Transformation Reaction And Corrosion Behaviour Of Two Zirconium Copper Molybdenum Alloys

Investigation to determine the transformation reaction of a Zr-1.0% Cu-1.5% Mo alloy quenched from the beta phase and aged at 500C (930F) and to observe any anomalies in its corrosion behaviour during transformation when tested in steam at 400C (750F) and 1500 psi. The corrosion behaviour of a second alloy, Zr-0.5% Cu-0.5% Mo was also examined. Micro-examinations were made of the corrosion film during transformation and an electron-probe microanalyser was used to investigate the composition of the intermetallic phases.
