Formation of texture and twinning at 296 K of “Artificial” polycrystals of an equiatomic Co20Cr20Fe20Ni20Mn20 High-entropy alloy

•“Artificial” polycrystals were created from Co20Cr20Fe20Ni20Mn20 HEA crystals.•The formed texture depends on the rolling direction.•At 296 K, twinning developed in samples with 〈123〉{111} texture at 30 % strain. In the present paper, “artificial” polycrystals of the equiatomic Co20Cr20Fe20Ni20Mn20 high-entropy alloy were obtained for the first time via rolling process of single crystals up to 67 % along the 1¯11 and [001] directions in the rolling plane (011) at 296 K and subsequent annealing at 1423 K for 1 h. It was shown that texture depends on the rolling direction. When rolling along the 1¯11 direction, a 〈012〉{112} texture was formed, and along the [001] direction it was the 〈123〉{111} texture. At 296 K, twinning developed after slip deformation of 30 % in “artificial” polycrystals with the 〈123〉{111} texture and was not observed in samples with the 〈012〉{112} texture.
