摘要: 利用高压釜渗氢Zr-4管材对图谱法确定试样的高氢含量(大于200 ppm)进行了研究。结果表明：氢化物为δ相。纵截面不适合统计氢化物面积分数。金相观测倍数可能会影响横截面内测定的氢化物面积分数。用横截面内氢化物面积分数作为体积分数计算确定的氢含量比实际值高。本实验最终建立了氢化物面积分数与体积分数的换算方法并获得了换算公式。
Abstract: Zr-4 tubes hydrogenated with autoclaves were used to investigate the diagram method to deter-mine the high hydrogen contents of samples (>200 ppm). The results show that the hydride is δ-phase. The longitudinal sections are not suitable for statistical calculating the area fractions. Op-tical magnifications can affect the measurement of the area fractions of hydrides in the cross sections. When the area fractions of hydrides in the cross sections are regarded as the volume fractions, the calculated hydrogen contents are higher than actual values. Finally, in this research, a conversion method is established between the area fraction and the volume fraction of hydrides and further a conversion equation is obtained.
