Scanning transmission electron microscopy (STEM) of welds in Fe-Ni-Cr ternary alloys was used to study the nature of partitioning during primary austenite solidification. It was found that concentration profiles obtained by STEM analysis can be used to distinguish between primary ferrite and primary austenite solidified weld structures. Measured alloy concentrations within the cellular structure were also used to estimate the solidification path and tie lines for solidification by primary austenite.
