      abstract     = {this study, gas metal arc welding was performed to join an
                      as-rolled CoCrFeMnNi high entropy alloy using Monel400 as
                      the filler wire. The present research findings demonstrate a
                      favorable metallurgical chemical reactionbetween the Monel
                      400 filler and the CoCrFeMnNi high entropy alloy, resulting
                      in compositional mixing withinthe fusion zone that promotes
                      a solid-solution strengthening effect, counteracting the
                      typical low hardnessassociated to the fusion zone of these
                      alloys. The weld thermal cycle induced multiple
                      microstructure changesacross the joint, including variations
                      in the grain size, existing phases and local texture. The
                      grain size was seento increase from the base material toward
                      the fusion zone. An FCC matrix and finely sparse Cr-Mn-based
                      oxidesexisted in both base material and heat affected zone,
                      while in the fusion zone new FCC phases and carbides
                      wereformed upon the mixing of the Monel 400 filler. The role
                      of the filler material on the fusion zone
                      microstructureevolution was rationalized using thermodynamic
                      calculations. Texture shifted from a γ-fiber (in the base
                      material)to a strong cubic texture in the fusion zone.
                      Digital image correlation during tensile testing to
                      fracturecoupled with microhardness mapping revealed that,
                      stemming from the process-induced microstructure changes,the
                      micro and macromechanical response differed significantly
                      from the original base material. This studysuccessfully
                      established a correlation between the impact of the process
                      on the developed microstructural featuresand the resultant
                      mechanical behavior, effectively assessing the
                      processing-microstructure-properties relationshipstowards an
                      improved understanding of the physical metallurgy associated
                      to these advancedengineering alloys. In conclusion, this
                      work provides an important theoretical framework and
                      practical guidancefor optimizing the engineering
                      applications of high entropy alloys.},
