Mechanically-Driven Electronic and Structural Disorder in TiO2 Passive Films: Interfacial Gateway to Stress Corrosion Cracking of NiTi SMAs in Sustainable Concrete Infrastructure
NiTi shape memory alloys (SMAs) are increasingly considered for seismic energy-dissipating devices embedded in reinforced concrete, where passive film stability under simultaneous mechanical and chemical attack remains poorly understood. This study examines the electrochemical and mechanical degradation of NiTi under s...
