Twin boundary reversibility characteristics in α –Fe

Understanding the grain boundary deformation dynamics is very crucial to designing materials with stable microstructures. With this quest, behavior of coherent twin under cyclic shear loading has been studied in α-Fe using molecular simulations understand influence strain amplitude and temperature. Twin exhibited coupled migration along irreversibility character at lower temperatures gained almost perfect reversibility higher around 1500 K. TB more sliding than an increase The stress associated twins was observed fluctuate its average value. This caused by layer propagation through activity 1/6 111 = 1/12 + type edge partial dislocations on {112} plane. Complete complex were noticed presence multiple parallel nanowires. larger size nanowires a proper combination conditions rates; otherwise, it absent. offsetting found be minimal.
