Abstract
Annealing of as-cast, high carbon, refractory alloys induces the formation of chromium-depleted zones in the austenite near the carbide-austenite interface. This depletion is a consequence of the drag of solute caused by the coarsening of the carbides. Micro-analytical investigation has been carried out to illustrate the depletion profiles and to obtain a semi-quantitative analysis of the tiny secondary precipitates. The equipment used included an electron microprobe, a scanning transmission microscope equipped with energy dispersive X-ray spectrometer (STEM/EDX)VG501, a transmission electron microscope (JEM200CX), and a scanning electron microscope (JSM-35). Extrapolation of the depletion curve gives the solute content in austenite at the interface. The values were correlated with the available thermodynamic data.
