Seminario de la Prof. Mengying Liu, de la Universidad de Washington and Lee de EEUU, titulado “In situ investigation of hydrogen-assisted crack initiation in nickel-based alloy 725”se llevará a cabo el 27 de mayo de 2024, a las 12:00 del mediodía, en la sala de seminarios.
Resumen: 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.
