Maps of the A longitudinal and B transverse residual elastic lattice strain calculated from the 211 BCC peak shift measured with a 5 mm grid spacing after deposition of each section and cooling to room temperature. Time-resolved C longitudinal and D transverse elastic lattice strains during cooling after each section are calculated based on temperature-corrected reference values using the aligned IR data. Individual data points show the raw data, while lines show data smoothed with a Savitzky-Golay filter47. Colored bands indicate errors calculated based on the discrepancy between temperature calculated between detector 3 and the IR data.
