Abstract

The microstructural features associated with the active eutectoid decomposition of a near eutectoid alloy Zr-3 wt.% Fe on β quenching were studied. The effects of aging after β quenching, and of furnace cooling from the β phase field were also studied. Aging below the eutectoid transformation temperature resulted in the replacement of the lamellar structure by a distribution of globular Zr₃Fe precipitates in the α matrix, with a concomitant reduction in strength. Furnace cooling from the β phase field resulted in the formation of Zr₂Fe precipitates, suggesting that the formation of Zr₂Fe and Zr₃Fe phases were competitive process.
