Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

This study investigates the embrittlement of TiAl after high‐temperature air exposure. The loss of room‐temperature tensile ductility persists even when tested under liquid nitrogen (−196 °C), with brittle fracture occurring at higher stress levels than typical room‐temperature f...
