abstract = {In the present work, a quaternary CoCrFeNi high entropy
alloy (HEA) is investigated by means of high energy
synchrotron X-ray diffraction (SYXRD) and small angle
neutron scattering (SANS). At the as-forged state, the
microstructure of CoCrFeNi HEA is pure austenite. The
as-cast dendritic structure has been eliminated by the hot
forging at about 1100 °C and the average grain size
obtained is approximately 11.6 μm. The result shows
pronounced lattice distortion phenomenon in CoCrFeNi HEA,
which supposedly contributes to the solid solution
strengthening of the alloy. The CoCrFeNi HEA exhibits good
yield strength (Rp0.2 = 710 MPa at room temperature
and Rp0.2 = 660 MPa at 500 °C). The small angle
neutron scattering results further indicate the local
ordering effect in the fcc solid solution of CoCrFeNi HEA at
both room temperature and at 500 °C after tensile
deformation.},
