the effect of the amount of deformation introduced during closed-die forging of parts from 30MnVS6 microalloyed steel upon the final microstructure after controlled cooling. As various locations within forged parts experience various accumulated strains, it is not straightforward to estimate the prior recrystallization-controlled microstructural evolution in such locations during cooling from the finish-forging temperature. Material-technological modelling offers an efficient way of dealing with such problems [1]. It uses a small amount of material (a model) and a processing schedule which is identical to the schedule, used with a real-life forging. The simulator applies an exact sequence of deformation and thermal processing steps to the tested sample. As the model is made of the actual material, it can also be used for mechanical testing and microstructure characterization. Therefore, the final properties of forged parts can be documented or predicted with high accuracy without interfering with the manufacturing process [2].
