Seminar of Prof. Mengying Liu from Washington and Lee University in the US, entitled “In situ investigation of hydrogen-assisted crack initiation in nickel-based alloy 725”. On May 27th, 2024, at noon in the seminar room.
Abstract: When metals are exposed to hydrogen (H)-rich environments, they may lose ductility and fail catastrophically without showing any sign of damage. This problem is known as hydrogen embrittlement (HE). Over the last few decades, extensive research on HE has shown that hydrogen-assisted cracking is a microstructure-sensitive phenomenon.
