在 0.001-0.1 MPa 的压力下,在 500 至 1200 K 之间的温度下,利用高度纯化的氢气,对一些不锈钢和高温材料进行了氢渗透率 (φ) 和扩散率 (D) 的精确测量。大多数确定的 φ 和 D 值与温度倒数具有良好的阿累尼乌斯关系。通过比较获得的 φ 和 D 值,讨论了合金元素(特别是 Cr)的影响。
The precise measurements of hydrogen permeability (φ) and diffusivity (D) were performed for some stainless steels and high temperature materials utilizing an extremely purified hydrogen under pressure of 0.001–0.1 MPa at temperatures between 500 and 1200 K. Most of the determined values of φ and D give good Arrhenius relationship against inverse temperature. The effect of alloying elements, particulary, of Cr is discussed by comparing the obtained values of φ and D.
