Abstract
The measurement of stress corrosion cracking (SCC) susceptibility of metallic materials with a wide composition range is a daunting task. In this work, based on the consistent relationship between corrosion product film induced stress and SCC susceptibility, we present a high-throughput strategy to quickly evaluate the SCC susceptibility of metallic materials via in-situ stress measurements utilizing highly sensitive microcantilever arrays, combinatorial deposition and scanning laser beam. Using this approach, we fabricated composition gradient Cu–Zn alloy thin films onto the microcantilever arrays, and quickly established a relationship between the alloy compositions and SCC susceptibility within a broad composition range.
