## residual stress distribution as a function of depth in

### Non

2019/2/15The residual stress distribution as a function of depth in a sapphire/Ti6Al4V brazing joint is non-destructively measured using Raman Spectra for the first time. A modified method that is suitable for brazing joints is developed to deconvolute the actual residual stress value in each depth from the measured averaged stress value.
