      abstract     = {The hypo-eutectic medium entropy alloy
                      Al$_{0.75}$CrFeNi$_{2.1}$ was processed by laser powder bed
                      fusion (LPBF). The off-equilibrium solidification conditions
                      prohibited coupled eutectic growth. Instead, the primary
                      face centered cubic phase A1(FCC) solidified with a cellular
                      morphology and the body centered, initially ordered B2(BCC)
                      phase formed as a thin intercellular envelope. During
                      post-build annealing an ultrafine quasi-lamellar pattern
                      evolved following BCC growth and coarsening. The novel solid
                      state transformation from cellular to lamellar morphology
                      was attributed to a pronounced anisotropy of the FCC|BCC
                      phase boundary energy. Microstructure evolution was also
                      studied during continuous heating using in situ high-energy
                      synchrotron X-ray diffraction (HEXRD) carried out at the
                      beamline P07-HEMS of PETRA III (German Electron Synchrotron,
                      DESY). The ultrafine and nano-scale features of the
                      microstructure were quantitatively analyzed by atom probe
                      tomography (APT) in the as-built condition and after
                      isothermal annealing at 950 °C. The benefits of LPBF
                      processing were discussed on the basis of mechanical
                      properties measured by 3-point bending. The estimated
                      tensile properties after annealing at 950 °C/6 h
                      reached YS ≈ 860 MPa, UTS ≈1384 MPa with an
                      elongation at fracture of ≈11\%. Tensile properties in the
                      as-built condition were comparable to martensitic steels.},
