## Description

- description: The mechanical behavior of multilayer steel structures fabricated via
    wire and arc additive manufacturing (WAAM) has been investigated from the multiscale
    perspective. The multimaterial WAAM approach can control a heterogeneous structure
    and improve its mechanical properties. In this study, WAAM equipment based on
    plasma arc welding was used to fabricate two pairs of single- and duplex-phase
    multilayer steel structures using austenitic and martensitic stainless steel wires.
    The heterogeneity of these structures was characterized through micro-indentation
    tests. In addition, tensile tests of the multilayer structures were conducted
    to evaluate the effect of heterogeneity on macroscopic material properties. Here,
    the deformation behavior of the heterogeneous multilayer steel structures was
    investigated by comparison with the finite element simulations of tensile tests
    in which the finite element models were created according to the estimated local
    elastoplastic properties from the results of micro-indentation tests. The micro-indentation
    tests revealed that the local mechanical properties significantly change during
    WAAM in cases where martensitic stainless steel wire was used. Additionally, strain-induced
    transformation plasticity was particularly observed in duplex cases, caused by
    the metastable austenite phase formed according to the thermal history and through
    the mixing of alloy elements. Thus, the heterogeneity of the multilayer steel
    structures became more complicated than its design and consequently its macroscopic
    mechanical properties exceeded the upper and lower bounds of a micromechanics
    estimation. The results show the potential to fabricate a structure having a unique
    mechanical behavior via the multimaterial WAAM approach.
