Abstract
The angle misorientation distribution of martensite formed from electric current treated and non-treated austenite samples are studied using electron backscatter diffraction. The electric currents are pulsed with a loading width of 80 μs, at a frequency of 100 Hz and current density of 4.21 A/mm2 supplied by a DC Voltage. The majority of angle misorientations are < 5° and exist within the martensite grains, while only a minority of all misorientations are derived from the prior austenite grain boundary and were found to lie in the range 20–50°. Distinct textures develop in both electric current treated and non-treated samples with increased quenching temperature. Analysis of the prior austenite shows reduced grains in the electric current treated samples at all quenching temperatures considered.
