A study was conducted to determine the impact of cold rolling on the evolution of the microstructure of the CuCrFeNiMn high entropy alloy. Cold rolling resulted in the development of crystallographic textures and microstructure evolution. It was observed that the main deformation mechanism during cold rolling of the mentioned alloy is the movement of dislocations and the formation of mechanical twins, which lead to the formation of shear bands by increasing the amount of deformation. Microstructural studies suggest that the decrease in the microhardness of cold-rolled samples is caused by the formation of strain-free grains on the shear bands. The development of strain-free grains is aided by the rotation of subgrains on the shear bands.

CuCrFeNi2Mn0.5高熵合金冷轧微观组织研究

进行了一项研究以确定冷轧对 CuCrFeNiMn 高熵合金微观结构演变的影响。冷轧导致晶体织构和微观结构演变的发展。研究发现，该合金冷轧时的主要变形机制是位错的运动和机械孪晶的形成，通过增加变形量导致剪切带的形成。微观结构研究表明，冷轧样品显微硬度的降低是由于剪切带上无应变晶粒的形成造成的。剪切带上亚晶粒的旋转有助于无应变晶粒的形成。
