Effects of Solute Segregation on the Mobility and Mechanical Properties of {101¯2} Coherent Twin Boundary in Magnesium

•16 solute elements are selected to study the effects of solute segregation on the mobility and mechanical properties of {101¯2} CTB.•Pinning limit and pinning efficiency are associated to different factors of solute segregation.•The toughness and strength of {101¯2} CTB can be readily modified by the solute segregation.•The effects on the CTB mobility and mechanical properties are closed related to the segregation propensity.
