为了使Zr-1.1Nb-0.05Cu合金具有良好的耐蚀性，采用了多种制造工艺，并进行了腐蚀和显微组织分析。该合金的制造采用了四种制造工艺，由退火温度和还原程序的组合控制。随着中间退火温度的降低和最终退火温度的降低，材料的耐蚀性提高。由于低温退火降低了析出相的尺寸和分布，因此可以通过中间退火和最终退火条件的协调来控制Zr-1.1Nb-0.05Cu合金的腐蚀速率。
To obtain a good corrosion resistance for a Zr-1.1Nb-0.05Cu alloy, various manufacturing processes were applied, and corrosion and a microstructural analysis were performed. This alloy was manufactured by applying four types of manufacturing processes controlled by a combination of the annealing temperature and reduction schedule. The corrosion resistance was increased with a decreasing intermediate annealing temperature, and a decreasing the final annealing temperature. Since the size and distribution of precipitates was decreased by applying the low temperature annealing, the corrosion rate of the Zr-1.1Nb-0.05Cu alloy could be controlled by a coordination of the intermediate and final annealing conditions.
