| Popis: | New generation maraging steel developed by the aeronautical industry meet the highest mechanical standards thanks to the controlled growth of M2C carbides and B2-NiAl precipitates during aging treatment at around 500 °C. However, the literature has reported a low resistance of precipitation-hardened steel to hydrogen embrittlement that is associated with aging treatment and trapping at precipitates or reverted austenite. Thus, in relation to the complex microstructure of X23NiCoCr 13-6-3 maraging steel, hydrogen solubility and trapping was investigated using Thermodesorption Spectroscopy. A high apparent solubility of hydrogen was observed after aging that was attributed to reversible trapping at coherent B2-NiAl precipitates. |
