| Popis: | International audience; Formation of annealing twins has been studied from the beginning of 20 th century. The related mechanisms as growth accident, nucleation of twins and nucleation of partial Shockley loops were suggested. The simulation was also realized by molecular dynamics simulations at the atomic scale. In this paper, a microscopic scale simulation of primary recrystallization and twinning by Monte Carlo approach was realized for a nickel alloy. Different twin morphologies were simulated. It showed a possibility of dependence of grain growth direction on twin formation during annealing. The incoherent Σ3 and Σ9 boundaries formation is verified as the indirect outcome after coherent Σ3 formation. |
