Abstract
Digital image correlation (DIC) is used to analyze local strain distribution in bimetal composite specimens produced by electron beam additive manufacturing from low-carbon steel and austenitic stainless steel in the as-built state and after its annealing at 680 °C and 950 °C. It is found out that plastic deformation tends to localize in each layer of the composites according to the loading stages. The yield stage (n = 0) and the related Lüders deformation are suppressed. In the parabolic hardening stage (n = 0.5), the local elongation strain εxx is observed to form a stationary periodic distribution of localized strain zones. At n ≤ 0.5, there appears a high-amplitude deformation zone, which corresponds to the site of future specimen failure.
