## Description

- description: A brace-type seismic damper made of an Fe-15Mn-11Cr-7.5Ni-4Si alloy
    solidified in the ferrite-austenite (FA) mode and SN490B steel, which can be constructed
    via welding, was proposed. To realize the proposed seismic damper, gas metal arc
    welding was applied to produce similar FMS/FMS fillet welds and dissimilar FMS/SN490B
    fillet weld joints. Based on the Schaeffler diagram, similar and dissimilar welding
    consumables were designed such that the fillet weld metal solidified in the FA
    mode without solidification cracking. Sound similar fillet welded joints were
    obtained using two types of welding consumables with different Cr/Ni equivalent
    ratios although both the similar fillet weld metals had a coarse columnar austenite
    grain structure. These displayed higher tensile strengths (716–736 MPa) and marginally
    lower elongations (67–70%) than the FMS alloy. Moreover, a similar fillet weld
    metal with a chemical composition almost identical to that of the FMS alloy exhibited
    a remarkable low-cycle fatigue life (5740 cycles). This was shorter than that
    of the FMS alloy (9351 cycles) owing to the easier formation of α’-martensite.
    A dissimilar fillet welded joint with a chemical composition within the austenite
    region was produced without solidification cracking. The dissimilar fillet weld
    metal showed high tensile strength (867 MPa) and total elongation (61%). These
    were comparable to those of similar fillet weld metals.
