摘要：

Electron microprobe analysis was utilized to examine the gradient of alloying elements across the weld interface of austenitic/ferritic dissimilar alloy welds. The concentration gradients were converted to martensite start (Ms) temperature gradients and used to explain the differences in martensite layer widths that have been observed in the partially mixed zone (PMZ) of dissimilar welds.
