| 摘 要： | 本文研究了18Ni马氏体时效钢氢陷阱捕集行为的热放氢法。结果表明,451K峰高的变化与析出相颗粒的数量及分布有关。未时效样品捕集氢最少,时效3h最多。并测得氢陷阱放氢激活能为23.2kJ/mol。

| Abstract: | The inieraction of hydrogen with intetface between the precipitates and the martens-itic matrix in 18Ni maraging steel has been studied by means of thermal hydrogen evolutiontechnigue using gas chromatograph as hydrogen detector. An evolution rate peak has been obser-ved at 451K. The hight of the peak relates to the amount and distribution of the precipitates.The activation energy needed to escape the hydrogen from the trap sites is 23.2 kJ/mol. |
