摘 要：<正> β-quenching a Zr-1.15 wt％Cr-0.10 wt％Fe alloy produces a martensitic or a Widmanst（a|¨）tten transforma-tion morphology,or a mixture of the two,depending on the cooling rate.For the Widmanst（a|¨）tten structure,orthe mixed martensitic-Widmanst（a|¨）itten structure,a grain boundary phase is observed at most prior-β grainboundaries.X-ray line broadening analysis and the thermoelectric power（TEP）measurements of thesequenched samples show that not only the solubility of alloying elements in α-Zr matrix,but also substructure（microstrain,crystallite size and dislocation density）have an effect on TEP.Thus,TEP measurements are verywell suited for following the structural transformations taking place in Zr alloys during fabrication.
