摘　　要：电解渗氢制备氢含量分别为140±20 ppm(1 ppm=1μg/g)和260±20 ppm的Zr-4管材,通过加载高压气体使管材发生氢化物应力再取向效应,最终获得不同氢化物取向的Zr-4管材。结果表明:以电解参数为105 mA/cm^2×2 h和110 mA/cm^2×(4 h+50 min)进行电解后可分别获得氢含量为140±20 ppm和260±20 ppm的管材。当温度循环为400～200℃,实际升温和降温速率分别约为10℃/min和0.75℃/min时,通过调节压力和保温时间,仅单次热循环即可获得氢化物取向因子高达0.7的管材。Zr-4 tubes with 140±20 ppm(1 ppm=1 μg/g) and 260±20 ppm hydrogen were prepared by using electrolysis hydrogenating method, and these tubes were further undergone the effect of hydride stress reorientation through loading high pressure gas. Finally, Zr-4 tubes with different hydride orientation were received. The results showed that tubes with 140±20 ppm and 260±20 ppm hydrogen can be obtained via electrolysis with 105 mA/cm^2×2 h and 110 mA/cm^2×(4 h+50 min) respectively. When the temperature cycle is 400-200℃ and actual heating and cooling speeds are about 10℃/min and 0.75℃/min respectively, and tubes with the hydride orientation up to 0.7 can be obtained by just one thermal cycle through adjusting the pressure and the holding time.
