Influence of methodology for acquiring and processing of experimental data for determination of the value of activation energy at hot forming

Popis výsledku v původním jazyce

Comprehensive set of torsion tests was performed at selected strain rates ranging from 0.02 to 2.3 s-1. Compression tests were realised with use of analogical parameters, however, the range of applied strain rates was moreover extended by the values 12 and 60 s-1. Activation energy was determined for each set of data always by regression analysis of the obtained peak stresses in dependence on the on temperature and strain rate. Its values were determined separately from the data obtained by torsion tests and separately from the data obtained by compression tests, not only at analogical parameters of forming, but also with inclusion of the results obtained with broader range of applied strain rates. The objective of the realised experiments was to verify how deeply the chosen plastometric methods and range of deformation conditions influence calculation of activation energy of the given steel at hot forming, which is very important from the viewpoint of methodology.
