Development of a non-destructive depth-selective quantification method for sub-percent carbon contents in steel using negative muon lifetime analysis
Update: February 9, 2024Professor Kenya Kubo (Major: Chemistry, Environmental Studies) along with other researchers proposed a novel method of quantifying the bulk C content in steel non-destructively using muons. This revolutionary method may be used not only in the quality control of steel in production, but also in analyzing precious steel archaeological artifacts. The research result was published on the Scientific Reports on Saturday, January 20, 2024: https://doi.org/10.1038/s41598-024-52255-5 (DOI)
