## Title

- title: Evolution of microstructure and texture in Al-containing CoCrNi medium entropy
    alloys during severe warm-rolling
  title_type: original
  lang: en

## Description

- description: Al as an alloying element could influence the properties of the single-phase
    equiatomic CoCrNi MEA and to understand the effect of Al, different alloys were
    prepared with the different Al concentrations to CoCrNi MEA (AlxCoCrNi). The alloys
    were warm-rolled at 400 °C up to a thickness reduction of 85% and followed by
    isochronal annealing at 700-1100 °C. The microstructure after deformation revealed
    the development of deformation heterogeneities such as shear bands and deformation
    nano-twins.  The evolution of the weak brass component was seen after deformation.
    Different phases, such as BCC and sigma phases evolved upon annealing treatment
    at different temperatures. Higher Al-content MEA (Al9.09) showed comparatively
    finer recrystallized microstructure irrespective of the annealing temperatures.
    The weak recrystallization texture was developed after annealing and the deformation
    texture components, lying on α-fiber, were preserved. These indicated the absence
    of preferential nucleation and growth during annealing. The hardness in the as-cast,
    deformed, and annealed conditions increased with the increase of the Al-content,
    indicating the influence of Al in the strengthening of the AlxCoCrNi MEAs.
