From: Influence of nano-VC on the structural and magnetic properties of MnAlC-alloy

(a–c) show the grain boundary distribution for the Mn55Al45C2, Mn55Al45C2(VC)0.5 and Mn55Al45C(VC)1 samples and (d–f) show the corresponding <100> 75˚ and <110> 85˚ twins in red and blue. (g–i) show the local misorientation for the Mn55Al45C2, Mn55Al45C2(VC)0.5 and Mn55Al45C(VC)1 samples. (j,k) illustrate the <100> 75° and <110> 85° twin boundaries, respectively. For simplicity, an atomic ratio of Al:Mn = 1:1 was assumed; red atoms (corners) are Al while blue atoms (center) are Mn.
