Strain-Rate Sensitivity in Hot Forming of Steels - Influence of Microstructure

Original language description

The methodology of determination of strain-rate sensitivity index was developed, based on rolling of a set of samples with the same draught but different speed at defined temperatures. It was shown that initial grain size has nearly negligible influenceon the investigated variable, in contrast to phase composition whose influence is very considerable. Combined influence of strain rate and temperature on deformation resistance of various types of steel was studied. For a selected group of steels a universal equation was set up, which described with a good accuracy impact of reciprocal temperature and chemical composition (expressed simply by nickel equivalent) on strain-rate sensitivity in hot state.
