GRAIN-GROWTH IN METALS WITH STRONG TEXTURES - 3-DIMENSIONAL MONTE-CARLO SIMULATIONS

The commonly used Monte Carlo technique has been applied to simulate n ormal as well as texture-controlled grain growth on 100(3)-square latt ices. For the case of normal grain growth the simulations yield a grai n growth exponent of n approximate to 0.5, provided the modifications of Radhakrishnan and Zacharia [B. Radhakrishnan, T. Zacharia, Simulati on of curvature-driven grain growth by using a modified Monte Carlo al gorithm, Metall. Mater. Trans. A 26A (1995) 167.] are implemented into the algorithm. Microstructures with a strong initial texture exhibit texture changes if the grain boundaries have anisotropic mobilities. ( C) 1997 Published by Elsevier Science B.V.
