Abstract
This paper gives a detailed analysis of the rapidly solidified layers formed by low energy high current pulsed electron beam (LEHCPEB) on a D2 steel. The results of electron backscattering diffraction (EBSD) measurements revealed that the microstructures and phase components of the steel vary dramatically through the melted layer and the heat affected zone. The exact nature of the graded structure also changes with the number of pulses. The phase transformation paths, which vary with depth and in different areas (close to or far away from the carbides) of the melted layer, are determined by local composition gradients induced by the LEHCPEB treatment.
