High-resolution digital image correlation is coupled to electron back-scattered diffraction to probe the strain localization behavior of the HfNbTaTiZr refractory high entropy alloy, at room temperature, during monotonic tensile deformation. Slip activity is studied quantitatively, on a large representative region encompassing a variety of crystallographic orientations, in a statistical manner. Two populations of grains are identified regarding how strain localizes in their interior: a vast majority of the grains exhibit a high density of apparently straight slip bands of low intensity, while the remaining grains show few but very intense and wavy slip bands. This behavior is discussed in regards to dislocation glide and cross-slip processes.
